KTE 2.1.0 has been posted. I've asked Kovid to update the plugin index entry, which I expect he'll do around the same time the calibre 0.9.42 release is posted.
This update requires calibre 0.9.42 due to some fairly significant changes in the KoboTouch driver. Good changes though, making the necessary changes on my end reduced the size of my code by about 20%
For bugs, 2.1.0 fixes bug 1205702, where met67 has fixed the nested Kobo span tags. Not too shabby for a first run with Python!
