+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.

+  and the pseudo-random number generator was improved.
+- Some bugs were fixed.
+
+
+18.06          2018-12-30
+-------------------------

+  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

+- 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
+-------------------------

+   incorrectly converted surrogate characters (the code >= 0x10000) to UTF-8.
+
+
+9.05           2009-07-05

+- 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.

+
+
+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

+  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.
