Normally you're on the ball #6, but in this case not so much. One of the reasons kas1e decided to stop OS4 development was because Hyperion doesn't post that kind of information, and ssolie even confirmed that they do not plan to. I expect what will be in the official support blog is a vague " bug fixes and/or improvements" with no specific or useful technical information.
Also, yes, it's A-eon on the hardware side, but it's up to Hyperion to make OS4 take full advantage of the hardware on the X1000, which it currently does not (to put it mildly). Thankfully Varisys ported Linux so the boards aren't completely useless.
Nevertheless, I see where ssolie could answer Piru's questions, which are questions a potential customer might ask. I also see those as quite different than what Roman's issues are, which would apply to specific changes that only a developer could relate to for his own benefit.
