- Changelog
    5.3.2
	1. The pretty printer now produces fewer spurious newlines; at the
	   outermost level it now adds newlines between block comments and
	   the block or function that follows them. The extra final newline
	   is no longer produced.
	2. OpenVMS 9.2-2 x86_64 is now supported.
	3. On Linux and macos systems, the -no-pie linker flag is no longer required.
	   PMA now works on macos systems with Apple silicon, and not just
	   Intel systems.
	4. Still more subtle issues related to uninitialized array elements have
	   been fixed.
	5. Associative arrays should now not grow quite as fast as they used to.
	6. The code and documentation are now consistent with each other with
	   respect to path searching and adding .awk to the filename. Both
	   are always done, even with --posix and --traditional.
	7. As usual, there have been several minor code cleanups and bug fixes.
	   See the ChangeLog for details.
