+7z ANSI-C Decoder 9.35
+----------------------
+
+7z ANSI-C provides 7z/LZMA decoding.
+7z ANSI-C version is simplified version ported from C++ code.
+
+LZMA is default and general compression method of 7z format
+in 7-Zip compression program (www.7-zip.org). LZMA provides high 
+compression ratio and very fast decompression.
+
+
+LICENSE
+-------
+
+7z ANSI-C Decoder is part of the LZMA SDK.
+LZMA SDK is written and placed in the public domain by Igor Pavlov.
+
+Files
+---------------------
+
+7zDecode.*   - Low level 7z decoding
+7zExtract.*  - High level 7z decoding
+7zHeader.*   - .7z format constants
+7zIn.*       - .7z archive opening
+7zItem.*     - .7z structures
+7zMain.c     - Test application
+
+
+How To Use
+----------
+
+You can create .7z archive with 7z.exe, 7za.exe or 7zr.exe:
+
+  7z.exe a archive.7z *.htm -r -mx -m0fb=255
+
+If you have big number of files in archive, and you need fast extracting, 
+you can use partly-solid archives:
+  
+  7za.exe a archive.7z *.htm -ms=512K -r -mx -m0fb=255 -m0d=512K
+
+In that example 7-Zip will use 512KB solid blocks. So it needs to decompress only 
+512KB for extracting one file from such archive.
+
+
+Limitations of current version of 7z ANSI-C Decoder
+---------------------------------------------------
+
+ - It reads only "FileName", "Size", "LastWriteTime" and "CRC" information for each file in archive.
+ - It supports only LZMA and Copy (no compression) methods with BCJ or BCJ2 filters.
+ - It converts original UTF-16 Unicode file names to UTF-8 Unicode file names.
+ 
+These limitations will be fixed in future versions.
+
+
+Using 7z ANSI-C Decoder Test application:
+-----------------------------------------
+
+Usage: 7zDec <command> <archive_name>
+
+<Command>:
+  e: Extract files from archive
+  l: List contents of archive
+  t: Test integrity of archive
+
+Example: 
+
+  7zDec l archive.7z
+
+lists contents of archive.7z
+
+  7zDec e archive.7z
+
+extracts files from archive.7z to current folder.
+
+
+How to use .7z Decoder
+----------------------
+
+Memory allocation
+~~~~~~~~~~~~~~~~~
+
+7z Decoder uses two memory pools:
+1) Temporary pool
+2) Main pool
+Such scheme can allow you to avoid fragmentation of allocated blocks.
+
+
+Steps for using 7z decoder
+--------------------------
+
+Use code at 7zMain.c as example.
+
+1) Declare variables:
+  inStream                 /* implements ILookInStream interface */
+  CSzArEx db;              /* 7z archive database structure */
+  ISzAlloc allocImp;       /* memory functions for main pool */
+  ISzAlloc allocTempImp;   /* memory functions for temporary pool */
+
+2) call CrcGenerateTable(); function to initialize CRC structures.
+
+3) call SzArEx_Init(&db); function to initialize db structures.
+
+4) call SzArEx_Open(&db, inStream, &allocMain, &allocTemp) to open archive
+
+This function opens archive "inStream" and reads headers to "db".
+All items in "db" will be allocated with "allocMain" functions.
+SzArEx_Open function allocates and frees temporary structures by "allocTemp" functions.
+
+5) List items or Extract items
+
+  Listing code:
+  ~~~~~~~~~~~~~
+
+    Use SzArEx_GetFileNameUtf16 function. Look example code in C\Util\7z\7zMain.c file. 
+    
+
+  Extracting code:
+  ~~~~~~~~~~~~~~~~
+
+  SZ_RESULT SzAr_Extract(
+    CArchiveDatabaseEx *db,
+    ILookInStream *inStream, 
+    UInt32 fileIndex,         /* index of file */
+    UInt32 *blockIndex,       /* index of solid block */
+    Byte **outBuffer,         /* pointer to pointer to output buffer (allocated with allocMain) */
+    size_t *outBufferSize,    /* buffer size for output buffer */
+    size_t *offset,           /* offset of stream for required file in *outBuffer */
+    size_t *outSizeProcessed, /* size of file in *outBuffer */
+    ISzAlloc *allocMain,
+    ISzAlloc *allocTemp);
+
+  If you need to decompress more than one file, you can send these values from previous call:
+    blockIndex, 
+    outBuffer, 
+    outBufferSize,
+  You can consider "outBuffer" as cache of solid block. If your archive is solid, 
+  it will increase decompression speed.
+
+  After decompressing you must free "outBuffer":
+  allocImp.Free(outBuffer);
+
+6) call SzArEx_Free(&db, allocImp.Free) to free allocated items in "db".
+
+
+
+
+Memory requirements for .7z decoding 
+------------------------------------
+
+Memory usage for Archive opening:
+  - Temporary pool:
+     - Memory for uncompressed .7z headers
+     - some other temporary blocks
+  - Main pool:
+     - Memory for database: 
+       Estimated size of one file structures in solid archive:
+         - Size (4 or 8 Bytes)
+         - CRC32 (4 bytes)
+         - LastWriteTime (8 bytes)
+         - Some file information (4 bytes)
+         - File Name (variable length) + pointer + allocation structures
+
+Memory usage for archive Decompressing:
+  - Temporary pool:
+     - Memory for LZMA decompressing structures
+  - Main pool:
+     - Memory for decompressed solid block
+     - Memory for temprorary buffers, if BCJ2 fileter is used. Usually these 
+       temprorary buffers can be about 15% of solid block size. 
+  
+
+7z Decoder doesn't allocate memory for compressed blocks. 
+Instead of this, you must allocate buffer with desired 
+size before calling 7z Decoder. Use 7zMain.c as example.
+
+
+Defines
+-------
+
+_SZ_ALLOC_DEBUG   - define it if you want to debug alloc/free operations to stderr.

+
+7z uses little endian encoding.
+
+7z archive format has optional headers that are marked as
+[]
+Header
+[]
+
+REAL_UINT64 means real UINT64.
