Hey plugin authors, would it be an idea to keep a wiki page so we can document api changes that impact our plugins? I dont know about you, but I run into issues sometimes, and it takes me hours to figure out some RC core change has made my plugin unpredictable. Recently this was the case with buttons in the compose template suddenly requiring registration in some array. Another one that probably impacted most of us a while back was the sudden change in the display_message call, requiring the lock argument.
I can understand that RC isn't a stable platform yet for plugins, especially since we basically use core functions instead of a real API, but it would help if we dont all have to re-invent the wheel every time something changes.
