+2.1.1
+ * #1241: For the "recreate" action, actually pass the "--dry-run" flag through to Borg instead of
+   just skipping the Borg call.
+ * #1242: Fix a regression in which the "spot" check hung while collecting archive contents.
+ * #1244: When the "unsafe_skip_path_validation_before_create" option is enabled, don't log a
+   warning about it.
+ * #1245: Fix a regression in which the KeePassXC credential hook password prompt was invisible.
+ * #1246: Fix a regression in which the ntfy monitoring hook failed to send a ping when the
+   "priority" option was set.
+
+2.1.0
+ * TL;DR: Many logging, memory, and performance improvements. Mind those breaking changes!
+ * #485: When running commands (database clients, command hooks, etc.), elevate stderr output to
+   show up as borgmatic error logs.
+ * #858: With the "--log-json" flag, log borgmatic's own logs as JSON, not just Borg's.
+ * #1092: BREAKING: Treat most Borg warnings as errors by default, so for instance backups now fail
+   when source directories are missing. 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/
+ * #1092: Deprecate the "source_directories_must_exist" option, as borgmatic now treats "backup file
+   not found" warnings from Borg as errors, which accomplishes the same thing.
+ * #1132: BREAKING/SECURITY: For the Healthchecks, Apprise, Pagerduty, and Loki monitoring hooks,
+   disable log sending when not explicitly enabled. This avoids revealing private log information to
+   third-party services. To send logs anyway, set the monitoring hook's "send_logs" option to
+   "true".
+ * #1204: When verbosity levels differ between console/monitoring/syslog/file, log Borg's output to
+   each one at a different level. Previously, it was logged at the maximum level of all the
+   verbosities.
+ * #1208: Fix for the "restore" action incorrectly extracting more database dumps than the
+   "--database" flag specifies.
+ * #1210: Fix an error when running the "spot" check or "extract" action with the "progress" option
+   or "--progress" flag.
+ * #1211: Fix an error about the runtime directory getting excluded by tweaking its logic and
+   lowering the error to a warning.
+ * #1212: Fix an error when restoring multiple directory-format database dumps at once.
+ * #1213: BREAKING: Support disabling both constant and variable interpolation by escaping with
+   backslashes. For instance, interpret "\{name\}" as literally "{name}" instead of trying to
+   resolve it as a constant/variable.
+ * #1220: Cleanup snapshots immediately after ZFS, LVM, or Btrfs hooks error—rather than waiting
+   until the next time borgmatic runs.
+ * #1221: Add an "unsafe_skip_path_validation_before_create" option to skip pre-backup safety
+   validation so as to reduce backup times on large filesystems.
+ * #1224: When running an "extract" check with the "--progress" flag, show file extraction progress.
+ * #1225: Improve performance and greatly reduce memory usage during pre-backup safety validation on
+   large filesystems.
+ * #1230: Fix another warning from LVM about leaked file descriptors, this time when calling
+   "lvcreate" from a command hook.
+ * #1234: Fix for the ntfy monitoring hook erroring on emojis in the "title" option.
+ * When syslog verbosity is enabled, log to systemd's journal (if present) with
+   structured data. See the documentation for more information:
+   https://torsion.org/borgmatic/reference/command-line/logging/#systemd-journal
+ * SECURITY: Prevent shell injection attacks via constant interpolation in command hooks. (This was
+   already implemented for deprecated "before_*"/"after_*" command hooks.)
+ * Fix for an error in the "key import" action when importing a key from stdin.
+ * Fix the "recreate" action to include borgmatic-specific paths (database dumps, etc.) in recreated
+   archives.
+ * Update the "list" action to support the "--json" flag when the "--archive" flag is also used.
+ * Promote the ZFS, LVM, and Btrfs hooks from beta features to stable.
+
+2.0.13
+ * #1054: Allow the Btrfs hook to create and delete snapshots even when running
+   as a non-root user. See the documentation for more information:
+   https://torsion.org/borgmatic/reference/configuration/data-sources/btrfs/#non-root-user
+ * #1179: Add a "file_list_format" option for setting the "list" action's output format and an
+   "archive_list_format" option for setting the "repo-list" action's format.
+ * #1192: Fix for over-aggressive deduplication of source directories that contain the borgmatic
+   runtime directory, potentially resulting in data loss (data not getting backed up) when
+   snapshotting these source directories.
+ * #1192, #1163: Document potential interactions between security settings in borgmatic's sample
+   systemd service file and the ZFS, LVM, and Btrfs hooks.
+ * #1193: In the documentation for the MariaDB/MySQL database hooks, clarify how to set custom
+   command-line flags for database commands.
+ * #1193: For the MariaDB and MySQL database hooks, add a "socket_path" option for Unix socket
+   database connections.
+ * #1193: For the MariaDB and MySQL database hooks, creates a consistent snapshot by dumping all
+   tables in a single transaction.
+ * #1194: Fix for an incorrect diff command shown when running the "generate config" action with a
+   source configuration file. 
+ * #1195: Fix a regression in the ZFS, LVM, and Btrfs hooks in which snapshotted paths ignored
+   global excludes.
+ * #1201: Document a problematic interaction between borgmatic and systemd-tmpfiles:
+   https://torsion.org/borgmatic/reference/configuration/runtime-directory/#systemd-tmpfiles
+ * #1203: Fix that errors and exits when the borgmatic runtime directory is partially excluded by
+   configured excludes. Previously, borgmatic only errored when the runtime directory was completely
+   excluded.
+ * #1206: Adjust Btrfs snapshot paths so that Borg 1.x gets file cache hits when backing them up,
+   improving performance.
+ * Update the sample systemd timer with a shorter random delay when catching up on a missed run.
+
+2.0.12
+ * #1127: Fix for the database hooks not respecting the "working_directory" option.
+ * #1181: Add an "ask_for_password" option to the KeePassXC credential hook for disabling
+   KeePassXC's password prompt, e.g. if you're only using a key file to decrypt your database.
+ * #1184: Fix the fish shell completion's detection of version mismatches.
+ * #1186: Fix a regression in the Btrfs hook in which subvolume snapshots didn't get cleaned up
+   until the start of the next borgmatic run.
+ * In the SQLite database hook, run SQLite such that it exits upon encountering an error instead of,
+   you know, not doing that.
+ * Add documentation on repositories, including SSH, Rclone, S3, and B2:
+   https://torsion.org/borgmatic/reference/configuration/repositories/
+ * Improve documentation search results for individual configuration options.
+ * Add borgmatic release artifacts (wheel and tarball) to each release on the releases page:
+   https://projects.torsion.org/borgmatic-collective/borgmatic/releases
+ * Move the tarball of borgmatic's HTML documentation from the packages page to the releases page.
+
+2.0.11
+ * #957: Document borgmatic's limitations around parallelism—both its own and Borg's. See the
+   documentation for more information:
+   https://torsion.org/borgmatic/how-to/make-per-application-backups/#limitations
+ * #1165: Fix for when the systemd service directories (RuntimeDirectory and StateDirectory) each
+   contain multiple paths.
+ * #1168: Fix for the "list", "info", and "delete" options in "extra_borg_options" being ignored
+   when "--archive" is omitted with Borg 1.x.
+ * #1169: Fix for a regression in the ZFS, LVM, and Btrfs hooks in which partial excludes of
+   snapshot paths were ignored.
+ * #1170: Fix for an inconsistent log level for Borg's last output line before exiting.
+ * #1172: Add an "environment" option to the Sentry monitoring hook.
+ * #1176: Fix the "--repository" flag not applying to command hooks.
+ * Add a "rename" option to "extra_borg_options" to support passing arbitrary flags to "borg
+   rename".
+ * Add documentation on patterns and excludes:
+   https://torsion.org/borgmatic/reference/configuration/patterns-and-excludes/
+ * Drop support for Python 3.9, which has been end-of-lifed.
+
 2.0.10