+
+UINT64 means real UINT64 encoded with the following scheme:
+
+  Size of encoding sequence depends from first byte:
+  First_Byte  Extra_Bytes        Value
+  (binary)   
+  0xxxxxxx               : ( xxxxxxx           )
+  10xxxxxx    BYTE y[1]  : (  xxxxxx << (8 * 1)) + y
+  110xxxxx    BYTE y[2]  : (   xxxxx << (8 * 2)) + y
+  ...
+  1111110x    BYTE y[6]  : (       x << (8 * 6)) + y
+  11111110    BYTE y[7]  :                         y

+7-Zip method IDs for 7z and xz archives
+---------------------------------------
+
+Version: 18.06
+Date: 2018-06-30
+
+Each compression or crypto method in 7z is associated with unique binary value (ID).
+The length of ID in bytes is arbitrary but it can not exceed 63 bits (8 bytes).
+
+xz and 7z formats use same ID map.
+
+If you want to add some new ID, you have two ways:
+  1) Write request for allocating IDs to 7-Zip developers.
+  2) Generate 8-bytes ID:
+
+    3F ZZ ZZ ZZ ZZ ZZ MM MM 
+
+    3F              - Prefix for random IDs (1 byte)
+    ZZ ZZ ZZ ZZ ZZ  - Developer ID (5 bytes). Use real random bytes. 
+                      
+    MM MM           - Method ID (2 bytes)
+
+    You can notify 7-Zip developers about your Developer ID / Method ID.
+
+    Note: Use new ID, if old codec can not decode data encoded with new version.

+                  GNU LESSER GENERAL PUBLIC LICENSE
+                       Version 2.1, February 1999
+
+ Copyright (C) 1991, 1999 Free Software Foundation, Inc.
+ 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL.  It also counts
+ as the successor of the GNU Library Public License, version 2, hence
+ the version number 2.1.]
+
+                            Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+  This license, the Lesser General Public License, applies to some
+specially designated software packages--typically libraries--of the
+Free Software Foundation and other authors who decide to use it.  You
+can use it too, but we suggest you first think carefully about whether
+this license or the ordinary General Public License is the better
+strategy to use in any particular case, based on the explanations below.
+
+  When we speak of free software, we are referring to freedom of use,
+not price.  Our General Public Licenses are designed to make sure that
+you have the freedom to distribute copies of free software (and charge
+for this service if you wish); that you receive source code or can get
+it if you want it; that you can change the software and use pieces of
+it in new free programs; and that you are informed that you can do
+these things.
+
+  To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights.  These restrictions translate to certain responsibilities for
+you if you distribute copies of the library or if you modify it.
+
+  For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you.  You must make sure that they, too, receive or can get the source
+code.  If you link other code with the library, you must provide
+complete object files to the recipients, so that they can relink them
+with the library after making changes to the library and recompiling
+it.  And you must show them these terms so they know their rights.
+
+  We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+  To protect each distributor, we want to make it very clear that
+there is no warranty for the free library.  Also, if the library is
+modified by someone else and passed on, the recipients should know
+that what they have is not the original version, so that the original
+author's reputation will not be affected by problems that might be
+introduced by others.
+
+  Finally, software patents pose a constant threat to the existence of
+any free program.  We wish to make sure that a company cannot
+effectively restrict the users of a free program by obtaining a
+restrictive license from a patent holder.  Therefore, we insist that
+any patent license obtained for a version of the library must be
+consistent with the full freedom of use specified in this license.
+
+  Most GNU software, including some libraries, is covered by the
+ordinary GNU General Public License.  This license, the GNU Lesser
+General Public License, applies to certain designated libraries, and
+is quite different from the ordinary General Public License.  We use
+this license for certain libraries in order to permit linking those
+libraries into non-free programs.
+
+  When a program is linked with a library, whether statically or using
+a shared library, the combination of the two is legally speaking a
+combined work, a derivative of the original library.  The ordinary
+General Public License therefore permits such linking only if the
+entire combination fits its criteria of freedom.  The Lesser General
+Public License permits more lax criteria for linking other code with
+the library.
+
+  We call this license the "Lesser" General Public License because it
+does Less to protect the user's freedom than the ordinary General
+Public License.  It also provides other free software developers Less
+of an advantage over competing non-free programs.  These disadvantages
+are the reason we use the ordinary General Public License for many
+libraries.  However, the Lesser license provides advantages in certain
+special circumstances.
+
+  For example, on rare occasions, there may be a special need to
+encourage the widest possible use of a certain library, so that it becomes
+a de-facto standard.  To achieve this, non-free programs must be
+allowed to use the library.  A more frequent case is that a free
+library does the same job as widely used non-free libraries.  In this
+case, there is little to gain by limiting the free library to free
+software only, so we use the Lesser General Public License.
+
+  In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of
+free software.  For example, permission to use the GNU C Library in
+non-free programs enables many more people to use the whole GNU
+operating system, as well as its variant, the GNU/Linux operating
+system.
+
+  Although the Lesser General Public License is Less protective of the
+users' freedom, it does ensure that the user of a program that is
+linked with the Library has the freedom and the wherewithal to run
+that program using a modified version of the Library.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.  Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library".  The
+former contains code derived from the library, whereas the latter must
+be combined with the library in order to run.
+
+                  GNU LESSER GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License Agreement applies to any software library or other
+program which contains a notice placed by the copyright holder or
+other authorized party saying it may be distributed under the terms of
+this Lesser General Public License (also called "this License").
+Each licensee is addressed as "you".
+
+  A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+  The "Library", below, refers to any such software library or work
+which has been distributed under these terms.  A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language.  (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+  "Source code" for a work means the preferred form of the work for
+making modifications to it.  For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control compilation
+and installation of the library.
+
+  Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it).  Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+
+  1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+  You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+
+  2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) The modified work must itself be a software library.
+
+    b) You must cause the files modified to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    c) You must cause the whole of the work to be licensed at no
+    charge to all third parties under the terms of this License.
+
+    d) If a facility in the modified Library refers to a function or a
+    table of data to be supplied by an application program that uses
+    the facility, other than as an argument passed when the facility
+    is invoked, then you must make a good faith effort to ensure that,
+    in the event an application does not supply such function or
+    table, the facility still operates, and performs whatever part of
+    its purpose remains meaningful.
+
+    (For example, a function in a library to compute square roots has
+    a purpose that is entirely well-defined independent of the
+    application.  Therefore, Subsection 2d requires that any
+    application-supplied function or table used by this function must
+    be optional: if the application does not supply it, the square
+    root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library.  To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License.  (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.)  Do not make any other change in
+these notices.
