An Important Note:
Generally the beta is the place where we do design testing, so the game itself is fairly stable. But today we’re releasing a large update specifically for the purpose of stability testing. In particular, we’re testing out our new Replay system, which has been in the works for over a year. As a result, a large amount of code has changed. We wanted to ship it to the beta first, where we can get the bugs ironed out, before we move it out to the main TF2 branch. So please jump in and take a look – we’d love to hear feedback on the UI as well as any bugs you run into.
Also, we'll be wiping all items in the beta at some point in the near future. We will re-grant the achievement items, and any items we're actively tuning afterward.
