Windows customers preferring moveable software program can obtain a transportable copy of the file archiver as an alternative.
The official changelog lists the next modifications and enhancements.
- The pace for LZMA/LZMA2 compressing was elevated by Three-10%,
and there are minor modifications in compression ratio.

The two principal new options in 7-Zip 18.06 are compression efficiency enhancements for the LZMA and LZMA2 compression codecs, and the fixing of a reminiscence leak within the xz decoder.
