This beta has taken a little longer than usual to release since we were out of the office for the winter holidays. Thank you for your patience!
New this build: a new open in external editor option in the image editor. The path to the external editor can be set in Preferences under the 'Misc' tab. You can set this to another image editing tool like Photoshop, Paint.NET or something else. Then you can use the new image editor button to launch this editor to edit the current image instead. This should hopefully alleviate the fact the image editor only has some fairly basic editing features, and is unlikely to reach the same level as tools like Photoshop anyway.
There's also a fairly big batch of bug fixes in this release, so hopefully it will clear up a number of issues. As ever please test carefully and hopefully if everything is working smoothly we can have another stable build out soon.
