7-zip.org/history.txt

20.01 alpha 2020-08-06
– 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.
– New localization: Swahili.
