I've uploaded 0.12.10-27 (for Diablo and Fremantle). The only change is support for handling svg image tags for EPub book covers (they were already supported within the books, just not for the cover). This support is a bit of a kludge though - the cover processing is done entirely separately from the main book processing, so there doesn't seem to be an easy way to make use of the same code. It works fine for the Baen epubs though, which is where I've noticed the issue.

The source code changes can be downloaded from here.
