While I was writing up the release blog post, I figured out that I've probably been working on Pyblosxom 1.5 on and off for the last three years or so. That's pretty intense---I knew I'd been working on it for a while, but I didn't realize how long it actually was.
The last year or so of development has been fun. There's a pretty consistent contingent of friendly folks who hang out on #pyblosxom. I really appreciate their humoring me with my period, "Pyblosxom 1.5 is almost done! I just have to ..." announcements.
Details of the release are in the release blog post. If you've been waiting to upgrade, this is a good version to upgrade to.
Going forward, I'm going to take a hiatus from Pyblosxom development. I've got a bunch of other projects that I've been ignoring for a while that really need some attention. I'll continue to review patches, help out on #pyblosxom and the mailing lists, and I'll push out future releases, but I won't be doing any major development for a while.
