I have posted Centos rpms for the latest version (0.19.1) of the Geany programmer's editor here:
http://www.melvilletheatre.com/articles/el5/index.html
i386, x86-64 and src.rpm are available.
0.19.1 is a bugfix release, details here: http://www.geany.org/Documentation/ReleaseNotes
The last time I posted a geany announcement on this mailing list, there was a substantial spike in the number of people who downloaded it so apparently there are a lot of people here who use geany.
If you're a programmer and haven't tried geany yet, do yourself a favour and try it out. It's my favourite programmers editor.
