• #541: Add "borgmatic list --find" flag for searching for files across multiple archives, useful
  for hunting down that file you accidentally deleted so you can extract it. See the documentation
  for more information:
  https://torsion.org/borgmatic/docs/how-to/inspect-your-backups/#searching-for-a-file
• #543: Add a monitoring hook for sending push notifications via ntfy. See the documentation for
  more information: https://torsion.org/borgmatic/docs/how-to/monitor-your-backups/#ntfy-hook
• Fix Bash completion script to no longer alter your shell's settings (complain about unset
  variables or error on pipe failures).
• Deprecate "borgmatic list --successful" flag, as listing only non-checkpoint (successful)
  archives is now the default in newer versions of Borg.
