KDE SC 4.5 is about to be released and KDE SC 4.6 is being discussed. However, Martin Graesslin has revealed some details about what they are planning for KDE 4.7.
According to Martin's blog post, they are looking at OpenGL 3.0 to provide the compositing effects in KDE SC 4.7. OpenGL 3.0 provides support for frame buffer objects, hardware instancing, vertex array objects, and sRGB framebuffers.

"OpenGl 3.0 is the biggest change. Going from 2.x to 3.0 is a lot harder than going from 3.0 to 4.1"
yes but going from 2.x to 3.3 (an incremental release on the 3 series) would make sense to bring it to that level of fixes in the 3 series since the first 3.0 release was deemed "incomplete" by most OpenGL coders who work on games (and CAD and other stuff), myself included.
Going from 2 to 4 would have a huge leap, but going from 2 to 3.3 wouldn't be terribly more difficult as the architecture is fundamentally the same as the previous few 3 series releases.

That's true, but it's not going to happen all it once. Each extension has to be implemented separately, and it makes a lot more sense to do the 3.0 extensions before the 3.3/4.1 extensions. However, once Mesa gets full OpenGL 3.0 support, I don't think 3.3 will be far off (contrary to the people who say that it will take another five years).

So, the Xbox One disaster continues. Microsoft's policy for dealing with the used games market has reportedly leaked - and it's a clear and direct attack to destroy the used games market. Prices for used games will be set at the retail value of a new game, and retailers have to hook into Microsoft's computer systems and comply with Microsoft's terms and conditions.

At an event earlier today, Microsoft unveiled the next Xbox - the third model, but confusingly named Xbox One. The big focus was TV, integrated Kinect, and all the other stuff we all expected to be forced down our throats. I think it took them 25 minutes to actually come to what should be the core of the story: gaming. Nothing groundbreaking in the gaming department, except for how Microsoft intends to handle the used games market and borrowing games from friends: pay up, buddy!

The day has finally come! Jolla has finally announced the launch device for its Sailfish operating system - and by god this is a looker. It's decidedly different from other phones out there, but it has good specifications and carries a relatively reasonably price tag - EUR 399, and it's up for pre-order today, shipping in the fourth quarter of this year.

Why does Google get so much credit in the technology industry? Why, despite the company's many obvious failings, do many geeks and enthusiasts still hold a somewhat positive view on the all-knowing technology giant? A specific talk at Google I/O this week provides the answer.

"Windows is indeed slower than other operating systems in many scenarios, and the gap is worsening." That's one way to start an insider explanation of why Windows' performance isn't up to snuff. Written by someone who actually contributes code to the Windows NT kernel, the comment on Hacker News, later deleted but reposted with permission on Marc Bevand's blog, paints a very dreary picture of the state of Windows development. The root issue? Think of how Linux is developed, and you'll know the answer.

This is one of those news items that's fun to write, fun to read, fun to comment on, and where no one will be able to say anything unkind. It's all just one big ball of awesome fluffiness. TuneTracker, the BeOS radio automation software, has just released something very special: TuneTracker System 5, the first version designed entirely and specifically for Haiku. In fact, it actually includes Haiku in the software package. Better yet, TuneTracker also unveiled several system-in-a-box products - which have Haiku and TuneTracker pre-installed.

Exactly twenty years ago, a document was published that played a huge role in establishing the web as we know it today. Twenty years later, and this simple and straightforward document is proof of an irrefutable fact: while closed technologies can change markets, open technologies can change the world.

Oh multitasking. That staple of computing that got thrown out the window with many modern smartphones. We got some rudimentary thing in its place - but even as multitasking on phone and tablets improves, its user-visible side remains cumbersome. Windows 8 has a neat implementation, and now it's time Android follows in it footsteps.

They're here! Whether that excites you or not remains to be seen, but the Galaxy S4, which will most likely become the best selling Android smartphone of the year by a huge margin, has been reviewed by all the major sites, and there's lots of interesting conclusions in there - although I think most of you will get the gist.More Features »

I'm not sure how you think 3.3 or 4.1 would "be a better fit". The best fit is the lowest version that does all the things they want it to do. Requiring newer versions for the sake of "newness" is idiotic.
OpenGl 3.0 is the biggest change. Going from 2.x to 3.0 is a lot harder than going from 3.0 to 4.1. OpenGL 3.0 was the big release that fixed the major architectural problems. All the releases after that were minor incremental improvements (just new extensions).
As I said in my previous comment, if KDE is smart (which I'm sure they are), they will only require the specific extensions that they use, not a certain OpenGL version. This means that, for example, an OpenGL 2.x driver that provides nearly all of the OpenGL 3.0 extensions except for one unimportant one (and thus it can't be called OpenGL 3.0) that KDE doesn't use, would still be able to run KDE SC. Mesa is already nearly to this point. Most of OpenGL 3.0 is implemented, it's just missing a few parts.
