Please enjoy this release of ack. It's been a long time coming, and I apologize for that. ack is getting a resurgence of my time and there are some good new changes coming down the road.
Thanks for your use of ack. If you use something besides ack, that's great, too. There have been an explosion of other greplike tools that have come out recently. Visit the list at
https://beyondgrep.com/more-tools/ to see what else is out there. Use whatever best suits your needs.

====================================
[CONFUSING BEHAVIOR & UPCOMING CHANGES]
The -w has a confusing behavior that it's had since back to ack 1.x
that will be changing in the future. It's not changing in this
version, but this is a heads-up that it's coming.
ack -w is "match a whole word", and ack does this by putting turning
your PATTERN into \bPATTERN\b. So "ack -w foo" effectively becomes
"ack \bfoo\b". Handy.
The problem is that ack doesn't put a \b before PATTERN if it begins
with a non-word character, and won't put a \b after PATTERN if it
ends with a non-word character.
The problem is that if you're searching for "fool" or "foot", but
only as a word, and you do "ack -w foo[lt]" or "ack -w (fool|foot)",
you'll get matches for "football and foolish" which certainly should
not match if you're using -w.
