Upgraded to Roller 2.0, Tomcat 5.5.12 and using Acegi Security
After a failed upgrade yesterday, I was able to successfully upgrade to Roller 2.0 today. The Editor UI is definitely nicer, and you can get a taste of it if you like by logging into my test user account. The username is "test" and password is "roller". You can also check out my planet page.
In addition to upgrading Roller, I upgraded Tomcat from 5.0.28 to 5.5.12 and everything seems to be humming along smoothly. I'm also running the Acegi integration patch for Roller instead of container-managed authentication. Hopefully this will help us identify any issues. I really like the Acegi integration so far, especially b/c the Remember Me stuff is checked at the root-level and I never have to click "Login" anymore. Good stuff.
Let me know if you see any issues.
