|Is MySQL slowly becoming a closed source company from open source ? Not really.
But, according to the new changes to the release policy in the availability of both MySQL community and enterprise editions, MySQL will no longer make the source tar balls available to regular community releases, instead available to enterprise paying customers and there will be four yearly source tar balls available for community releases. Enterprise release will have monthly updates along with quarterly service packs. Bugs will be fixed in enterprise release but only to the current development tree of community tree.
With this change, looks like MySQL can attract most people to buy enterprise license; by slowly moving or loosing the big open source community. But this will cause more work for me at Yahoo!
