Right here is the record of vital adjustments when in comparison with the final steady model, 7-Zip 19.00:

Help for unpacking b64 recordsdata (Base64 encoding).
7-Zip helps new {hardware} directions for SHA-1 and SHA-256 which new AMD Ryzen and Intel CPU’s help; this improves the efficiency of sure operations, together with encrypting and decrypting ZIP AES, hash worth calculations, and the pace of key derivation for encryption and decryption in 7z, ZIP and RAR archives.
ZIP AES encryption and 7z, RAR and ZIP AES decryption improved.
Improved compression ratio for quick and quickest compression ranges.
Default variety of LZMA2 chunks per stable blocks elevated in 7z archives, which improves the compression pace for giant 7z archives on gadgets with a lot of CPU cores and threads.
The -ssp command line switches prevents that the system modifies the “final entry time” property of supply recordsdata for archiving and hashing operations.
ARM64 model pace enhancements for AES, CRC-32, SHA-1 and SHA-256.
Most dictionary dimension for LZMA/LZMA2 compression operations was elevated to 4 Gigabytes.
Decompression pace of LZMA and LZMA2 archives in ARM64 variations for Mac OS and Linux improved by 20-60%.
7-Zip writes a further subject for the filename in UTF-8 encoding in ZIP archives.
The variety of working CPU threads is eliminated for compression if the RAM dimension isn’t sufficient for compression operations with massive LZMA2 dictionaries.
