hot-babe/hot-babe.c
Eirik Øverby 6aff485ced Release 0.2.2 - last known release 
Website disappeared between Jun 15, 2010 and July 7, 2012.
No intermediate releases have been found, but it might be possible to reconstruct from Debian source diffs - I have made no attempt to do so.

0.2.2:
    Added option --version, -v
    Added hot-babe pixmap
    Bugfix when the number of pictures was not 5, resulting on awful colors
    Inform the wm that hot-babe is a dock (I really didn't check it)
    Added option --geometry to position the hot-babe

0.2.1:
    - Fixed some include missing for FreeBSD
    - Added support of a user configuration and pictures directory
    - Added configuration example file
    - Fixed segfault when the number of pictures was smaller than 5
    - Update man page
    - Fixed Makefile to follow right DESTDIR/PREFIX usage ;-)

0.2.0:
    - Using gdk2 and gdk-pixbuf2
    - License is now "Artistic License" for code and pictures
