Hi all,
Pd version 0.56-1 is available from https://msp.ucsd.edu/software.htm or (source only) via github: https://github.com/pure-data/pure-data
This fixes a problem in 0.56-0 which could prevent Pd from starting up on macintoshes on which the menus were not in the English language, along with several other problems for all platforms.
I've since heard about a couple of remaining problems with mousing on scalars ('structs') which probably won't affect many people but which will need fixing.
cheers Miller
