Decompression speed of LZMA and LZMA2 archives in ARM64 versions for Mac OS and Linux improved by 20-60%.

Maximum dictionary size for LZMA/LZMA2 compression operations was increased to 4 Gigabytes.

ARM64 version speed improvements for AES, CRC-32, SHA-1 and SHA-256.

The -ssp command line switches prevents that the system modifies the 'last access time' property of source files for archiving and hashing operations.

Default number of LZMA2 chunks per solid blocks increased in 7z archives, which improves the compression speed for large 7z archives on devices with a large number of CPU cores and threads.

Improved compression ratio for fast and fastest compression levels.

ZIP AES encryption and 7z, RAR and ZIP AES decryption improved.

7-Zip supports new hardware instructions for SHA-1 and SHA-256 which new AMD Ryzen and Intel CPU's support this improves the performance of certain operations, including encrypting and decrypting ZIP AES, hash value calculations, and the speed of key derivation for encryption and decryption in 7z, ZIP and RAR archives.Support for unpacking b64 files (Base64 encoding).Here is the list of important changes when compared to the last stable version, 7-Zip 19.00:
