+       * symbol.c (struct root pointer): Add copy of nextfree[] array.
+       (init_symbol_table): On first alloc, zero out the root_pointers
+       struct. On subsequent uses, copy saved nextfree into real nextfree.
+       (pma_mpfr_check): Check using_persistent_malloc and return early if
+       not using it.
+       (pma_save_free_lists): New function to save nextfree.

+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.
