AMD just released the AMD Catalyst 12.6 Beta. With the release of the Catalyst 12.6 Beta driver, AMD would also like to announce that we are moving away from our Monthly Catalyst release plan. Our goal is to ensure that every Catalyst release delivers a substantial benefit to our end users; as we have today with the release of the Catalyst 12.6a Beta. We will still continue with the Catalyst naming convention; Catalyst: Year.Month., You just won't see a new driver every single month. We are confident that this will only benefit the end user; you'll only need to upgrade to a new Catalyst driver, when it makes sense.

We would also like announce the introduction of our new AMD Issue Reporting Form. We made a number of improvements to the older Catalyst Crew Feedback form, making it more comprehensive, ensuring we get the best feedback possible. Feedback is very important in every product company's life, especially in our fast paced environment. This is not just a check-box for us - we take these reports very seriously. We will review every report posted here and investigate every issue encountered. Please use this form whenever you encounter something worth mentioning.

Today Shacknews is reporting that Diablo III will be open to the public for beta testing. The open beta weekend begins this afternoon at 12:01pm Pacific, then will run until 10:00am on Monday, Blizzard explains in a Diablo blog post. All you need to play is a Battle.net account. You can download the client in advance, so you don't miss a second. The beta is relatively small, packing the first part of Diablo III's first act, but you will be playing Diablo III. Unlike proper closed beta testers, open beta players won't receive 'Beta Bucks' to spend in the auction house and cannot post in the beta forums.

Diablo III launches for PC and Mac on May 15. The closed beta test will wrap up on May 1.
