Updated Mattermost to 4.3.4 (GitLab 10.2)
Mattermost 4.3.4 has been tested with GitLab SSO with official release on December 7 from https://about.mattermost.com/download/. We've tested it with the latest version of GitLab from the 10-2 stable branch.
Mattermost 4.3.4 contains some security fixes, so we recommend updating.
