+
+**Release Day: November 15, 2024**
+
+### Important Upgrade Notes
+
+ - Docker Content Trust (DCT) for signing Docker image artifacts has been replaced by Sigstore Cosign in v10.2 (November, 2024). If you rely on artifact verification using DCT, please [transition to using Cosign](https://edu.chainguard.dev/open-source/sigstore/cosign/how-to-install-cosign/). See the [DCT deprecation Mattermost forum post](https://forum.mattermost.com/t/upcoming-dct-deprecation/19275) for more details. 
+
+```{Important}
+If you upgrade from a release earlier than v10.0, please read the other [Important Upgrade Notes](https://docs.mattermost.com/upgrade/important-upgrade-notes.html).
+```
+
+### Improvements
+
+#### User Interface (UI)
+ - Pre-packaged Calls plugin [v1.2.1](https://github.com/mattermost/mattermost-plugin-calls/releases/tag/v1.2.1).
+ - Changed the logic of ``useMilitaryTime`` to ``false`` to default to 12-hour time format unless the user's preference from ``data.Value`` is ``true``. When a notification email is sent to a user, the time should now default to the 12-hour format unless otherwise stated by the user. 
+ - A warning is now shown when deleting a post or comment from a remote/shared channel.
+ - Bot messages will now properly mention both users when they happen on non-bot Direct Messages.
+ - Updated the channel header to hide pinned posts when there aren't any in the channel.
+ - Added full support for @mentions in the values of fields in message attachments.
+
+#### Administration
+ - Added a new URL parameter called ``permanent`` to ``DELETE /api/v4/posts/<post-id>``, and set ``permanent`` to ``true`` in order to permanently delete a post and its attachments.
+ - Added Shared Channels administration page to the System Console.
+ - Added a team selector to accept connection invite flow in Shared Workspaces.
+ - Restricted activation and deactivation of LDAP-managed users through both the System Admin Console UI and Mattermost API.
+ - Export/import improvements: added the ability to export all user preferences and flagged posts.
+ - Increased timeouts to fetch cluster logs.
+ - Improved log messages for cluster communication.
+ - Information about deleted rows from the Data Retention job are now logged.
+ - License details to logs are now emitted when added or removed.
+ - Added a new mmctl command, ``mmctl post delete <post-id>``, in order to permanently delete a post and its attachments.
+
+#### Performance
+ - Added metrics to prometheus to check the mobile versions for each session daily.
+ - Improved the performance of LDAP sync jobs when group-contained teams and channels are used.
+ - Added minor improvements to notification metrics.
+ - Added minor improvements to mobile push notifications.
+
+### Bug Fixes
+ - Fixed an issue with email notifications using 24-hour timestamps by default.
+ - Fixed an issue where bots were not ignored when counting deactivated accounts for statistics.
+ - Fixed an issue where drafts didn’t allow scrolling if the user had many drafts.
+ - Fixed an issue that caused Javascript errors in the System Console.
+ - Fixed racy use of session in ``NewWebConn``.
+ - Fixed a race condition that would happen after a server start if ``EnableTesting`` was enabled.
+ - Fixed an issue where no error message was shown when replying to a deleted post from the draft screen.
+ - Fixed an issue where the check icons were missing from the Sort and Show options in the Direct Messages tab, and the Sort tab of the Channels tab.
+ - Fixed desyncing issues with unreads between the team sidebar and the title bar.
+ - Fixed an issue with message export file attachments with dedicated filestore: when the dedicated filestore is set, file attachments will be found and exported correctly.
+ - Reverted a change enforcing usernames to start with alpha characters on the server.
+ - Reverted a breaking change in ``registerSlashCommandWillBePostedHook`` that caused errors to surface in case an expected empty object was returned.
+
+### config.json
+New setting options were added to ``config.json``. Below is a list of the additions and their default values on install. The settings can be modified in ``config.json``, or the System Console when available.
+
+#### Changes to all plans:
+ - Under ``ServiceSettings`` in ``config.json``:
+    - Added a new configuration setting ``EnableAPIPostDeletion`` in order to enable/disable post deletion. This configuration setting does not need to be enabled when running mmctl in local mode.
+    - Added ``EnableDesktopLandingPage`` to allow the desktop app landing page to be disabled.
+ - Under ``NativeAppSettings`` in ``config.json``:
+     - Added a configuration setting ``MobileExternalBrowser`` that tells the Mobile app to perform SSO Authentication using the external default browser.
+
+### Go Version
+ - v10.2 is built with Go ``v1.22.6``.
+
+### Known Issues
+ - The scrollbar is not clickable when there is a "Jump to recents" toaster [MM-61526](https://mattermost.atlassian.net/browse/MM-61526).
+ - Shared Channels: Direct Messages are not supported.
+ - Searching stop words in quotation marks with Elasticsearch enabled returns more than just the searched terms.
+ - Slack import through the CLI fails if email notifications are enabled.
+ - The Playbooks left-hand sidebar doesn't update when a user is added to a run or playbook without a refresh.
+ - If a user isn't a member of a configured broadcast channel, posting a status update might fail without any error feedback. As a temporary workaround, join the configured broadcast channels, or remove those channels from the run configuration.
