I've released Twine 2.0.9pre1! As the name implies, this is a prerelease version intended to shake out last-minute bugs before I do a full release; as such, it isn't linked from the home page. I've written a blog post
explaining how to download it as well as what's new.
As I wrote there, feel free to post general feedback here! I would like to handle straight bug reports over on Bitbucket
so that it is easier for me to keep track of what has been addressed and what still needs to.
