Bump version for release.

Fix end-to-end tests (#1072 ).
If the exact same "everything" command hook is present in multiple configuration files, borgmatic only runs it once (#1080 ).

+2.0.4
+ * #1072: Fix path rewriting for non-root patterns in the ZFS, Btrfs, and LVM hooks.
+ * #1073: Clarify the documentation about when an "after: error" command hook runs and how it
+   differs from other hooks:
+   https://torsion.org/borgmatic/docs/how-to/add-preparation-and-cleanup-steps-to-backups/
+ * #1075: Fix an incorrect warning about Borg placeholders being unsupported in a command hook.
+ * #1080: If the exact same "everything" command hook is present in multiple configuration files,
+   only run it once.
+
+2.0.3
+ * #1065: Fix a regression in monitoring hooks in which an error pinged the finish state instead of
+   the fail state.
+ * #1066: Add a "states" option to command hooks, so you can optionally skip an "after" hook if
+   borgmatic encounters an error.
+ * #1071: Fix an error in the LVM hook when removing a snapshot directory.
+
+2.0.2
+ * #1035: Document potential performance issues and workarounds with the ZFS, Btrfs, and LVM hooks:
+   https://torsion.org/borgmatic/docs/how-to/snapshot-your-filesystems/
+ * #1053: Display a nicer error message when the "recreate" action encounters an archive that
+   already exists.
+ * #1059: Fix a regression in which soft failure exit codes in command hooks were not respected.
+ * #1060: Fix action command hooks getting run too many times when multiple borgmatic actions are
+   executed (implicitly or explicitly).
+ * #1060: Don't run action command hooks for actions listed in the "skip_actions" option.
+ * #1062: Fix a regression that broke environment variable interpolation.
+ * #1063: List the configured "when" action names in the log entries for command hooks.
+
+2.0.1
+ * #1057: Fix argument parsing to avoid using Python 3.12+ string features. Now borgmatic will
+   work with Python 3.9, 3.10, and 3.11 again.
+
+2.0.0
+ * TL;DR: More flexible, completely revamped command hooks. All configuration options settable on
+   the command-line. New configuration options for many command-line flags (including verbosity!).
+   New "key import" and "recreate" actions. Almost everything is backwards compatible—but mind those
+   deprecation warnings!
+ * #262: Add a "default_actions" option that supports disabling default actions when borgmatic is
+   run without any command-line arguments.
+ * #303: Deprecate the "--override" flag in favor of direct command-line flags for every borgmatic
+   configuration option. See the documentation for more information:
+   https://torsion.org/borgmatic/docs/how-to/make-per-application-backups/#configuration-overrides
+ * #303: Add configuration options that serve as defaults for some (but not all) command-line
+   action flags. For example, each entry in "repositories:" now has an "encryption" option that
+   applies to the "repo-create" action, serving as a default for the "--encryption" flag. See the
+   documentation for more information: https://torsion.org/borgmatic/docs/reference/configuration/
+ * #345: Add a "key import" action to import a repository key from backup.
+ * #422: Add home directory expansion to file-based and KeePassXC credential hooks.
+ * #610: Add a "recreate" action for recreating archives, for instance for retroactively excluding
+   particular files from existing archives.
+ * #790, #821: Deprecate all "before_*", "after_*" and "on_error" command hooks in favor of more
+   flexible "commands:". See the documentation for more information:
+   https://torsion.org/borgmatic/docs/how-to/add-preparation-and-cleanup-steps-to-backups/
+ * #790: BREAKING: For both new and deprecated command hooks, run a configured "after" hook even if
+   an error occurs first. This allows you to perform cleanup steps that correspond to "before"
+   preparation commands—even when something goes wrong.
+ * #790: BREAKING: Run all command hooks (both new and deprecated) respecting the
+   "working_directory" option if configured, meaning that hook commands are run in that directory.
+ * #793: Add configuration options for all verbosity and logging flags, so you don't have to set
+   them on the command-line.
