I will briefly enumerate the changes at Codeforces:
- Codeforces beta Round #1 is announced. It will go according to the ACM-ICPC rules, but will last for 2 hours. You shouldn't expect much from the problems - in the first place it is organized to check the system function and your feedback. The problems will be in two language: Russian and English. If I finish all the preparatory work earlier, I'll bring the Round some two days forward. It's planned to have the rating system at Codeforces similar to that at TopCoder. If the beta-competition goes without system failures, the participants will get ratings. To take part you are to register first.
- The visual organization of “Recent actions” has been changed - "new comment" and "compose/edit text" can be seen in the sidebar. Blog entries are sorted by the date of events, it means the last 15 entries are displayed.
- A new “Recent actions” detailed page, from which you can clearly see who has been doing what in recent time, is introduced.
- The algorithm of your "contribution" evaluation has been changed. For more details see below. I think I might change something again later.
- I've fixed some bugs.
