How so? It is actually one of the very first things mentioned: > This is a major new release, with new or improved features, including namespaces. The relevant part of the NEWS file is appended below. So you would be happier to have the item as number 1 rather than 11 in the list further down? > 11. Namespaces have been implemented! See the manual. One consequence of this is that files included with -i, read with -f, and command line programsegments must all be self-contained syntactic units. E.g., you can no longer do something like this: gawk -e 'BEGIN {' -e 'print "hello" }' I found the announcement rather concise and to the point. Apart from that it would have been nice with a reference to what section of the manual to look at. Especially as https://www.gnu.org/software/gawk/manual/ https://www.gnu.org/software/gawk/manual/ still references 4.2 (will probably be updated soon).