    Borg sub-command that borgmatic uses. As part of this, deprecate the "init" option under
    "borg_extra_options" in favor of "repo_create".

+### Pre-backup safety validation
+
+Before running a backup during the `create` action, borgmatic automatically runs
+through some pre-backup safety validation to ensure that:
+
+1. You haven't accidentally excluded borgmatic's [runtime
+directory](https://torsion.org/borgmatic/reference/configuration/runtime-directory/)
+from the backup, which would break things like database dumps, filesystem
+snapshots, etc.
+2. Special files are auto-excluded to prevent Borg from hanging.
+
+This validation does have a cost: performance. On a large filesystem, it can
+take a while to run. So if you are absolutely sure that you aren't excluding
+borgmatic's runtime directory, and you also aren't including any special files
+that might cause Borg to hang, you can disable the pre-backup validation as
+follows:
+
+```yaml
+unsafe_skip_path_validation_before_create: true
+```
+
+However, this is indeed unsafe and could lead to hangs or data being left out
+of backups. Use this option at your own risk.

-### Shell completion
 
-borgmatic includes a shell completion script (currently only for Bash and Fish) to
-support tab-completing borgmatic command-line actions and flags. Depending on
-how you installed borgmatic, this may be enabled by default.
+### Command-line autocompletion
 
-#### Bash
+borgmatic includes autocompletion scripts for various command-line shells to
+support tab-completing command-line actions and flags. See the [autocompletion
+documentation](https://torsion.org/borgmatic/reference/command-line/autocompletion/)
+for details.
 
-If completions aren't enabled, start by installing the `bash-completion` Linux package or the
-[`bash-completion@2`](https://formulae.brew.sh/formula/bash-completion@2)
-macOS Homebrew formula. Then, install the shell completion script globally:
-
-```bash
-sudo su -c "borgmatic --bash-completion > $(pkg-config --variable=completionsdir bash-completion)/borgmatic"
-```
-
-If you don't have `pkg-config` installed, you can try the following path
-instead:
-
-```bash
-sudo su -c "borgmatic --bash-completion > /usr/share/bash-completion/completions/borgmatic"
-```
-
-Or, if you'd like to install the script for only the current user:
-
-```bash
-mkdir --parents ~/.local/share/bash-completion/completions
-borgmatic --bash-completion > ~/.local/share/bash-completion/completions/borgmatic
-```
-
-Finally, restart your shell (`exit` and open a new shell) so the completions
-take effect.
-
-#### fish
-
-To add completions for fish, install the completions file globally:
-
-```fish
-borgmatic --fish-completion | sudo tee /usr/share/fish/vendor_completions.d/borgmatic.fish
-source /usr/share/fish/vendor_completions.d/borgmatic.fish
-```
