If you find a bug or would like to suggest a new feature, it is probably easiest to send an email to mattyowl[at]users.sourceforge.net.
Alternatively, please feel free to file a bug report using the Tracker.
In either case, please include details of your operating system, python version, and versions of the python packages required by astLib that you have installed on your machine. For any WCS-related bugs, it would be helpful if you could also include the image header as a text file so that I can reproduce them easily.
Note the latest development version in the git repository can be obtained by doing:
> git clone http://git.code.sf.net/p/astlib/git astlib-git
at the console.
