  • If you have the Authorize Project plugin installed and configured, its configuration will now be treated as final with respect to the behavior of Job/Build checks from Build other projects and Build after other projects are built. Formerly, if a Per-project configurable Build Authorization was enabled globally but some projects did not specify an Authorization, the two aforementioned checks would automatically fall back to checking as anonymous (typically denying build permission). To restore the former behavior, explicitly configure a Project default Build Authorization to be Run as anonymous.
