This release is a maintenance update to fix some bugs, make some tweaks, and also update all the documentation in preparation for a stable release. If all goes to plan, the next update will be a stable one, then we'll begin the next cycle of adding new features through beta releases again.
Please make sure you report any issues you've noticed to the Bugs forum. Issues reported before the stable release can be included in the stable update, but if you report afterwards you may have to wait a couple of months for it to reach the next stable update after that. There have been lots of new features lately so please stay vigilant and make any reports about issues you think should be investigated!
Edit: we're also introducing an experimental new torrent download option. If the download is going slow for you, try clicking 'Alternative torrent download' beneath the download button.
