The relevant part of the NEWS file is appended below. This release represents a lot of very hard work by a number of people. I thank them all for their contributions, I could not have done it by myself. Differences from gawk 4.2.1 are not available; they would be too large. The usual GNU build incantation should be used: tar -xpvzf gawk-5.0.0.tar.gz cd gawk-5.0.0 ./configure && make && make check Bug reports should be sent to bug-g...@gnu.org. Enjoy!

Changes from 4.2.1 to 5.0.0 --------------------------- 1. Support for the POSIX standard %a and %A printf formats has been added. 2. The test infrastructure has been greatly improved, simplifying the contents of test/Makefile.am and making it possible to generate pc/Makefile.tst from test/Makefile.in. 3. The regex routines have been replaced with those from GNULIB, allowing me to stop carrying forward decades of changes against the original ones from GLIBC. 4. Infrastructure upgrades: Bison 3.3, Automake 1.16.1, Gettext 0.19.8.1, makeinfo 6.5. 5. The undocumented configure option and code that enabled the use of non-English "letters" in identifiers is now gone. 6. The `--with-whiny-user-strftime' configuration option is now gone. 7. The code now makes some stronger assumptions about a C99 environment. 8. PROCINFO["platform"] yields a string indicating the platform for which gawk was compiled. 9. Writing to elements of SYMTAB that are not variable names now causes a fatal error. THIS CHANGES BEHAVIOR. 10. Comment handling in the pretty-printer has been reworked almost completely from scratch. As a result, comments in many corner cases that were previously lost are now included in the formatted output. 11. Namespaces have been implemented! See the manual. One consequence of this is that files included with -i, read with -f, and command line program segments must all be self-contained syntactic units. E.g., you can no longer do something like this: gawk -e 'BEGIN {' -e 'print "hello" }' 12. Gawk now uses the locale settings for ignoring case in single byte locales, instead of hardwiring in Latin-1. 13. A number of bugs, some of them quite significant, have been fixed. See the ChangeLog for details. -- If you have a working or partly working program that you'd like to offer to the GNU project as a GNU package, see https://www.gnu.org/help/evaluation.html.
