@@ -98,3 +98,70 @@ functioning of the bzip2 program or library.  Added a couple of casts
 so the library compiles without warnings at level 3 in MS Visual
 Studio 6.0.  Included a Y2K statement in the file Y2K_INFO.  All other
 changes are minor documentation changes.

+1.0
+~~~
+Several minor bugfixes and enhancements:
+
+* Large file support.  The library uses 64-bit counters to
+  count the volume of data passing through it.  bzip2.c 
+  is now compiled with -D_FILE_OFFSET_BITS=64 to get large
+  file support from the C library.  -v correctly prints out
+  file sizes greater than 4 gigabytes.  All these changes have
+  been made without assuming a 64-bit platform or a C compiler
+  which supports 64-bit ints, so, except for the C library
+  aspect, they are fully portable.
+
+* Decompression robustness.  The library/program should be
+  robust to any corruption of compressed data, detecting and
+  handling _all_ corruption, instead of merely relying on
+  the CRCs.  What this means is that the program should 
+  never crash, given corrupted data, and the library should
+  always return BZ_DATA_ERROR.
+
+* Fixed an obscure race-condition bug only ever observed on
+  Solaris, in which, if you were very unlucky and issued
+  control-C at exactly the wrong time, both input and output
+  files would be deleted.
+
+* Don't run out of file handles on test/decompression when
+  large numbers of files have invalid magic numbers.
+
+* Avoid library namespace pollution.  Prefix all exported 
+  symbols with BZ2_.
+
+* Minor sorting enhancements from my DCC2000 paper.
+
+* Advance the version number to 1.0, so as to counteract the
+  (false-in-this-case) impression some people have that programs 
+  with version numbers less than 1.0 are in someway, experimental,
+  pre-release versions.
+
+* Create an initial Makefile-libbz2_so to build a shared library.
+  Yes, I know I should really use libtool et al ...
+
+* Make the program exit with 2 instead of 0 when decompression
+  fails due to a bad magic number (ie, an invalid bzip2 header).
+  Also exit with 1 (as the manual claims :-) whenever a diagnostic
+  message would have been printed AND the corresponding operation 
+  is aborted, for example
+     bzip2: Output file xx already exists.
+  When a diagnostic message is printed but the operation is not 
+  aborted, for example
+     bzip2: Can't guess original name for wurble -- using wurble.out
+  then the exit value 0 is returned, unless some other problem is
+  also detected.
+
+  I think it corresponds more closely to what the manual claims now.
+
+
+1.0.1
+~~~~~
+* Modified dlltest.c so it uses the new BZ2_ naming scheme.
+* Modified makefile-msc to fix minor build probs on Win2k.
+* Updated README.COMPILATION.PROBLEMS.
+
+There are no functionality changes or bug fixes relative to version
+1.0.0.  This is just a documentation update + a fix for minor Win32
+build problems.  For almost everyone, upgrading from 1.0.0 to 1.0.1 is
+utterly pointless.  Don't bother.
