*Gaim* 2.0 Beta 1 -> "Beta 2":http://gaim.sourceforge.net/

* more streamlined UI
* faster sign in (for MSN network, anyway)
* Still no MSN personalized status message. :(

*Firefox* 1.5.0 -> "1.5.0.1":http://www.mozilla.com/firefox/releases/1.5.0.1.html

* didn't noticed anythings
* The download size is only 751 kB. (via automatic update) I didn't know they have incremental upgrade! This is cool.
* Official release note lists improved stability, security enhancements, and memory leaks fix as the highlight. This can only be good.