+
+  Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+  This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+  4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+  If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library".  Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+  However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library".  The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+  When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library.  The
+threshold for this to be true is not precisely defined by law.
+
+  If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work.  (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+  Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+
+  6. As an exception to the Sections above, you may also combine or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+  You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License.  You must supply a copy of this License.  If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License.  Also, you must do one
+of these things:
+
+    a) Accompany the work with the complete corresponding
+    machine-readable source code for the Library including whatever
+    changes were used in the work (which must be distributed under
+    Sections 1 and 2 above); and, if the work is an executable linked
+    with the Library, with the complete machine-readable "work that
+    uses the Library", as object code and/or source code, so that the
+    user can modify the Library and then relink to produce a modified
+    executable containing the modified Library.  (It is understood
+    that the user who changes the contents of definitions files in the
+    Library will not necessarily be able to recompile the application
+    to use the modified definitions.)
+
+    b) Use a suitable shared library mechanism for linking with the
+    Library.  A suitable mechanism is one that (1) uses at run time a
+    copy of the library already present on the user's computer system,
+    rather than copying library functions into the executable, and (2)
+    will operate properly with a modified version of the library, if
+    the user installs one, as long as the modified version is
+    interface-compatible with the version that the work was made with.
+
+    c) Accompany the work with a written offer, valid for at
+    least three years, to give the same user the materials
+    specified in Subsection 6a, above, for a charge no more
+    than the cost of performing this distribution.
+
+    d) If distribution of the work is made by offering access to copy
+    from a designated place, offer equivalent access to copy the above
+    specified materials from the same place.
+
+    e) Verify that the user has already received a copy of these
+    materials or that you have already sent this user a copy.
+
+  For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it.  However, as a special exception,
+the materials to be distributed need not include anything that is
+normally distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+  It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system.  Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+
+  7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+    a) Accompany the combined library with a copy of the same work
+    based on the Library, uncombined with any other library
+    facilities.  This must be distributed under the terms of the
+    Sections above.
+
+    b) Give prominent notice with the combined library of the fact
+    that part of it is a work based on the Library, and explaining
+    where to find the accompanying uncombined form of the same work.
+
+  8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License.  Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License.  However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+  9. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Library or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+  10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties with
+this License.
+
+  11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply,
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License may add
+an explicit geographical distribution limitation excluding those countries,
+so that distribution is permitted only in or among countries not thus
+excluded.  In such case, this License incorporates the limitation as if
+written in the body of this License.
+
+  13. The Free Software Foundation may publish revised and/or new
+versions of the Lesser General Public License from time to time.
+Such new versions will be similar in spirit to the present version,
+but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Library
+specifies a version number of this License which applies to it and
+"any later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation.  If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+
+  14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission.  For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this.  Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+                            NO WARRANTY
+
+  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.
+
+                     END OF TERMS AND CONDITIONS
+
+           How to Apply These Terms to Your New Libraries
+
+  If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change.  You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+  To apply these terms, attach the following notices to the library.  It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the library's name and a brief idea of what it does.>

+LZMA compression
+----------------
+Version: 9.35
+
+This file describes LZMA encoding and decoding functions written in C language.
+
+LZMA is an improved version of famous LZ77 compression algorithm. 
+It was improved in way of maximum increasing of compression ratio,
+keeping high decompression speed and low memory requirements for 
+decompressing.
+
+Note: you can read also LZMA Specification (lzma-specification.txt from LZMA SDK)
+
+Also you can look source code for LZMA encoding and decoding:
+  C/Util/Lzma/LzmaUtil.c
+
+
+LZMA compressed file format
+---------------------------
+Offset Size Description
+  0     1   Special LZMA properties (lc,lp, pb in encoded form)
+  1     4   Dictionary size (little endian)
+  5     8   Uncompressed size (little endian). -1 means unknown size
+ 13         Compressed data
+
+
+
+ANSI-C LZMA Decoder
+~~~~~~~~~~~~~~~~~~~
+
+Please note that interfaces for ANSI-C code were changed in LZMA SDK 4.58.
+If you want to use old interfaces you can download previous version of LZMA SDK
+from sourceforge.net site.
+
+To use ANSI-C LZMA Decoder you need the following files:
+1) LzmaDec.h + LzmaDec.c + 7zTypes.h + Precomp.h + Compiler.h
+
+Look example code:
+  C/Util/Lzma/LzmaUtil.c
+
+
+Memory requirements for LZMA decoding
+-------------------------------------
+
+Stack usage of LZMA decoding function for local variables is not 
+larger than 200-400 bytes.
+
+LZMA Decoder uses dictionary buffer and internal state structure.
+Internal state structure consumes
+  state_size = (4 + (1.5 << (lc + lp))) KB
+by default (lc=3, lp=0), state_size = 16 KB.
+
+
+How To decompress data
+----------------------
+
+LZMA Decoder (ANSI-C version) now supports 2 interfaces:
+1) Single-call Decompressing
+2) Multi-call State Decompressing (zlib-like interface)
+
+You must use external allocator:
+Example:
+void *SzAlloc(void *p, size_t size) { p = p; return malloc(size); }
+void SzFree(void *p, void *address) { p = p; free(address); }
+ISzAlloc alloc = { SzAlloc, SzFree };
+
+You can use p = p; operator to disable compiler warnings.
+
+
+Single-call Decompressing
+-------------------------
+When to use: RAM->RAM decompressing
+Compile files: LzmaDec.h + LzmaDec.c + 7zTypes.h
+Compile defines: no defines
+Memory Requirements:
+  - Input buffer: compressed size
+  - Output buffer: uncompressed size
+  - LZMA Internal Structures: state_size (16 KB for default settings) 
+
+Interface:
+  int LzmaDecode(Byte *dest, SizeT *destLen, const Byte *src, SizeT *srcLen,
+      const Byte *propData, unsigned propSize, ELzmaFinishMode finishMode, 
+      ELzmaStatus *status, ISzAlloc *alloc);
+  In: 
+    dest     - output data
+    destLen  - output data size
+    src      - input data
+    srcLen   - input data size
+    propData - LZMA properties  (5 bytes)
+    propSize - size of propData buffer (5 bytes)
+    finishMode - It has meaning only if the decoding reaches output limit (*destLen).
