Blahtex 0.4.1 has been released; now it can get PNGs lining up vertically with the surrounding text (a la PlanetMath, but with a different strategy). No new bug fixes though.

Source, demo, manual, etc available at http://www.blahtex.org/.

Jitse's test wiki (http://wiki.blahtex.org/) doesn't include the vertical alignment functionality for the moment.
