+-----------------------
+
+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).
+- The BUG was fixed in Lzma2Enc.c
+ Lzma2Enc_Encode2() function worked incorretly,
+ if (inStream == NULL) and the number of block threads is more than 1.
+
+
+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.
+
+
+18.01 2019-01-28
+-------------------------
+- The BUG in 17.01 - 18.00 beta was fixed:
+ XzDec.c : random block unpacking and XzUnpacker_IsBlockFinished()
+ didn't work correctly for xz archives without checksum (CRC).
+
+
+18.00 beta 2019-01-10
+-------------------------
+- The BUG in xz encoder was fixed:
+ There was memory leak of 16 KB for each file compressed with
+ xz compression method, if additional filter was used.
+
+
+17.01 beta 2017-08-28
+-------------------------
+- Minor speed optimization for LZMA2 (xz and 7z) multi-threading compression.
+ 7-Zip now uses additional memory buffers for multi-block LZMA2 compression.
+ CPU utilization was slightly improved.
+- 7-zip now creates multi-block xz archives by default. Block size can be
+ specified with -ms[Size]{m|g} switch.
+- xz decoder now can unpack random block from multi-block xz archives.
+- 7-Zip command line: @listfile now doesn't work after -- switch.
+ Use -i@listfile before -- switch instead.
+- The BUGs were fixed:
+ 7-Zip 17.00 beta crashed for commands that write anti-item to 7z archive.
+
+
+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.
+
+
+16.04 2016-10-04
+-------------------------
+- The bug was fixed in DllSecur.c.
+
+
+16.03 2016-09-28
+-------------------------
+- SFX modules now use some protection against DLL preloading attack.
+- Some bugs in 7z code were fixed.
+
+
+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 internal changes to reduce the number of compiler warnings.
+
+
+16.00 2016-05-10
+-------------------------
+- 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.
+
+
