• #1175: Add a "files_changed" option for customizing Borg's file modification detection.
• #1175: Add a "msgpack_version_check" option to prevent Borg from validating msgpack's version.
• #1218: Add a "config show" action to display computed borgmatic configuration as YAML or JSON,
  handy for fetching borgmatic configuration from external scripts. See the documentation for more
  information:
  https://torsion.org/borgmatic/reference/command-line/actions/config-show/
• #1228: Adjust the "spot" check so error output includes more information about what failed.
• #1236: Fix the "spot" check to skip hard links, as Borg doesn't produces hashes for them.
• #1243: Add a "diff" action for viewing the difference between the contents of two archives.
• #1248: Go back to treating Borg "file not found" warnings (exit code 107) as
  warnings instead of errors. Otherwise, borgmatic can error on files that a user intentionally
  deletes while a backup is running. You can still override this behavior with the
  "borg_exit_codes" option. See the documentation for more information:
  https://torsion.org/borgmatic/how-to/customize-warnings-and-errors/
• #1248: Un-deprecate the "source_directories_must_exist" option and default it to true, to
  compensate for Borg "file not found" warnings no longer being treated as errors.
• #1269: Fix the ZFS hook to support datasets with a "canmount" property of "noauto".
• #1270: Follow symlinks when backing up borgmatic configuration files to support the "bootstrap"
  action.
• #1274: Add an optional override for the documentation development listen port and use Podman
  Compose if present.
• #1281: Fix a unicode error when backing up a non-UTF-8 source filename with a
  corresponding system locale.
• Add a policy about the use of generative AI in the borgmatic codebase:
