What did it do?

Ahh, i didn't see that there is a dedicated section for it until now. Can someone move this?

It seems that nobody cares to inform us about these updates. Nothing on the Bethesda blog, nothing on the http://www.creationkit.com/Main_Page, nothing in Steam either...

Basically, the other day the CK was updated to v1.6.91 which caused quite a few problems because it was incompatible with the current version of Skyrim. So they rolled the CK back to v1.6.89 which is compatible with the current version of Skyrim (also v1.6.89).

There was some discussion about this http://www.gamesas.com/topic/1384048-creation-kit-16890-now-live-on-steam/.