+ * #836: Add a custom command option for the SQLite hook.
+ * #837: Add custom command options for the MongoDB hook.
+ * #1010: When using Borg 2, don't pass the "--stats" flag to "borg prune".
+ * #1020: Document a database use case involving a temporary database client container:
+   https://torsion.org/borgmatic/docs/how-to/backup-your-databases/#containers
+ * #1037: Fix an error with the "extract" action when both a remote repository and a
+   "working_directory" are used.
+ * #1044: Fix an error in the systemd credential hook when the credential name contains a "."
+   character.
+ * #1047: Add "key-file" and "yubikey" options to the KeePassXC credential hook.
+ * #1048: Fix a "no such file or directory" error in ZFS, Btrfs, and LVM hooks with nested
+   directories that reside on separate devices/filesystems.
+ * #1050: Fix a failure in the "spot" check when the archive contains a symlink.
+ * #1051: Add configuration filename to the "Successfully ran configuration file" log message.
+
+1.9.14
+ * #409: With the PagerDuty monitoring hook, send borgmatic logs to PagerDuty so they show up in the
+   incident UI. See the documentation for more information:
+   https://torsion.org/borgmatic/docs/how-to/monitor-your-backups/#pagerduty-hook
+ * #936: Clarify Zabbix monitoring hook documentation about creating items:
+   https://torsion.org/borgmatic/docs/how-to/monitor-your-backups/#zabbix-hook
+ * #1017: Fix a regression in which some MariaDB/MySQL passwords were not escaped correctly.
+ * #1021: Fix a regression in which the "exclude_patterns" option didn't expand "~" (the user's
+   home directory). This fix means that all "patterns" and "patterns_from" also now expand "~".
+ * #1023: Fix an error in the Btrfs hook when attempting to snapshot a read-only subvolume. Now,
+   read-only subvolumes are ignored since Btrfs can't actually snapshot them.
+
+1.9.13
+ * #975: Add a "compression" option to the PostgreSQL database hook.
+ * #1001: Fix a ZFS error during snapshot cleanup.
+ * #1003: In the Zabbix monitoring hook, support Zabbix 7.2's authentication changes.
+ * #1009: Send database passwords to MariaDB and MySQL via anonymous pipe, which is more secure than
+   using an environment variable.
+ * #1013: Send database passwords to MongoDB via anonymous pipe, which is more secure than using
+   "--password" on the command-line!
+ * #1015: When ctrl-C is pressed, more strongly encourage Borg to actually exit.
+ * Add a "verify_tls" option to the Uptime Kuma monitoring hook for disabling TLS verification.
+ * Add "tls" options to the MariaDB and MySQL database hooks to enable or disable TLS encryption
+   between client and server.
+
+1.9.12
+ * #1005: Fix the credential hooks to avoid using Python 3.12+ string features. Now borgmatic will
+   work with Python 3.9, 3.10, and 3.11 again.
+
+1.9.11
+ * #795: Add credential loading from file, KeePassXC, and Docker/Podman secrets. See the
+   documentation for more information:
+   https://torsion.org/borgmatic/docs/how-to/provide-your-passwords/
+ * #996: Fix the "create" action to omit the repository label prefix from Borg's output when
+   databases are enabled.
+ * #998: Send the "encryption_passphrase" option to Borg via an anonymous pipe, which is more secure
+   than using an environment variable.
+ * #999: Fix a runtime directory error from a conflict between "extra_borg_options" and special file
+   detection.
+ * #1001: For the ZFS, Btrfs, and LVM hooks, only make snapshots for root patterns that come from
+   a borgmatic configuration option (e.g. "source_directories")—not from other hooks within
+   borgmatic.
+ * #1001: Fix a ZFS/LVM error due to colliding snapshot mount points for nested datasets or logical
+   volumes.
+ * #1001: Don't try to snapshot ZFS datasets that have the "canmount=off" property.
