I've got a release request up for the Nova Ocata 15.0.1 patch release here [1]. This release contains a few fixes for some high severity regression bugs introduced in the 15.0.0 release. If you have not yet upgraded to Ocata 15.0.0 I'd recommend going with this version when you do to get the fixes within. See the release notes for more details [2] (note these are from the as yet unreleased release notes so they don't say 15.0.1 yet).
