+Changes from 5.2.1 to 5.2.2
+---------------------------
+
+1. Gawk no longer builds an x86_64 executable on M1 macOS systems.
+   This means that PMA is unavailable on those systems.
+
+2. Gawk will now diagnose if a heap file was created with a different
+   setting of -M/--bignum than in the current invocation and exit with
+   a fatal message if so.
+
+3. Gawk no longer "leaks" its free list of NODEs in the heap file, resulting
+   in much more efficient usage of persistent storage.
