Adobe has released Flash Player 11 beta, the new version being available for both 32bit and 64bit (yes, for Linux too!).
A lot of people are experiencing red/pink tint on YouTube videos starting yesterday. The cause seems to be a combination of Flash 10.2, a recent YouTube change and the users graphics cards and seems to be browser-independent (can occur in Firefox 3.x, Firefox 4 beta as well as Chrome / Chromium). Here are some solutions which will hopefully fix the red YouTube videos bug.
Adobe Flash Player 10.2 beta was released today with preliminary support for Stage Video which is supposed to reduce the performance impact while playing back video content across all platforms.
The Sevenmachines Adobe Flash Player 64bit PPA for Ubuntu has just been updated with the latest Adobe Flash Player "Square" 10.2.161.22 (64bit obviously) for Ubuntu 9.10, 10.04 and 10.10 so now it's even easier to install it!
If a while back Adobe wasn't very interested in its 64bit Linux users and discontinued Adobe Flash Player 10.1 for 64bit, the new Adobe Flash Player codename "Square" developer preview released by Adobe today is also available for 64bit Linux systems (and obviously, 32bit too).
