I'm one of the folks who was on Cutline for ages, and has been startled by the forced (and unannounced, to me at least) change to Coraline.
The current issue: I used the 'font size=small' code (in chevron brackets, of course) a lot in my blog, mainly as an easy way to distinguish little notes under images from the main text of each post. Now it's not working. Like Coraline doesn't recognize that particular code anymore, while Cutline handled it just fine.
I found that if I use 'span style="font-size:xx-small;' I can get the small text again, which is fine for new posts, but I really REALLY do not want to have to go back through years of near-daily posts to restore all the formerly small font to the way it was supposed to look. Please tell me there's something I can do to fix this (or, better yet, something WordPress can do to fix it)...
