Miller Puckette to the Pd list
"Pd 0.55 Test 3 is out. This should resolve all the trouble we've had with test2 except that one tester on MacOS is still finding that Pd 0.55 loads way more slowly than 0.54 - I don't see that happening on my machine and I don't know how many machines will be affected... it might take a while to track this one down, but hopefully it won't affect many people. If you do notice longer startup times on MacOS please let me (or the Pd list) know - with more data points it migth be easier for me to replicate the problem for myself.
