Adium has been updated to v0.86. “AIM users with large buddy lists will be glad to see that the recent problem with rate limiting errors while signing on has been resolved (changes to the AIM servers caused this problem, which affected most third party clients). Among other fixes and enhancements, we’ve also improved the File Transfer Progress Window and corrected an issue with .Mac accounts which was introduced in v0.85.” The release notes are available here.
