borgmatic 1.5.3

• #258: Stream database dumps and restores directly to/from Borg without using any additional
  filesystem space. This feature is automatic, and works even on restores from archives made with
  previous versions of borgmatic.
• #293: Documentation on macOS launchd permissions issues with work-around for Full Disk Access.
• Remove "borgmatic restore --progress" flag, as it now conflicts with streaming database restores.
