The intention is to move to a less restrictive licence in future, where commercial hardware derivatives are allowed but the use of the Labrador name or any branding is not. If anyone knows how to implement such a licence, I'm all ears.
Known bugs.
Most of the main bugs have now been fixed, including all synchronisation issues. There are still a few small bugs, most notably a crash when you disconnect and reconnect the board on a non-Windows platform, and the issue with the logic analyzer still persists. Both will hopefully be cleaned up before launch.
Collaboration
Mailing list is here and open to all who wish to collaborate on the project: https://groups.google.com/forum/#!forum/labrador-devel
Thanks to all.

Questions
How big is the Tinylab proto1 PCB?
It measures 33.2 × 34.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Tinylab proto1 use?
59 parts, built around the ATXMEGA16A4U-AU, LM324, DMN63D8LDW and 78L05. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Tinylab proto1 KiCad files?
From the EspoTek/Labrador_backup repository on GitHub, at the commit this page was made from: the board is PCB/OUTPUT_V35/Tinylab_proto1.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Tinylab proto1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask EspoTek before reusing the design.