+ * Fix another error in the Btrfs hook when a subvolume mounted at "/" is configured in borgmatic's
+   source directories.
+
+1.9.10
+ * #966: Add a "{credential ...}" syntax for loading systemd credentials into borgmatic
+   configuration files. See the documentation for more information:
+   https://torsion.org/borgmatic/docs/how-to/provide-your-passwords/
+ * #987: Fix a "list" action error when the "encryption_passcommand" option is set.
+ * #987: When both "encryption_passcommand" and "encryption_passphrase" are configured, prefer
+   "encryption_passphrase" even if it's an empty value.
+ * #988: With the "max_duration" option or the "--max-duration" flag, run the archives and
+   repository checks separately so they don't interfere with one another. Previously, borgmatic
+   refused to run checks in this situation.
+ * #989: Fix the log message code to avoid using Python 3.10+ logging features. Now borgmatic will
+   work with Python 3.9 again.
+ * Capture and delay any log records produced before logging is fully configured, so early log
+   records don't get lost.
+ * Add support for Python 3.13.
+
+1.9.9
+ * #635: Log the repository path or label on every relevant log message, not just some logs.
+ * #961: When the "encryption_passcommand" option is set, call the command once from borgmatic to
+   collect the encryption passphrase and then pass it to Borg multiple times. See the documentation
+   for more information: https://torsion.org/borgmatic/docs/how-to/provide-your-passwords/
+ * #981: Fix a "spot" check file count delta error.
+ * #982: Fix for borgmatic "exclude_patterns" and "exclude_from" recursing into excluded
+   subdirectories.
+ * #983: Fix the Btrfs hook to support subvolumes with names like "@home" different from their
+   mount points.
+ * #985: Change the default value for the "--original-hostname" flag from "localhost" to no host
+   specified. This way, the "restore" action works without a hostname if there's a single matching
+   database dump.
+
+1.9.8
+ * #979: Fix root patterns so they don't have an invalid "sh:" prefix before getting passed to Borg.
+ * Expand the recent contributors documentation section to include ticket submitters—not just code
+   contributors—because there are multiple ways to contribute to the project! See:
+   https://torsion.org/borgmatic/#recent-contributors
+
+1.9.7
+ * #855: Add a Sentry monitoring hook. See the documentation for more information:
+   https://torsion.org/borgmatic/docs/how-to/monitor-your-backups/#sentry-hook
+ * #968: Fix for a "spot" check error when a filename in the most recent archive contains a newline.
+ * #970: Fix for an error when there's a blank line in the configured patterns or excludes.
+ * #971: Fix for "exclude_from" files being completely ignored.
+ * #977: Fix for "exclude_patterns" and "exclude_from" not supporting explicit pattern styles (e.g.,
+   "sh:" or "re:").
+
+1.9.6
+ * #959: Fix an error in the Btrfs hook when a subvolume mounted at "/" is configured in borgmatic's
+   source directories.
+ * #960: Fix for archives storing relative source directory paths such that they contain the working
+   directory.
+ * #960: Fix the "spot" check to support relative source directory paths.
+ * #962: For the ZFS, Btrfs, and LVM hooks, perform path rewriting for excludes and patterns in
+   addition to the existing source directories rewriting.
+ * #962: Under the hood, merge all configured source directories, excludes, and patterns into a
+   unified temporary patterns file for passing to Borg. The borgmatic configuration options remain
+   unchanged.
+ * #962: For the LVM hook, add support for nested logical volumes.
+ * #965: Fix a borgmatic runtime directory error when running the "spot" check with a database hook
+   enabled.
+ * #969: Fix the "restore" action to work on database dumps without a port when a default port is
+   present in configuration.
+ * Fix the "spot" check to no longer consider pipe files within an archive for file comparisons.
+ * Fix the "spot" check to have a nicer error when there are no source paths to compare.
+ * Fix auto-excluding of special files (when databases are configured) to support relative source
+   directory paths.
+ * Drop support for Python 3.8, which has been end-of-lifed.
