- 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.
21.00 alpha 2021-01-19
- Some internal changes in code.
- 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.

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.
- Some bugs were fixed.
