Furthermore, the software is able to open iso files and nsis installation packages. The following changes and improvements have been made in this release:

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
  to modify “Last Access Time” property of source files for archiving and hashing operations.
• Some bugs were fixed.
• New localization: Swahili.