+
+1.9.5
+ * #418: Backup and restore databases that have the same name but with different ports, hostnames,
+   or hooks.
+ * #947: To avoid a hang in the database hooks, error and exit when the borgmatic runtime
+   directory overlaps with the configured excludes.
+ * #954: Fix a findmnt command error in the Btrfs hook by switching to parsing JSON output.
+ * #956: Fix the printing of a color reset code even when color is disabled.
+ * #958: Drop colorama as a library dependency.
+ * When the ZFS, Btrfs, or LVM hooks aren't configured, don't try to cleanup snapshots for them.
+
+1.9.4
+ * #80 (beta): Add an LVM hook for snapshotting and backing up LVM logical volumes. See the
+   documentation for more information:
+   https://torsion.org/borgmatic/docs/how-to/snapshot-your-filesystems/
+ * #251 (beta): Add a Btrfs hook for snapshotting and backing up Btrfs subvolumes. See the
+   documentation for more information:
+   https://torsion.org/borgmatic/docs/how-to/snapshot-your-filesystems/
+ * #926: Fix a library error when running within a PyInstaller bundle.
+ * #950: Fix a snapshot unmount error in the ZFS hook when using nested datasets.
+ * Update the ZFS hook to discover and snapshot ZFS datasets even if they are parent/grandparent
+   directories of your source directories.
+ * Reorganize data source and monitoring hooks to make developing new hooks easier.
+
+1.9.3
+ * #261 (beta): Add a ZFS hook for snapshotting and backing up ZFS datasets. See the documentation
+   for more information: https://torsion.org/borgmatic/docs/how-to/snapshot-your-filesystems/
+ * Remove any temporary copies of the manifest file created in support of the "bootstrap" action.
+ * Deprecate the "store_config_files" option at the global scope and move it under the "bootstrap"
+   hook. See the documentation for more information:
+   https://torsion.org/borgmatic/docs/how-to/extract-a-backup/#extract-the-configuration-files-used-to-create-an-archive
+ * Require the runtime directory to be an absolute path.
+ * Add a "--deleted" flag to the "repo-list" action for listing deleted archives that haven't
+   yet been compacted (Borg 2 only).
+ * Promote the "spot" check from a beta feature to stable.
+
+1.9.2
+ * #441: Apply the "umask" option to all relevant actions, not just some of them.
+ * #722: Remove the restriction that the "extract" and "mount" actions must match a single
+   repository. Now they work more like other actions, where each repository is applied in turn.
+ * #932: Fix the missing build backend setting in pyproject.toml to allow Fedora builds.
+ * #934: Update the logic that probes for the borgmatic streaming database dump, bootstrap
+   metadata, and check state directories to support more platforms and use cases. See the
+   documentation for more information:
+   https://torsion.org/borgmatic/docs/how-to/backup-your-databases/#runtime-directory
+ * #934: Add the "RuntimeDirectory" and "StateDirectory" options to the sample systemd service
+   file to support the new runtime and state directory logic.
+ * #939: Fix borgmatic ignoring the "BORG_RELOCATED_REPO_ACCESS_IS_OK" and
+   "BORG_UNKNOWN_UNENCRYPTED_REPO_ACCESS_IS_OK" environment variables.
+ * Add a Pushover monitoring hook. See the documentation for more information:
+   https://torsion.org/borgmatic/docs/how-to/monitor-your-backups/#pushover-hook
+
+1.9.1
+ * #928: Fix the user runtime directory location on macOS (and possibly Cygwin).
+ * #930: Fix an error with the sample systemd service when no credentials are configured.
+ * #931: Fix an error when implicitly upgrading the check state directory from ~/.borgmatic to
+   ~/.local/state/borgmatic across filesystems.
+
+1.9.0
+ * #609: Fix the glob expansion of "source_directories" values to respect the "working_directory"
+   option.
+ * #609: BREAKING: Apply the "working_directory" option to all actions, not just "create". This
+   includes repository paths, destination paths, mount points, etc.
