I guess there are a couple of Genshi users here so this might be useful
to some of you: Genshi development basically came to a halt some months
ago. As the lead developer (Christopher Lenz) moved on to other
projects, de facto no-one is maintaining the whole thing.
There is at least one regression which proved really hard to debug (1).
After the upcoming Genshi 0.6 release, Genshi will be basically
unmaintained (2). trac will switch to Jinja2 as default templating
language in 0.13.
So if you're using Genshi, this might be the time when you need to step
up and contribute to this open source project.
