As reported first on The IconBar and then in more depth on Drobe, RISC OS Open Ltd have announced that, along with Castle, they will be releasing various parts of the operating system under a “Shared Source” licence. Apparently this will allow people to contribute changes to the source code and distribute their resulting programs for free; if the code is used commercially though, the writers much pay a small royalty for the privilege (although in this case, they are no longer obliged to contribute back the code they have added).

I think this is potentially a very good thing for RISC OS, I just hope it hasn’t arrived too late in the day.
