BetterRed, thank you for the link to updated plug-ins. Unlike the Plug-ins Index that appears in the calibre plugins sub-forum, this link tells me which plug-ins are compatible with calibre 2.3.

And davidfor, thank you for your excellent suggestion to contact the developer of the plug-in to request an update either via the plug-in's thread or via a PM. I will do that.

There is just one thing that is still a mystery to me:

As I mentioned, I can't recall the name of my 2nd plug-in because it has disappeared from my Plug-in Updater List. This makes it difficult to find it under "All Plug-ins" or to search for it in these forums. [Edit: See my next post. I was mistaken; there was no 2nd plug-in. One plug-in handled both functions.]

I ran calibre in debug mode both with and without my Sony Reader device connected, and the debug log doesn't show this 2nd plug-in. [Edit: It didn't show it because there was no 2nd plug-in.]

Does anyone know where calibre stores installed plug-ins on the computer's hard drive? (I'm running calibre on Mac OS 10.9.4.) This might lead me to the name of the plug-in if I look for it on my back-up drive (where I have the earlier version of calibre). [Edit: Don't need this info.]
