User Interface (UI)
Improved readability by displaying system messages on multiple lines when editing a channel header.
Combined “joined/left” event types in system messages.
Added a new user preference to disable webapp prefetching via Settings > Advanced > Allow Mattermost to prefetch channel posts. You must enable Client Performance Debugging in the System Console by going to Environment > Developer in order for this setting to appear. This setting and Client Performance Debugging should only be enabled temporarily if users are experiencing performance issues.

Pre-packaged Todo plugin version v0.7.1.
Administration
JSON null value cases are now handled correctly by also checking that the pointer is no longer null when unmarshalling to a pointer.

Known Issues
(Cloud) The About Mattermost dialog reports an incorrect server version.
Adding an @mention at the start of a post draft and pressing the left or right arrow key can clear the post draft and the undo history MM-33823.
Status may sometimes get stuck as Away or Offline in High Availability mode with IP Hash turned off.
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.
Push notifications don’t always clear on iOS when running Mattermost in High Availability mode.
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.