+ * #562: Deprecate the "borgmatic_source_directory" option in favor of "user_runtime_directory"
+   and "user_state_directory".
+ * #562: BREAKING: Move the default borgmatic streaming database dump and bootstrap metadata
+   directory from ~/.borgmatic to /run/user/$UID/borgmatic, which is more XDG-compliant. You can
+   override this location with the new "user_runtime_directory" option. Existing archives with
+   database dumps at the old location are still restorable. 
+ * #562, #638: Move the default check state directory from ~/.borgmatic to 
+   ~/.local/state/borgmatic. This is more XDG-compliant and also prevents these state files from
+   getting backed up (unless you explicitly include them). You can override this location with the
+   new "user_state_directory" option. After the first time you run the "check" action with borgmatic
+   1.9.0, you can safely delete the ~/.borgmatic directory.
+ * #838: BREAKING: With Borg 1.4+, store database dumps and bootstrap metadata in a "/borgmatic"
+   directory within a backup archive, so the path doesn't depend on the current user. This means
+   that you can now backup as one user and restore or bootstrap as another user, among other use
+   cases.
+ * #902: Add loading of encrypted systemd credentials. See the documentation for more information:
+   https://torsion.org/borgmatic/docs/how-to/provide-your-passwords/#using-systemd-service-credentials
+ * #911: Add a "key change-passphrase" action to change the passphrase protecting a repository key.
+ * #914: Fix a confusing apparent hang when when the repository location changes, and instead
+   show a helpful error message.
+ * #915: BREAKING: Rename repository actions like "rcreate" to more explicit names like
+   "repo-create" for compatibility with recent changes in Borg 2.0.0b10.
+ * #918: BREAKING: When databases are configured, don't auto-enable the "one_file_system" option,
+   as existing auto-excludes of special files should be sufficient to prevent Borg from hanging on
+   them. But if this change causes problems for you, you can always enable "one_file_system"
+   explicitly.
+ * #919: Clarify the command-line help for the "--config" flag.
+ * #919: Document a policy for versioning and breaking changes:
+   https://torsion.org/borgmatic/docs/how-to/upgrade/#versioning-and-breaking-changes
+ * #921: BREAKING: Change soft failure command hooks to skip only the current repository rather than
+   all repositories in the configuration file.
+ * #922: Replace setup.py (Python packaging metadata) with the more modern pyproject.toml.
+ * When using Borg 2, default the "archive_name_format" option to just "{hostname}", as Borg 2 does
+   not require unique archive names; identical archive names form a common "series" that can be
+   targeted together. See the Borg 2 documentation for more information:
+   https://borgbackup.readthedocs.io/en/2.0.0b13/changes.html#borg-1-2-x-1-4-x-to-borg-2-0
+ * Add support for Borg 2's "rclone:" repository URLs, so you can backup to 70+ cloud storage
+   services whether or not they support Borg explicitly.
+ * Add support for Borg 2's "sftp://" repository URLs.
+ * Update the "--match-archives" and "--archive" flags to support Borg 2 series names or archive
+   hashes.
+ * Add a "--match-archives" flag to the "prune" action.
+ * Add "--local-path" and "--remote-path" flags to the "config bootstrap" action for setting the
+   Borg executable paths used for bootstrapping.
+ * Add a "--user-runtime-directory" flag to the "config bootstrap" action for helping borgmatic
+   locate the bootstrap metadata stored in an archive.
+ * Add a Zabbix monitoring hook. See the documentation for more information:
+   https://torsion.org/borgmatic/docs/how-to/monitor-your-backups/#zabbix-hook
+ * Add a tarball of borgmatic's HTML documentation to the packages on the project page.
+
+1.8.14
+ * #896: Fix an error in borgmatic rcreate/init on an empty repository directory with Borg 1.4.
