Office -> Settings -> "Financial information is required" has been split into budget and real numbers, so you can control whether none, one or both are required when creating and saving a project. If you had financial information required before release, both budget and real numbers are still required (no practical change), but Office admins can change this. If at least one is required, "number of people" in Project Settings is mandatory, for reporting purposes.
Smaller improvements and bug fixes.
