Greetings all.

This note announces the next release of GNU Awk: version 5.2.2.

This is a bug-fix release. The relevant part of the NEWS file is appended
below. A diff file from the previous release (which should be applied
by running it through /bin/sh) is included.

The online manuals have also been updated.

The usual GNU build incantation should be used:

tar -xpvzf gawk-5.2.2.tar.gz
cd gawk-5.2.2
./configure && make && make check

Please use the buggawk script to report bugs. If it doesn't
work for you, then send email to

NOTE that the manual's instructions for sending bug reports were
updated for the 5.2.0 release. Please review them carefully before
submitting a report!

ONLY bug reports should be submitted to the bug-gawk list. All other
questions should use the relatively new mailing list.

Changes from 5.2.1 to 5.2.2

1. Infrastructure upgrades: makeinfo 7.0.1 must be used to format
the manual. As a result, the manual can also now be formatted
with LaTeX by running it through `makeinfo --latex'.

2. Gawk no longer builds an x86_64 executable on M1 macOS systems.
This means that PMA is unavailable on those systems.

3. 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.

4. Gawk no longer "leaks" its free list of NODEs in the heap file, resulting
in much more efficient usage of persistent storage.

5. PROCINFO["pma"] exists if the PMA allocator is compiled into gawk.
Its value is the PMA version.

6. The time extension is no longer deprecated. The strptime() function
from gawkextlib's timex extension has been added to it.

7. Better information is passed to input parsers for when they want to
decide whether or not to take control of a file. In particular, the
readdir extension is simplified for Windows because of this.

8. The various PNG files are now installed for Info and HTML. The
images files now have gawk_ prefixed names to avoid any conflicts
with other installed PNG file names.

9. As usual, there have been several minor code cleanups and bug fixes.
See the ChangeLog for details.
