Doing this on behalf of Miller who complained he wasn't getting emails through last week.
Pd version 0.53-2 is available on http://msp.ucsd.edu/software.htm or (source only) via github: https://github.com/pure-data/pure-data/releases/tag/0.53-2
This is for mac people who use the latest OS as it fixes a bug where Pd would hang.
Cheers
