We have a new beta of the Flash Player 6 today, with versions available for Windows, Mac, and Linux.
This is a very big release, with quite a few bug fixes, new features (wider WMODE support, custom request headers, etc…) and performance optimizations.
We are really trying to create as high a quality player as possible, and thus we need your helping in reporting any issues / problems that you run into (we are giving prizes away to the top bug submitters).
Here are the links:
Remember though, that this is a Beta and should not be used in product environments.
Post your favorite feature, bug fix in the comments. I will also be hanging around in the chat answering any questions that come up.
