Although some the OS's components were already available under permissive open-source licenses such as the BSD and CDDL licenses, ever since RISC OS Open's inception the primary license has been the Castle License, which came in commercial and non-commercial flavours, neither of which satisfied all of the requirements that the OSI deem necessary in order for the code released under that license to be considered "true" open source. So although the "shared source" Castle License was better than nothing and certainly played a big part in RISC OS's survival post-Iyonix, many people have also felt that it's been holding the platform back. ROOL and ROD hope that by relicensing the OS under this new license, developer and user interest in the OS will increase, and the OS will be kept free to grow and evolve into the next decade and beyond.
More information about what this means for RISC OS and what ROD's and ROOL's plans for the future of RISC OS are will be released at the London Show this weekend.