+         LZMA_FINISH_ANY - Decode just destLen bytes.
+         LZMA_FINISH_END - Stream must be finished after (*destLen).
+                           You can use LZMA_FINISH_END, when you know that 
+                           current output buffer covers last bytes of stream. 
+    alloc    - Memory allocator.
+
+  Out: 
+    destLen  - processed output size 
+    srcLen   - processed input size 
+
+  Output:
+    SZ_OK
+      status:
+        LZMA_STATUS_FINISHED_WITH_MARK
+        LZMA_STATUS_NOT_FINISHED 
+        LZMA_STATUS_MAYBE_FINISHED_WITHOUT_MARK
+    SZ_ERROR_DATA - Data error
+    SZ_ERROR_MEM  - Memory allocation error
+    SZ_ERROR_UNSUPPORTED - Unsupported properties
+    SZ_ERROR_INPUT_EOF - It needs more bytes in input buffer (src).
+
+  If LZMA decoder sees end_marker before reaching output limit, it returns OK result,
+  and output value of destLen will be less than output buffer size limit.
+
+  You can use multiple checks to test data integrity after full decompression:
+    1) Check Result and "status" variable.
+    2) Check that output(destLen) = uncompressedSize, if you know real uncompressedSize.
+    3) Check that output(srcLen) = compressedSize, if you know real compressedSize. 
+       You must use correct finish mode in that case. */ 
+
+
+Multi-call State Decompressing (zlib-like interface)
+----------------------------------------------------
+
+When to use: file->file decompressing 
+Compile files: LzmaDec.h + LzmaDec.c + 7zTypes.h
+
+Memory Requirements:
+ - Buffer for input stream: any size (for example, 16 KB)
+ - Buffer for output stream: any size (for example, 16 KB)
+ - LZMA Internal Structures: state_size (16 KB for default settings) 
+ - LZMA dictionary (dictionary size is encoded in LZMA properties header)
+
+1) read LZMA properties (5 bytes) and uncompressed size (8 bytes, little-endian) to header:
+   unsigned char header[LZMA_PROPS_SIZE + 8];
+   ReadFile(inFile, header, sizeof(header)
+
+2) Allocate CLzmaDec structures (state + dictionary) using LZMA properties
+
+  CLzmaDec state;
+  LzmaDec_Constr(&state);
+  res = LzmaDec_Allocate(&state, header, LZMA_PROPS_SIZE, &g_Alloc);
+  if (res != SZ_OK)
+    return res;
+
+3) Init LzmaDec structure before any new LZMA stream. And call LzmaDec_DecodeToBuf in loop
+
+  LzmaDec_Init(&state);
+  for (;;)
+  {
+    ... 
+    int res = LzmaDec_DecodeToBuf(CLzmaDec *p, Byte *dest, SizeT *destLen, 
+        const Byte *src, SizeT *srcLen, ELzmaFinishMode finishMode);
+    ...
+  }
+
+
+4) Free all allocated structures
+  LzmaDec_Free(&state, &g_Alloc);
+
+Look example code:
+  C/Util/Lzma/LzmaUtil.c
+
+
+How To compress data
+--------------------
+
+Compile files: 
+  7zTypes.h
+  Threads.h     
+  LzmaEnc.h
+  LzmaEnc.c
+  LzFind.h
+  LzFind.c
+  LzFindMt.h
+  LzFindMt.c
+  LzHash.h
+
+Memory Requirements:
+  - (dictSize * 11.5 + 6 MB) + state_size
+
+Lzma Encoder can use two memory allocators:
+1) alloc - for small arrays.
+2) allocBig - for big arrays.
+
+For example, you can use Large RAM Pages (2 MB) in allocBig allocator for 
+better compression speed. Note that Windows has bad implementation for 
+Large RAM Pages. 
+It's OK to use same allocator for alloc and allocBig.
+
+
+Single-call Compression with callbacks
+--------------------------------------
+
+Look example code:
+  C/Util/Lzma/LzmaUtil.c
+
+When to use: file->file compressing 
+
+1) you must implement callback structures for interfaces:
+ISeqInStream
+ISeqOutStream
+ICompressProgress
+ISzAlloc
+
+static void *SzAlloc(void *p, size_t size) { p = p; return MyAlloc(size); }
+static void SzFree(void *p, void *address) {  p = p; MyFree(address); }
+static ISzAlloc g_Alloc = { SzAlloc, SzFree };
+
+  CFileSeqInStream inStream;
+  CFileSeqOutStream outStream;
+
+  inStream.funcTable.Read = MyRead;
+  inStream.file = inFile;
+  outStream.funcTable.Write = MyWrite;
+  outStream.file = outFile;
+
+
+2) Create CLzmaEncHandle object;
+
+  CLzmaEncHandle enc;
+
+  enc = LzmaEnc_Create(&g_Alloc);
+  if (enc == 0)
+    return SZ_ERROR_MEM;
+
+
+3) initialize CLzmaEncProps properties;
+
+  LzmaEncProps_Init(&props);
+
+  Then you can change some properties in that structure.
+
+4) Send LZMA properties to LZMA Encoder
+
+  res = LzmaEnc_SetProps(enc, &props);
+
+5) Write encoded properties to header
+
+    Byte header[LZMA_PROPS_SIZE + 8];
+    size_t headerSize = LZMA_PROPS_SIZE;
+    UInt64 fileSize;
+    int i;
+
+    res = LzmaEnc_WriteProperties(enc, header, &headerSize);
+    fileSize = MyGetFileLength(inFile);
+    for (i = 0; i < 8; i++)
+      header[headerSize++] = (Byte)(fileSize >> (8 * i));
+    MyWriteFileAndCheck(outFile, header, headerSize)
+
+6) Call encoding function:
+      res = LzmaEnc_Encode(enc, &outStream.funcTable, &inStream.funcTable, 
+        NULL, &g_Alloc, &g_Alloc);
+
+7) Destroy LZMA Encoder Object
+  LzmaEnc_Destroy(enc, &g_Alloc, &g_Alloc);
+
+
+If callback function return some error code, LzmaEnc_Encode also returns that code
+or it can return the code like SZ_ERROR_READ, SZ_ERROR_WRITE or SZ_ERROR_PROGRESS.
