+Sources history of the 7-Zip
+----------------------------
+
+9.18 2010-11-02
+-------------------------
+- New small SFX module for installers (C/Util/SfxSetup).
+
+
+9.17 2010-10-04
+-------------------------
+- 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
+----

+
+
+4.45 beta 2007-04-16
+-------------------------
+- 7-Zip now uses C version of CRC, so you must call CrcGenerateTable at
+ stratup code, or you must add CPP/Common/CRC.cpp to your project.

+- Open error messages
+- unRar 1.5 fixed
+- unShrink fixed

+ 7-Zip compressing to .zip in multi-threading mode didn't work in some cases.
+
+
+4.44 beta 2007-01-20
+-------------------------
+
+- Bug was fixed: LZMAEncoder.cpp::CEncoder::GetOptimumFast
+ it was:
+ data++
+ fixed version:
+ data = _matchFinder.GetPointerToCurrentPos(_matchFinderObj) - 1;
+ It could lead to very small cpmpression ratio decreasing when block needs move.
