HISTORY of the 7-Zip source code
--------------------------------
21.02 alpha 2021-05-06
-------------------------
- 7-Zip now writes additional field for filename in UTF-8 encoding to zip archives.
It allows to extract correct file name from zip archives on different systems.
- The command line version of 7-Zip for macOS was released.
- The speed for LZMA and LZMA2 decompression in arm64 versions for macOS and Linux
was increased by 20%-60%.
- Some changes and improvements in ZIP, TAR and NSIS code.
21.01 alpha 2021-03-09
-------------------------
- The command line version of 7-Zip for Linux was released.
- The improvements for speed of ARM64 version using hardware CPU instructions
for AES, CRC-32, SHA-1 and SHA-256.
- The bug in versions 18.02 - 21.00 was fixed:
7-Zip could not correctly extract some ZIP archives created with xz compression method.
- Some bugs were fixed.
20.02 alpha 2020-08-08
-------------------------
- The default number of LZMA2 chunks per solid block in 7z archive was increased to 64.
It allows to increase the compression speed for big 7z archives, if there is a big number
of CPU cores and threads.
- The speed of PPMd compressing/decompressing was increased for 7z/ZIP/RAR archives.
- The new -ssp switch. If the switch -ssp is specified, 7-Zip doesn't allow the system
to modify "Last Access Time" property of source files for archiving and hashing operations.
- Some bugs were fixed.
20.00 alpha 2020-02-06
-------------------------
- 7-Zip now supports new optional match finders for LZMA/LZMA2 compression: bt5 and hc5,
that can work faster than bt4 and hc4 match finders for the data with big redundancy.
- The compression ratio was improved for Fast and Fastest compression levels with the
following default settings:
- Fastest level (-mx1) : hc5 match finder with 256 KB dictionary.
- Fast level (-mx3) : hc5 match finder with 4 MB dictionary.
- Minor speed optimizations in multithreaded LZMA/LZMA2 compression for Normal/Maximum/Ultra
compression levels.
- bzip2 decoding code was updated to support bzip2 archives, created by lbzip2 program.
19.02 2019-09-05
-------------------------
- Support for SHA-1/SHA-256 optimized code in
Sha1Opt.c, Sha256Opt.c, Sha256Opt.asm, Sha1Opt.asm.
19.00 2019-02-21
-------------------------
- Encryption strength for 7z archives was increased:
