The issue did affect also the unit LCLIntf in which another OffsetRect had been removed. Juha has fixed this in the meantime as well.
He marked the restored procedurs in LCLIntf and LCLProc as deprecated indicating that they will be removed in the release version after the upcoming one. So, please update your code already now, before you will be caught again: Every unit calling these deprecated procedures must have unit Types in its uses clause.