+
+
+Single-call RAM->RAM Compression
+--------------------------------
+
+Single-call RAM->RAM Compression is similar to Compression with callbacks,
+but you provide pointers to buffers instead of pointers to stream callbacks:
+
+SRes LzmaEncode(Byte *dest, SizeT *destLen, const Byte *src, SizeT srcLen,
+    const CLzmaEncProps *props, Byte *propsEncoded, SizeT *propsSize, int writeEndMark, 
+    ICompressProgress *progress, ISzAlloc *alloc, ISzAlloc *allocBig);
+
+Return code:
+  SZ_OK               - OK
+  SZ_ERROR_MEM        - Memory allocation error 
+  SZ_ERROR_PARAM      - Incorrect paramater
+  SZ_ERROR_OUTPUT_EOF - output buffer overflow
+  SZ_ERROR_THREAD     - errors in multithreading functions (only for Mt version)
+
+
+
+Defines
+-------
+
+_LZMA_SIZE_OPT - Enable some optimizations in LZMA Decoder to get smaller executable code.
+
+_LZMA_PROB32   - It can increase the speed on some 32-bit CPUs, but memory usage for 
+                 some structures will be doubled in that case.
+
+_LZMA_UINT32_IS_ULONG  - Define it if int is 16-bit on your compiler and long is 32-bit.
+
+_LZMA_NO_SYSTEM_SIZE_T  - Define it if you don't want to use size_t type.
+
+
+_7ZIP_PPMD_SUPPPORT - Define it if you don't want to support PPMD method in AMSI-C .7z decoder.
+
+
+C++ LZMA Encoder/Decoder 
+~~~~~~~~~~~~~~~~~~~~~~~~
+C++ LZMA code use COM-like interfaces. So if you want to use it, 
+you can study basics of COM/OLE.
+C++ LZMA code is just wrapper over ANSI-C code.
+
+
+C++ Notes
+~~~~~~~~~~~~~~~~~~~~~~~~
+If you use some C++ code folders in 7-Zip (for example, C++ code for .7z handling),
+you must check that you correctly work with "new" operator.
+7-Zip can be compiled with MSVC 6.0 that doesn't throw "exception" from "new" operator.
+So 7-Zip uses "CPP\Common\NewHandler.cpp" that redefines "new" operator:
+operator new(size_t size)
+{
+  void *p = ::malloc(size);
+  if (p == 0)
+    throw CNewException();
+  return p;
+}
+If you use MSCV that throws exception for "new" operator, you can compile without 
+"NewHandler.cpp". So standard exception will be used. Actually some code of 
+7-Zip catches any exception in internal code and converts it to HRESULT code.
+So you don't need to catch CNewException, if you call COM interfaces of 7-Zip.

+7-Zip is a file archiver for Windows. 
+
+7-Zip Copyright (C) 1999-2021 Igor Pavlov.
+
+
+License Info
+------------
+
+7-Zip is free software distributed under the GNU LGPL 
+(except for unRar code).
+read License.txt for more infomation about license.
+
+Notes about unRAR license:
+
+Please check main restriction from unRar license:
+
+   2. The unRAR sources may be used in any software to handle RAR
+      archives without limitations free of charge, but cannot be used
+      to re-create the RAR compression algorithm, which is proprietary.
+      Distribution of modified unRAR sources in separate form or as a
+      part of other software is permitted, provided that it is clearly
+      stated in the documentation and source comments that the code may
+      not be used to develop a RAR (WinRAR) compatible archiver.
+
+In brief it means:
+1) You can compile and use compiled files under GNU LGPL rules, since 
+   unRAR license almost has no restrictions for compiled files.
+   You can link these compiled files to LGPL programs.
+2) You can fix bugs in source code and use compiled fixed version.
+3) You can not use unRAR sources to re-create the RAR compression algorithm.
+
+
+LZMA SDK
+--------
+
+This package also contains some files from LZMA SDK
+You can download LZMA SDK from:
+  http://www.7-zip.org/sdk.html
+LZMA SDK is written and placed in the public domain by Igor Pavlov.
+
+
+How to compile in Windows
+-------------------------
+
+To compile the sources to Windows binaries you need Visual Studio compiler and/or Windows SDK.
+You can use latest Windows Studio 2017/2019 to compile binaries for x86, x64 and arm64 platforms.
+Also you can use old compilers for some platforms:
+  x86   : Visual C++ 6.0 with Platform SDK
+  x64   : Windows Server 2003 R2 Platform SDK
+  arm64 : Windows Studio 2017
+  arm   : Windows Studio 2017
+  ia64 (itanium)     : Windows Server 2003 R2 Platform SDK
+  arm for Windows CE : Standard SDK for Windows CE 5.0
+
+If you use MSVC6, specify also Platform SDK directories at top of directories lists:
+Tools / Options / Directories
+  - Include files
+  - Library files
+
+Also you need Microsoft Macro Assembler:
+  - ml.exe for x86 
+  - ml64.exe for x64
+You can use ml.exe from Windows SDK for Windows Vista or some later versions.
+
+There are two ways to compile 7-Zip binaries:
+1) via makefile in command line.
+2) via dsp file in Visual Studio.
+
+The dsp file compiling can be used for development and debug purposes.
+The final 7-Zip binaries are compiled via makefiles, that provide best 
+optimization options.
+
+
+How to compile with makefile

+Some macronames can be defined for compiling with makefile:
+
+PLATFORM
+  with possible values: x64, x86, arm64, arm, ia64
+
+OLD_COMPILER
+  for old VC compiler, like MSCV 6.0.
+
+MY_DYNAMIC_LINK
+  for dynamic linking to the run-time library (msvcrt.dll). 
+  The default makefile option is static linking to the run-time library.
+
+
+
+Compiling 7-Zip for Unix/Linux
+------------------------------
+
+There are several otpions to compile 7-Zip with different compilers: gcc and clang.
+Also 7-Zip code contains two versions for some critical parts of code: in C and in Assembeler.
+So if you compile the version with Assembeler code, you will get faster 7-Zip binary.
+
+7-Zip's assembler code uses the following syntax for different platforms:
+
+1) x86 and x86-64 (AMD64): MASM syntax. 
