Hi all, I've put up the Yesod 0.8 migration guide[1]. I'm planning on releasing this version of Yesod tomorrow night (Saturday, UTC+3). Now's your chance to try and find those last few bugs before release. I have one idea that I wanted to bounce around. The biggest thing in this release is the transition to Text. Overall, this is a good move, but it's just a little bit annoying to lose out on convenience functions like concat and ++. As a convenience, I'm considering exporting the following from the Yesod module: mconcat (from Data.Monoid) <> = mappend (from Data.Monoid) Text (the strict version, from Data.Text) I know there was some talk a while ago of providing a <> operator in base, but I haven't heard anything about it since. I think this could be a very nice convenience, and would appreciate feedback. Michael [1] http://www.yesodweb.com/book/migrate7to8
