Mattermost 5.10.1 for GitLab 11.11
I'm opening an issue to give your team a heads up that we're preparing a dot release, 5.10.1, to fix an issue on Internet Explorer (IE11) where the system console opens a blank page.
We will prepare a merge request to GitLab omnibus in coming days, and propose it is included in an RC for GitLab 11.11.
Let me know if you have any questions.
