ICQ “client version too old” error
Many of you are reporting an error message that started appearing today:
The client version you are using is too old.
Please upgrade at http://pidgin.im/
As for the rest of the error: It appears that, starting today, AOL’s servers now require ICQ 6 or later. Libpurple, in every recent version of Adium, promises to behave like ICQ 5. So, now, AOL’s server responds with “ICQ 5, you say? You’re too old!” Libpurple receives this and passes it on to Adium, which displays it to you.
Once the Pidgin team (they maintain libpurple, remember) fixes this problem, we’ll bring the fix into Adium, and we’ll get it out to you in a new release as soon as we can.
Thanks for your patience.
