Well, I do think ROL has a feature list on their website for each update. However most of the ROL website is a huge mess and needs updating instantly for example the bulk load of info still dates to 1999 of the original RO4 update. " RISC OS 4 is 99.9% Millennium compliant when run on any existing ARM based Acorn machines." Hooray that was ten years ago! It also states that they will make the software 32 bit in 12 months.
