To this point, if you're releasing minor-version changelogs, expect them to be posted on sites like HN, and make sure you link at the top of the post to the announcement of the latest major release, for those who might have missed it! It's an easy marketing win!
Minor releases (and plenty of not minor ones) are moderated away as mostly offtopic on HN since they turn into generic discussion of the project itself which is more often than not, a dupe. The saner thing is to just not post them/flag them.
I imagine that will pick up somewhat in about 20 minutes, or rather new articles will start to hit over then next 2 hours (Apple event starts at 1pm ET)
It sparks a discussion around knowledge management, that's kinda nice :)
Personally I appreciate the fix for "Reveal in Finder" hanging a system app (Finder). I also wanted to see how people think of the Properties feature, which has not been discussed yet on HN.
