On Tuesday 19.3. we will upgrade the XWiki version on our wiki, from 15.7 to 15.10.7.
Because of this upgrade, there will be a service break for wiki.helsinki.fi. We have reserved one hour - from 7 am to 8 am, but if everything goes ok, the service break will be shorter.
15.10.x is the Long Term Support (LTS) version and we will stick with it until next major LTS version 16.10.x comes out (in the autumn 2024).
From now on, we will try to upgrade to the next LTS minor version as soon as possible (15.10.8, 15.10.9, ... etc).
