Version 2.6.3 is now available in the master branch of the repository. This release contains bug fixes with a couple updates to third party software versions. Those wishing to upgrade their current receivers to this latest version are welcome to do so at this time as well as anyone wanting to setup v2.6.3 on their own operating system or image. A more detailed description of what all has been fixed will be posted when the release is made official once the Raspbian images have been uploaded. Until then you can look over the v2.6.3 milestone in the issue tracker to see what all has been changed.
I am working on the images now. If things go well and no one stumbles across any game breaking bugs they should be created and uploaded and made available by early morning.
