With the update to this version the names of certain system born users are changed so they don't contain spaces. When changing a username the user is automatically logged out which means the update procedure will end in a login screen. This has no negative consequence as the update is successful but we still recommend using a different user for the actual update to avoid any trouble. So reuse another login or create a temporary one. The user does not need to be a member of any groups or roles so any login will do.
The following user names are changed:
Super Administrator → SuperAdministrator
Content Creator → ContentCreator
Light User → LightUser
Collection Template → CollectionTemplate
DAM Guest → DAMGuest
Avoiding deadlocks
As part of the ongoing work to improve the underlying datalayer a digimonitor event has been deemed obsolete and removed. The event was "MediaTranscodeProxyDestination Updated". When in need of a workflow that should trigger when media transcodes are done use "Asset ProfilePublished".
