What’s new after 7-Zip 20.00 alpha:

• 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
