I've just "upgraded" to Blosxom 1.0, and it was (of course) a smooth process.
Congrats, Rael, on hitting the mythical 1.0!
I finally figured out where to modify blosxom.cgi so that it doesn't render the entire freaking blog with each static rendering of the site... Easy change in line 167, to remove the first condition (if dynamic, pay attention to the entry count limit) - after removing that condition, all pages will obey the entry count limit.
Update: Well, that didn't work so well... Fixed the post-every-entry-to-the-.html-flavour problem, but munged the xml feed. Doh.
