I recently asked the question about finding downloadable firmware builds and got the reply for what I was looking for here: http://discuss.px4.io/t/are-there-daily-downloadable-firmware-builds-somewhere/8105?u=ocularmagic
When I follow the links suggested, it took me to a totally unfamiliar site which, in my limited experience, was not very easy to understand. On top of that, it was visually totally unrelated to the Dronecode project. Also, I was not able to easily find it through browsing the regular documentation within the Dronecode pages. I'm sure there are any number of reasons that access to these may seem unnecessary, but I think the more easily accessible they are, the easier users will find it to use it in their own way. If there is a way to incorporate downloadable pre-built files like firmware/bootloaders easily within the Dronecode web site, I think it would benefit new users.