+   There are 2 programs that supports MASM syntax in Linux.
+'    'Asmc Macro Assembler and JWasm. But JWasm now doesn't support some 
+      cpu instructions used in 7-Zip.
+   So you must install Asmc Macro Assembler in Linux, if you want to compile fastest version
+   of 7-Zip  x86 and x86-64:
+     https://github.com/nidud/asmc
+
+2) arm64: GNU assembler for ARM64 with preprocessor. 
+   That systax of that arm64 assembler code in 7-Zip is supported by GCC and CLANG for ARM64.
+
+There are different binaries that can be compiled from 7-Zip source.
+There are 2 main files in folder for compiling:
+  makefile        - that can be used for compiling Windows version of 7-Zip with nmake command
+  makefile.gcc    - that can be used for compiling Linux/macOS versions of 7-Zip with make command
+
+At first you must change the current folder to folder that contains `makefile.gcc`:
+
+  cd CPP/7zip/Bundles/Alone2
+
+Then you can compile `makefile.gcc` with the command:
+
+  make -j -f makefile.gcc
+
+Also there are additional "*.mak" files in folder "CPP/7zip/" that can be used to compile 
+7-Zip binaries with optimized code and optimzing options.
+
+To compile with GCC without assembler:
+  cd CPP/7zip/Bundles/Alone2
+  make -j -f ../../cmpl_gcc.mak
+
+To compile with CLANG without assembler:
+  make -j -f ../../cmpl_clang.mak
+
+To compile 7-Zip for x86-64 with asmc assembler:
+  make -j -f ../../cmpl_gcc_x64.mak
+
+To compile 7-Zip for arm64 with assembler:
+  make -j -f ../../cmpl_gcc_arm64.mak
+
+To compile 7-Zip for arm64 for macOS:
+  make -j -f ../../cmpl_mac_arm64.mak
+
+Also you can change some compiler options in the mak files:
+  cmpl_gcc.mak
+  var_gcc.mak
+  warn_gcc.mak
+
+makefile.gcc supports some variables that can change compile options
+
+USE_JWASM=1
+  use JWasm assembler instead of Asmc.
+  Note that JWasm doesn't support AES instructions. So AES code from C version AesOpt.c 
+  will be used instead of assembler code from AesOpt.asm.
+
+DISABLE_RAR=1
+  removes whole RAR related code from compilation.
+
+DISABLE_RAR_COMPRESS=1
+  removes "not fully free" code of RAR decompression codecs from compilation.
+
+RAR decompression codecs in 7-Zip code has some additional license restrictions, 
+that can be treated as not fully compatible with free-software licenses.
+DISABLE_RAR_COMPRESS=1 allows to exclude such "not-fully-free" RAR code from compilation.
+if DISABLE_RAR_COMPRESS=1 is specified, 7-zip will not be able to decompress files 
+from rar archives, but 7-zip still will be able to open rar archives to get list of 
+files or to extract files that are stored without compression.
+if DISABLE_RAR=1 is specified, 7-zip will not be able to work with RAR archives.
+
+
+
+7-Zip and p7zip
+===============
+Now there are two different ports of 7-Zip for Linux/macOS:
+
+1) p7zip - another port of 7-Zip for Linux, made by an independent developer.
+   The latest version of p7zip now is 16.02, and that p7zip 16.02 is outdated now.
+   http://sourceforge.net/projects/p7zip/ 
+
+2) 7-Zip for Linux/macOS - this package - it's new code with all changes from latest 7-Zip for Windows.
+
+These two ports are not identical. 
+Note also that some Linux specific things can be implemented better in p7zip than in new 7-Zip for Linux.
+
+
+
+
+Notes:
+------
+7-Zip consists of COM modules (DLL files).
+But 7-Zip doesn't use standard COM interfaces for creating objects.
+Look at
+7zip\UI\Client7z folder for example of using DLL files of 7-Zip. 
+Some DLL files can use other DLL files from 7-Zip.
+If you don't like it, you must use standalone version of DLL.
+To compile standalone version of DLL you must include all used parts
+to project and define some defs. 
+For example, 7zip\Bundles\Format7z is a standalone version  of 7z.dll 
+that works with 7z format. So you can use such DLL in your project 
+without additional DLL files.

+HISTORY of the 7-Zip source code
+--------------------------------
+
+21.07          2021-12-26
+-------------------------
+- The sorting order of files in archives was slightly changed to be more consistent
+  for cases where the name of some directory is the same as the prefix part of the name
+  of another directory or file.
+- TAR archives created by 7-Zip now are more consistent with archives created by GNU TAR program.
+
+
+21.06          2021-11-24
+-------------------------
+- Bug in LZMA encoder in file LzmaEnc.c was fixed:
+  LzmaEnc_MemEncode(), LzmaEncode() and LzmaCompress() could work incorrectly, 
+    if size value for output buffer is smaller than size required for all compressed data.
+  LzmaEnc_Encode() could work incorrectly,
+    if callback ISeqOutStream::Write() doesn't write all compressed data.
+  NCompress::NLzma::CEncoder::Code() could work incorrectly,
+    if callback ISequentialOutStream::Write() returns error code.
+- Bug in versions 21.00-21.05 was fixed:
+  7-Zip didn't set attributes of directories during archive extracting.
+
+
+21.04 beta     2021-11-02
+-------------------------
+- 7-Zip now reduces the number of working CPU threads for compression,
+  if RAM size is not enough for compression with big LZMA2 dictionary.
+- 7-Zip now can create and check "file.sha256" and "file.sha1" text files 
+  that contain the list of file names and SHA-1 / SHA-256 checksums in format 
+  compatible with sha1sum/sha256sum programs.
+
+
+21.03 beta     2021-07-20
+-------------------------
+- The maximum dictionary size for LZMA/LZMA2 compressing was increased to 4 GB (3840 MiB).
+- Minor speed optimizations in LZMA/LZMA2 compressing.
+
+
+21.02 alpha    2021-05-06
+-------------------------
+- 7-Zip now writes additional field for filename in UTF-8 encoding to zip archives.
+  It allows to extract correct file name from zip archives on different systems.
+- The command line version of 7-Zip for macOS was released.
+- The speed for LZMA and LZMA2 decompression in arm64 versions for macOS and Linux 
+  was increased by 20%-60%.
