 # GAP - history of changes
 
+## GAP 4.12.2 (December 2022)
+
+The following gives an overview of the changes compared to the previous
+release.
+
+- [#5250](https://github.com/gap-system/gap/pull/5250) Fix an unexpected error during tab completion for input like `a.b.` when `a` is not a record
+- [#5235](https://github.com/gap-system/gap/pull/5235) Fix a problem with kernel extensions on macOS
+- [#5187](https://github.com/gap-system/gap/pull/5187) Allow kernel extensions to use GAP header files via `#include <gap/HEADER.h>` instead of `#include "src/HEADER.h"` or `#include "HEADER.h"` (improves compatibility with "install" GAP versions shipped by Linux distributions)
