+HISTORY of the LZMA SDK\r
+-----------------------\r
+\r
+21.07 2021-12-26\r
+-------------------------\r
+- New switches: -spm and -im!{file_path} to exclude directories from processing \r
+ for specified paths that don't contain path separator character at the end of path.\r
+- The sorting order of files in archives was slightly changed to be more consistent\r
+ for cases where the name of some directory is the same as the prefix part of the name\r
+ of another directory or file.\r
+\r
+\r
+21.06 2021-11-24\r
+-------------------------\r
+- Bug in LZMA encoder in file LzmaEnc.c was fixed:\r
+ LzmaEnc_MemEncode(), LzmaEncode() and LzmaCompress() could work incorrectly, \r
+ if size value for output buffer is smaller than size required for all compressed data.\r
+ LzmaEnc_Encode() could work incorrectly,\r
+ if callback ISeqOutStream::Write() doesn't write all compressed data.\r
+ NCompress::NLzma::CEncoder::Code() could work incorrectly,\r
+ if callback ISequentialOutStream::Write() returns error code.\r
+- Bug in versions 21.00-21.05 was fixed:\r
+ 7-Zip didn't set attributes of directories during archive extracting.\r
+\r
+\r
+21.04 beta 2021-11-02\r
+-------------------------\r
+- 7-Zip now reduces the number of working CPU threads for compression,\r
+ if RAM size is not enough for compression with big LZMA2 dictionary.\r
+- 7-Zip now can create and check "file.sha256" text files that contain the list \r
+ of file names and SHA-256 checksums in format compatible with sha256sum program.\r
+\r
+\r
+21.03 beta 2021-07-20\r
+-------------------------\r

+- The speed for LZMA and LZMA2 decompression in arm64 versions for macOS and Linux \r
+ was increased by 20%-60%.\r
+\r
+\r
+21.01 alpha 2021-03-09\r
+-------------------------\r
+- The command line version of 7-Zip for Linux was released.\r
+- The improvements for speed of ARM64 version using hardware CPU instructions \r
+ for AES, CRC-32, SHA-1 and SHA-256.\r
+- Some bugs were fixed.\r
+\r
+\r
+20.02 alpha 2020-08-08\r
+-------------------------\r
+- The default number of LZMA2 chunks per solid block in 7z archive was increased to 64.\r
+ It allows to increase the compression speed for big 7z archives, if there is a big number \r
+ of CPU cores and threads.\r
+- The speed of PPMd compressing/decompressing was increased for 7z archives.\r
+- The new -ssp switch. If the switch -ssp is specified, 7-Zip doesn't allow the system \r
+ to modify "Last Access Time" property of source files for archiving and hashing operations. \r
+- Some bugs were fixed.\r
+\r
+\r
+20.00 alpha 2020-02-06\r
+-------------------------\r
+- 7-Zip now supports new optional match finders for LZMA/LZMA2 compression: bt5 and hc5, \r
+ that can work faster than bt4 and hc4 match finders for the data with big redundancy.\r
+- The compression ratio was improved for Fast and Fastest compression levels with the \r
+ following default settings:\r
+ - Fastest level (-mx1) : hc5 match finder with 256 KB dictionary.\r
+ - Fast level (-mx3) : hc5 match finder with 4 MB dictionary.\r

+ and there are minor changes in compression ratio.\r
+- Some bugs were fixed.\r
+- The bug in 7-Zip 18.02-18.05 was fixed:\r
+ There was memory leak in multithreading xz decoder - XzDecMt_Decode(),\r
+ if xz stream contains only one block.\r
+- The changes for MSVS compiler makefiles: \r
+ - the makefiles now use "PLATFORM" macroname with values (x64, x86, arm64)\r
+ instead of "CPU" macroname with values (AMD64, ARM64).\r
+ - the makefiles by default now use static version of the run-time library.\r
+\r
+\r
+18.05 2018-04-30\r
+-------------------------\r
+- The speed for LZMA/LZMA2 compressing was increased \r
+ by 8% for fastest/fast compression levels and \r
+ by 3% for normal/maximum compression levels.\r
+- Previous versions of 7-Zip could work incorrectly in "Large memory pages" mode in\r
+ Windows 10 because of some BUG with "Large Pages" in Windows 10. \r
+ Now 7-Zip doesn't use "Large Pages" on Windows 10 up to revision 1709 (16299).\r
+- The BUG was fixed in Lzma2Enc.c\r
+ Lzma2Enc_Encode2() function worked incorretly,\r
+ if (inStream == NULL) and the number of block threads is more than 1.\r
+\r
+\r

+ for x64 with about 30% higher speed than main version of LZMA decoder written in C.\r
+- The speed for single-thread LZMA/LZMA2 decoder written in C was increased by 3%.\r
+- 7-Zip now can use multi-threading for 7z/LZMA2 decoding,\r
+ if there are multiple independent data chunks in LZMA2 stream.\r
+- 7-Zip now can use multi-threading for xz decoding,\r
+ if there are multiple blocks in xz stream.\r
+\r

+ didn't work correctly for xz archives without checksum (CRC).\r
+\r
+\r

+ specified with -ms[Size]{m|g} switch.\r

+------------------------- \r
+- The BUG in C version of 7z decoder was fixed:\r
+ 7zDec.c : SzDecodeLzma2()\r
+ 7z decoder could mistakenly report about decoding error for some 7z archives\r
+ that use LZMA2 compression method.\r
+ The probability to get that mistaken decoding error report was about \r
+ one error per 16384 solid blocks for solid blocks larger than 16 KB (compressed size). \r
+- The BUG (in 9.26-15.11) in C version of 7z decoder was fixed:\r
+ 7zArcIn.c : SzReadHeader2()\r

+ unavailable for reading during archive creation.\r
+\r
+\r
+15.09 beta 2015-10-16\r

+ for compressing from memory to memory. \r
+ That BUG is not related to LZMA encoder version that works via streams.\r
+ - LZMA2 : multi-threaded version of LZMA2 encoder worked incorrectly, if \r
+ default value of chunk size (CLzma2EncProps::blockSize) is changed \r

+ 7-Zip created temporary archive in current folder during update archive\r
+ operation, if -w{Path} switch was not specified. \r
+ The fixed 7-Zip creates temporary archive in folder that contains updated archive.\r
+- The BUG in 9.33-9.35 was fixed:\r
+ 7-Zip silently ignored file reading errors during 7z or gz archive creation,\r
+ and the created archive contained only part of file that was read before error.\r
+ The fixed 7-Zip stops archive creation and it reports about error.\r
