20.9.5 ‘Voyager’ released

· 2 min read

Changes compared to 20.9.4

Switching to use the PAX format causes spurious "PaxHeaders.0" directories to appear in current (19.00) versions of 7-Zip. This should be resolved soon by a new 7-Zip update. There is no such problem using GNU Tar or bsdtar/libarchive.


  • Perform network time sync when booting the USB Recovery Media
  • Ensure more fidelity for restoring non-ASCII filenames, atime/ctime, and timestamps with sub-second precision inside TAR archives by switching to PAX format
  • Automatically select USB device if only one is available when generating USB Recovery Media
