I didn't get a chance to announce version 3.1.0b4  over the "holiday 
break." Basically the changes include fixes for memory leaks in htnotify 
and htsearch (that "20x performance decrease") and a BIG SECURITY HOLE in 
htnotify.


Let me make this very clear: if you use htnotify, either upgrade to
3.1.0b4 
or don't use htnotify. Period.


The hole allows malicious users to execute commands running as the same 
user as that running htnotify. This occurs when htnotify runs in to a 
webpage with a malicious tag. It does not occur when using htdig, 
htmerge, htfuzzy, or htsearch.

I do not know of any cases where this hole has been used. It is present in 
all of the 3.1.0bX versions up to 3.1.0b4. It may be present, though to a 
lesser degree, in previous versions.
