If you're interested in grep development and announcements, please subscribe to the new list, grep-de...@gnu.org, via this link: https://lists.gnu.org/mailman/listinfo/grep-devel.
Why? The bug-grep list is for bug reports: every new thread there gets its own auto-created "issue" that must then be triaged and eventually closed. It does not make sense to require that for many announcement or discussion-style (non-bug) threads. I will probably post about the next release to the bug list, but not after that. In case I have your attention, still, please chime in if you have any non-invasive/safe pending patches, because I want to make a new release soon, in large part for this bug fix: ** Bug fixes Grep no longer omits output merely because it follows an output line suppressed due to encoding errors. [bug introduced in grep-2.21]
