A reason for major ports update?

[Steve Lake]

	Ok, call me the curious cat, but I just cvsupped my ports tonight looking 
for a patch to Xine to fix a problem with MKV playback under KDE 3.5 and 
got quite the shocker.  There were about 101 ports that said they needed to 
be upgraded.  The part that's the kicker is I just upgraded everything 
about 3 weeks ago.  Did I miss something or did something big come down the 
pipe that caused a major number of ports to be updated?  Or is this just 
coincidence?  Just curious.