+ * #898: Add glob ("*") support to the "--repository" flag. Just quote any values containing

+ * #785: Add an "only_run_on" option to consistency checks so you can limit a check to running on
+   particular days of the week. See the documentation for more information:

+ * #886: Fix a PagerDuty hook traceback with Python < 3.10.
+ * #889: Fix the Healthchecks ping body size limit, restoring it to the documented 100,000 bytes.
+
+1.8.12
+ * #817: Add a "--max-duration" flag to the "check" action and a "max_duration" option to the
+   repository check configuration. This tells Borg to interrupt a repository check after a certain
+   duration.
+ * #860: Fix interaction between environment variable interpolation in constants and shell escaping.

+ * #857: Fix a traceback with "check --only spot" when the "spot" check is unconfigured.
+
+1.8.10
+ * #656 (beta): Add a "spot" consistency check that compares file counts and contents between your
+   source files and the latest archive, ensuring they fall within configured tolerances. This can
+   catch problems like incorrect excludes, inadvertent deletes, files changed by malware, etc. See
+   the documentation for more information:
+   https://torsion.org/borgmatic/docs/how-to/deal-with-very-large-backups/#spot-check

+ * #848: SECURITY: Mask the password when logging a MongoDB dump or restore command.
+ * Fix handling of the NO_COLOR environment variable to ignore an empty value.
+ * Add documentation about backing up containerized databases by configuring borgmatic to exec into
+   a container to run a dump command:
+   https://torsion.org/borgmatic/docs/how-to/backup-your-databases/#containers
+
+1.8.9
+ * #311: Add custom dump/restore command options for MySQL and MariaDB.
+ * #811: Add an "access_token" option to the ntfy monitoring hook for authenticating
+   without username/password.
+ * #827: When the "--json" flag is given, suppress console escape codes so as not to
+   interfere with JSON output.
+ * #829: Fix "--override" values containing deprecated section headers not actually overriding
+   configuration options under deprecated section headers.
+ * #835: Add support for the NO_COLOR environment variable. See the documentation for more
+   information:
+   https://torsion.org/borgmatic/docs/how-to/set-up-backups/#colored-output
+ * #839: Add log sending for the Apprise logging hook, enabled by default. See the documentation for
+   more information:
+   https://torsion.org/borgmatic/docs/how-to/monitor-your-backups/#apprise-hook
+ * #839: Document a potentially breaking shell quoting edge case within error hooks:
+   https://torsion.org/borgmatic/docs/how-to/monitor-your-backups/#error-hooks
+ * #840: When running the "rcreate" action and the repository already exists but with a different
+   encryption mode than requested, error.
+ * Switch from Drone to Gitea Actions for continuous integration.
+ * Rename scripts/run-end-to-end-dev-tests to scripts/run-end-to-end-tests and use it in both dev
+   and CI for better dev-CI parity.
+ * Clarify documentation about restoring a database: borgmatic does not create the database upon
+   restore.
+
+1.8.8
+ * #370: For the PostgreSQL hook, pass the "PGSSLMODE" environment variable through to Borg when the
+   database's configuration omits the "ssl_mode" option.
+ * #818: Allow the "--repository" flag to match across multiple configuration files.
+ * #820: Fix broken repository detection in the "rcreate" action with Borg 1.4. The issue did not
+   occur with other versions of Borg.
+ * #822: Fix broken escaping logic in the PostgreSQL hook's "pg_dump_command" option.
+ * SECURITY: Prevent additional shell injection attacks within the PostgreSQL hook.
+
+1.8.7
+ * #736: Store included configuration files within each backup archive in support of the "config
+   bootstrap" action. Previously, only top-level configuration files were stored.
+ * #798: Elevate specific Borg warnings to errors or squash errors to
+ * warnings. See the documentation for more information:
+   https://torsion.org/borgmatic/docs/how-to/customize-warnings-and-errors/
+ * #810: SECURITY: Prevent shell injection attacks within the PostgreSQL hook, the MongoDB hook, the
+   SQLite hook, the "borgmatic borg" action, and command hook variable/constant interpolation.
