Yeah, it’s the day after a release and I’m releasing another one. Got some good reports yesterday of some formatting troubles with certain things in the ePub export, and I just couldn’t stand to let them sit there and fester. All of them are fairly minor, unless you’re trying to have the copyright symbol display correctly, or you use accented characters.
Read the release notes. There’s information about how to add clickable URL’s and email address to your ebook.
