I just downloaded and installed the newest version of Calibre today. I was getting book covers and metadata including descriptions before the update. If no comments or description was available I would paste them in.
After installing the update the comments section is now grayed out and I can't paste anything into the comments section. I also tried to paste into the comments when converting from .lit which looked like it would take but after conversion no comments when displaying the book.
I appreciate the program and this is just a FYI heads up.
