Full changelog here

Due to encoding differences, importing from sites that are not plaintext will cause issues for any special characters. Use a site that supports a plaintext view.
Bukkit pastes do support this, just add .txt at the end of the url, e.g. http://dev.bukkit.org/paste/gy7ekjupawivnbxq.txt.
A basic rule of thumb: If right clicking -> view page source doesn't look pretty much like your book, it might not work right.
