-----------------------
+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.
