Mattermost and gitlab are driving me crazy

Suppose I want to upgrade from 8.8 to 8.9.x of gitlab, is that working yet? It seems it always breaks if you have mattermost enabled. I am in a VM so I can at least revert, but when oh when will it be possible to update to 8.9 of gitlab (and 3.0 of mattermost) without it just breaking?

Judging from this ( [Solved] GitLab 8.9: panic: runtime error: invalid memory address or nil pointer dereference ) it will be a little while.
