Is it just me? I haven't heard noises about this yet. But I couldn't open lots of my patches in the newest PD last night. Some small ones were OK, but any larger ones (with Graph-On-Parent? Colors?) crashed PD instantly with a Core Dump.
Anyway, I rolled back to PD 52 and all was well. Didn't do more research into the cause; rolling back quelled my curiosity. Just mentioning this for future generations.
