Hello Gang,
For your perusing this weekend we’ve got a few announcements along with the
always informative mailing list recap. New bits to download while you enjoy
fall weather (not if you live in Texas though…)
As always, let us know your thoughts: If you’re working on or speaking
about something Riak related and would like a mention, let me know. I’ll
get your talk, project or blog post in the next Riak Recap. I know a guy.
## Announcements
