One caveat about 0.24: you will get a compatibility error if you have the toolbar mod (or any mod that includes it) installed. The fix for this is easy, or at least it was in my case: go download the alpha zip file from the KSPAPIExtensions GitHub and extract the DLL, and overwrite the one that exists in ProceduralFairings. That should do the trick. BIG RED WARNING EDIT SINCE I SEEM TO HAVE ANGERED NK: don't do this unless you're willing to deal with any idiosyncrasies it might introduce. I am a professional software developer who is skilled with debugging and understanding issues with software. I, for one, am willing to accept the inherent risk with swapping out the DLLs. If you cannot say the same thing with 100% certainty, then please just wait for an official update. That is all.