+- Some changes and improvements in ZIP, TAR and NSIS code.
+
+
+21.01 alpha    2021-03-09
+-------------------------
+- The command line version of 7-Zip for Linux was released.
+- The improvements for speed of ARM64 version using hardware CPU instructions 
+  for AES, CRC-32, SHA-1 and SHA-256.

+  7-Zip could not correctly extract some ZIP archives created with xz compression method.
+- Some bugs were fixed.
+
+
+20.02 alpha    2020-08-08
+-------------------------
+- The default number of LZMA2 chunks per solid block in 7z archive was increased to 64.
+  It allows to increase the compression speed for big 7z archives, if there is a big number 
+  of CPU cores and threads.
+- The speed of PPMd compressing/decompressing was increased for 7z/ZIP/RAR archives.
+- The new -ssp switch. If the switch -ssp is specified, 7-Zip doesn't allow the system 
+  to modify "Last Access Time" property of source files for archiving and hashing operations. 
+- Some bugs were fixed.
+
+
+20.00 alpha    2020-02-06
+-------------------------
+- 7-Zip now supports new optional match finders for LZMA/LZMA2 compression: bt5 and hc5, 
+  that can work faster than bt4 and hc4 match finders for the data with big redundancy.
+- The compression ratio was improved for Fast and Fastest compression levels with the 
+  following default settings:
+   - Fastest level (-mx1) : hc5 match finder with 256 KB dictionary.
+   - Fast    level (-mx3) : hc5 match finder with 4 MB dictionary.
+- Minor speed optimizations in multithreaded LZMA/LZMA2 compression for Normal/Maximum/Ultra 
+  compression levels.
+- bzip2 decoding code was updated to support bzip2 archives, created by lbzip2 program.
+
+
+19.02          2019-09-05

+  and the pseudo-random number generator was improved.
+- Some bugs were fixed.
+
+
+18.06          2018-12-30
+-------------------------
+- The speed for LZMA/LZMA2 compressing was increased by 3-10%,
+  and there are minor changes in compression ratio.
+- Some bugs were fixed.
+- The bug in 7-Zip 18.02-18.05 was fixed:
+  There was memory leak in multithreading xz decoder - XzDecMt_Decode(),
+  if xz stream contains only one block.
+- 7-Zip 18.02-18.05 used only one CPU thread for bz2 archive creation.
+- The changes for MSVS compiler makefiles: 
+   - the makefiles now use "PLATFORM" macroname with values (x64, x86, arm64)
+     instead of "CPU" macroname with values (AMD64, ARM64).
+   - the makefiles by default now use static version of the run-time library.
+
+
+18.05          2018-04-30
+-------------------------
+- The speed for LZMA/LZMA2 compressing was increased 
+    by 8% for fastest/fast compression levels and 
+    by 3% for normal/maximum compression levels.
+- Previous versions of 7-Zip could work incorrectly in "Large memory pages" mode in
+  Windows 10 because of some BUG with "Large Pages" in Windows 10. 
+  Now 7-Zip doesn't use "Large Pages" on Windows 10 up to revision 1709 (16299).
+
+
+18.03 beta     2018-03-04
+-------------------------
+- Asm\x86\LzmaDecOpt.asm: new optimized LZMA decoder written in asm 
+  for x64 with about 30% higher speed than main version of LZMA decoder written in C.
+- The speed for single-thread LZMA/LZMA2 decoder written in C was increased by 3%.
+- 7-Zip now can use multi-threading for 7z/LZMA2 decoding,
+  if there are multiple independent data chunks in LZMA2 stream.
+- 7-Zip now can use multi-threading for xz decoding,
+  if there are multiple blocks in xz stream.
+
+
+17.00 beta     2017-04-29
+-------------------------
+- NewHandler.h / NewHandler.cpp: 
+    now it redefines operator new() only for old MSVC compilers (_MSC_VER < 1900).
+- C/7zTypes.h : the names of variables in interface structures were changed (vt).
+- Some bugs were fixed. 7-Zip could crash in some cases.
+- Some internal changes in code.
+
+
+16.02          2016-05-21
+-------------------------
+- The BUG in 16.00 - 16.01 was fixed:
+  Split Handler (SplitHandler.cpp) returned incorrect 
+  total size value (kpidSize) for split archives.
+
+
+16.01          2016-05-19
+-------------------------       
+- Some bugs were fixed,
+- Some internal changes to reduce the number of compiler warnings.
+
+
+16.00          2016-05-10
+-------------------------       
+- 7-Zip now can extract multivolume ZIP archives (z01, z02, ... , zip).
+- Some bugs were fixed,
+
+
+15.12          2015-11-19
+-------------------------       
+- The BUG in C version of 7z decoder was fixed:
+  7zDec.c : SzDecodeLzma2()
+  7z decoder could mistakenly report about decoding error for some 7z archives
+  that use LZMA2 compression method.
+  The probability to get that mistaken decoding error report was about 
+  one error per 16384 solid blocks for solid blocks larger than 16 KB (compressed size). 
+- The BUG (in 9.26-15.11) in C version of 7z decoder was fixed:
+  7zArcIn.c : SzReadHeader2()
+  7z decoder worked incorrectly for 7z archives that contain 
+  empty solid blocks, that can be placed to 7z archive, if some file is 
+  unavailable for reading during archive creation.
+
+
+15.09 beta     2015-10-16
+-------------------------       
+- The BUG in LZMA / LZMA2 encoding code was fixed.
+  The BUG in LzFind.c::MatchFinder_ReadBlock() function.
+  If input data size is larger than (4 GiB - dictionary_size),
+  the following code worked incorrectly:
+  -  LZMA : LzmaEnc_MemEncode(), LzmaEncode() : LZMA encoding functions 
+     for compressing from memory to memory. 
+     That BUG is not related to LZMA encoder version that works via streams.
+  -  LZMA2 : multi-threaded version of LZMA2 encoder worked incorrectly, if 
+     default value of chunk size (CLzma2EncProps::blockSize) is changed 
+     to value larger than (4 GiB - dictionary_size).
+
+
+9.38 beta      2015-01-03
+-------------------------       
+- The BUG in 9.31-9.37 was fixed:
+  IArchiveGetRawProps interface was disabled for 7z archives.
