Sam Lantinga wrote in to the Simple DirectMedia Layer mailing list to announce that the media library used in countless Linux game projects over the past decade and beyond will now be under the zlib license:
Galaxy Gameworks will no longer be selling licenses to SDL, but will
continue to support our existing customers.
SDL development will continue, but will largely be community driven and Ryan and I will continue to coordinate patch integration and SDL releases. We will be working to make it easier to contribute in a variety of ways, and are looking for people interested in helping out.
