I noticed that on https://confluence.atlassian.com/display/HC/HipChat+Server+Release+Notes there is mention of version 1.2.6, especially the directory integration part.
My server is right now on 1.2.5, and my directory integration fails and I have to manually do a sync with crowd.
I tried to do an upgrade but it says none are available in the production channel. Is 1.2.6 released in the production channel? The web page makes it look like it is.