+- The BUG in 9.26-9.36 was fixed:
+  Some code in CPP\7zip\Archive\7z\ worked correctly only under Windows.
+
+
+9.36 beta      2014-12-26
+-------------------------       
+- The BUG in command line version was fixed:
+  7-Zip created temporary archive in current folder during update archive
+  operation, if -w{Path} switch was not specified. 
+  The fixed 7-Zip creates temporary archive in folder that contains updated archive.
+- The BUG in 9.33-9.35 was fixed:
+  7-Zip silently ignored file reading errors during 7z or gz archive creation,
+  and the created archive contained only part of file that was read before error.
+  The fixed 7-Zip stops archive creation and it reports about error.
+
+
+9.31           2012-10-31
+-------------------------
+- InBuffer.h : CInBuffer  uses ISequentialInStream  *_stream; instead of CMyComPtr<ISequentialInStream> 
+  OutBuffer.h: COutBuffer uses ISequentialOutStream *_stream; instead of CMyComPtr<ISequentialOutStream> 
+        
+
+9.26           2011-04-11
+-------------------------
+- The BUG was fixed: multi-threaded ZIP stored file size that was at scan stage,
+  So if the file was changed after scan, the Unpack Size field was incorrect
+        
+
+9.21           2011-04-11
+-------------------------       
+- New class FString for file names at file systems.
+- Speed optimization in CRC code for big-endian CPUs.
+
+

+-------------------------
+- IStream.h::IOutStream::
+    STDMETHOD(SetSize)(Int64 newSize) PURE;
+  was changed to
+    STDMETHOD(SetSize)(UInt64 newSize) PURE;
+
+
+9.09           2009-12-12
+-------------------------
+- The bug was fixed:
+   Utf16_To_Utf8 funstions in UTFConvert.cpp and 7zMain.c
+   incorrectly converted surrogate characters (the code >= 0x10000) to UTF-8.
+
+
+9.05           2009-07-05
+-------------------------
+- FileMapping.h::CFileMapping now returns WRes
+
+
+9.04           2009-05-30
+-------------------------
+- ICoder.h: NCoderPropID::EEnum values were changed
+
+
+9.02           2009-04-23
+-------------------------
+- Bug was fixed: if swap2 filter was requests at compression,
+  7-zip used swap4 filter instead (but id was swap2), so archives were incorrect.
+  
+4.61           2008-11-23
+-------------------------
+- Bug in ver. 4.58+ was fixed:
+   7-Zip didn't use any -m* switch after -mtc, -mcl or -mcu for .zip archives. 
+- Bug in .CAB code was fixed. 7-Zip didn't show some empty files,
+  if .CAB archive contains more than one empty file.
+   
+
+4.59           2008-07-27
+-------------------------
+- Bug was fixed:
+   LZMA Encoder in fast compression mode could access memory outside of 
+   allocated range in some rare cases.
+   
+
+4.59 alpha     2008-05-30
+-------------------------
+- BUGS was fixed: 
+    7zOut.cpp: 7-Zip incorrectly wrote size of property records in some cases.
+    7zIn.cpp:  7-Zip incorrectly work with archive, containg archive properties.
+
+4.58 alpha 9   2008-04-29
+-------------------------
+- BUG was fixed: 7-Zip showed incorrect timestamps in ISO files.
+
+
+4.58 alpha 8   2008-04-15
+-------------------------
+- BUG in 4.58 alpha 5/6/7 was fixed:
+    LZMA encoder worked incorrectly, if lp != 0.
+- Unicode (UTF-8) support for filenames in .ZIP archives. Now there are 3 modes:
+    1) Default mode: 7-Zip uses UTF-8, if the local code page doesn't contain required symbols.
+    2) -mcu switch:  7-Zip uses UTF-8, if there are non-ASCII symbols.
+    3) -mcl switch:  7-Zip uses local code page.
+- Now it's possible to use -mSW- and -mSW+ switches instead of -mSW=off and -mSW=on  
+
+
+4.58 alpha 7   2008-04-08
+-------------------------
+- BUG was fixed: BZip2Encoder and BZip2Decoder used CEvent objects without 
+  creating, when BZip2 code was called with one thread (with -mmt1 switch or with 
+  default switches on single thread CPU).
+- .lzma support.
+- RPM and NSIS support was improved.
+- LZMA now stores only (2 << n) or (3 << n) dictionary size value to LZMA properties.
+
+
+4.58 alpha 6   2008-03-27
+-------------------------
+- NTFS time extra in ZIP.
+- New item property - kpidTimeType - VT_UI4 (0 - NTFS, 1 - Unix, 2 - DOS).
+- Static CRC table is not required now for Lzma Encoder (in Lz MatchFinder).
+
+
+4.58 alpha 5   2008-03-19
+-------------------------
+- Creation time (-mtc switch) for .7z archives
+- LZMA encoder was converted to ANSI-C
+
+
+4.58 alpha 3   2008-02-25
+-------------------------
+- Speed optimizations for LZMA decoding. Now it uses C code instead of C++.
+- 7-Zip now has 128 MB dictionary limit for 32-bit version:
+  It's for speed optimization: kNumLogBits = 9 + sizeof(size_t) / 2;
+- TAR: 'D' link flag support.
+- 7-Zip now can unpack multivolume RAR archives created with 
+  "old style volume names" scheme (-vn switch) and names *.001, *.002, ...
+- Fixed bugs:
+  - 7-Zip FM could not copy / move files to root network folders like \\COMPNAME\FOLDERNAME\
+    In case of move it removed original files.
+  - SFX-WIN: if there are errors, it still could return 0.
+  - ZIP (.XPS file) isZip64 && thisDiskNumber16 == 0xFFFF.
+  - ZIP name updating:
+      If zip file contains extra field and you try to change properties of files,
+      7-zip tries to delete all extra fileds (except for WzAES).
+      And that code could hang.
+  -  7-Zip GUI didn't suggest BZip2 dictionary size used in previous run.
+  -  If creation time stamp was included in .RAR archive, 7-zip used creation time stamp 
+     as modification time stamp.
+
+4.58 alpha 2   2007-12-31
+-------------------------
+- Small changes in Deflate and LZMA compression.
+- Some speed optimizations.
+
+
+4.57

+- Bug was fixed:
+  Anti item is created for wrong file:
