Update GitLab Mattermost to 3.6.7 in 8.17
Backporting a number of security fixes from our latest release to Mattermost version 3.6.7. Please note:
- The Site URL setting is now required for email notifications and email invitations. Existing installs without the Site URL specified will upgrade successfully but the System Admin will see a header bar notification until the setting is specified in the
gitlab.rb
. Please see the open issue to mapmattermost_external_url
toServiceSettings.SiteURL
.
See details in the Changelog. Please let me know if you have any questions or concerns.
