No release numbers
------------------
+ - Fri Dec 15 02:04:12 UTC 2000
+ - Parse rate changes *properly*
+ - Add sample code to faimtest demonstrating my approximations
+ on how to fiddle with aim_conn_setlatency() in relation
+ to the rate changes (properly wildly conservative). [I also
+ copied this stuff into mfaim.]
+
- Thu Dec 14 03:39:34 UTC 2000
- Change the 0x01 to a 0x00 in auth request to make buddy lists work again
- Rearrange bytes in setversions() to match winaim
