As promised, Blackmagic announced today that DaVinci Resolve 9 is available to the public, albeit as a beta, but still available. For existing Resolve users this is (or will be when it's a final, gold master release) a free upgrade.
*****Remember "beta" means that the public is welcome to download and use it, but it is not a final version. There are and may be bugs that hinder your particular workflow. Download and install with extreme caution.****