+ * #814: Fix a traceback when providing an invalid "--override" value for a list option.
+
+1.8.6
+ * #767: Add an "--ssh-command" flag to the "config bootstrap" action for setting a custom SSH
+   command, as no configuration is available (including the "ssh_command" option) until
+   bootstrapping completes.
+ * #794: Fix a traceback when the "repositories" option contains both strings and key/value pairs.
+ * #800: Add configured repository labels to the JSON output for all actions.
+ * #802: The "check --force" flag now runs checks even if "check" is in "skip_actions".
+ * #804: Validate the configured action names in the "skip_actions" option.
+ * #807: Stream SQLite databases directly to Borg instead of dumping to an intermediate file.
+ * When logging commands that borgmatic executes, log the environment variables that
+   borgmatic sets for those commands. (But don't log their values, since they often contain
+   passwords.)
+
+1.8.5
+ * #701: Add a "skip_actions" option to skip running particular actions, handy for append-only or
+   checkless configurations. See the documentation for more information:
+   https://torsion.org/borgmatic/docs/how-to/set-up-backups/#skipping-actions
+ * #701: Deprecate the "disabled" value for the "checks" option in favor of the new "skip_actions"
+   option.
+ * #745: Constants now apply to included configuration, not just the file doing the includes. As a
+   side effect of this change, constants no longer apply to option names and only substitute into
+   configuration values.
+ * #779: Add a "--match-archives" flag to the "check" action for selecting the archives to check,
+   overriding the existing "archive_name_format" and "match_archives" options in configuration.
+ * #779: Only parse "--override" values as complex data types when they're for options of those
+   types.
+ * #782: Fix environment variable interpolation within configured repository paths.
+ * #782: Add configuration constant overriding via the existing "--override" flag.
+ * #783: Upgrade ruamel.yaml dependency to support version 0.18.x.
+ * #784: Drop support for Python 3.7, which has been end-of-lifed.
+
+1.8.4
+ * #715: Add a monitoring hook for sending backup status to a variety of monitoring services via the
+   Apprise library. See the documentation for more information:
+   https://torsion.org/borgmatic/docs/how-to/monitor-your-backups/#apprise-hook
+ * #748: When an archive filter causes no matching archives for the "rlist" or "info"
+   actions, warn the user and suggest how to remove the filter.
+ * #768: Fix a traceback when an invalid command-line flag or action is used.
+ * #771: Fix normalization of deprecated sections ("location:", "storage:", "hooks:", etc.) to
+   support empty sections without erroring.
+ * #774: Disallow the "--dry-run" flag with the "borg" action, as borgmatic can't guarantee the Borg
+   command won't have side effects.
+
+1.8.3
+ * #665: BREAKING: Simplify logging logic as follows: Syslog verbosity is now disabled by
+   default, but setting the "--syslog-verbosity" flag enables it regardless of whether you're at an
+   interactive console. Additionally, "--log-file-verbosity" and "--monitoring-verbosity" now
+   default to 1 (info about steps borgmatic is taking) instead of 0. And both syslog logging and
+   file logging can be enabled simultaneously.
+ * #743: Add a monitoring hook for sending backup status and logs to Grafana Loki. See the
+   documentation for more information:
+   https://torsion.org/borgmatic/docs/how-to/monitor-your-backups/#loki-hook
+ * #753: When "archive_name_format" is not set, filter archives using the default archive name
+   format.
+ * #754: Fix error handling to log command output as one record per line instead of truncating
+   too-long output and swallowing the end of some Borg error messages.
+ * #757: Update documentation so "sudo borgmatic" works for pipx borgmatic installations.
+ * #761: Fix for borgmatic not stopping Borg immediately when the user presses ctrl-C.
+ * Update documentation to recommend installing/upgrading borgmatic with pipx instead of pip. See the
+   documentation for more information:

+

+    set outside borgmatic; configured options should take precedence. Second, when borgmatic gets a
