 ### Deprecated
 
+## [2.42.4] - 2023-12-10
+
+### Changed
+
+- Improved error message for missing labels in GridManager.
+
+### Fixed
+
+- Corrected some unit tests (and test utilities) to fix dangling pointers detected by NAG.  Most (possibly all) of these changes are already on release/MAPL-v3, but it was getting annoying to have NAG fail unit tests with develop branch.
+- Fix for CMake an Apple.  Needs to set `__DARWIN` as an fpp flag.  (Only used by NAG, but ...)
