The online documentation for 2.3 is now available (the CHM will be made available when 2.3 is released).
It's taken a bit longer than I would've normally liked but there have been a few fairly significant new features in this release cycle that needed a lot of documentation (e.g. the new template processing engine).
I've tightened up a lot of the writing  and it definitely looks much better than before. It's been almost a year-and-a-half since the 2.2 release so I figure it's worth taking an extra week or two to make the documentation look good Just my Japanese heritage showing through again, I s'pose
Feedback is, as always, most welcome.
 Gawd, I waffled on dreadfully in the 2.2 help. Why didn't anybody say something?!
