0.20.11 and testing continues

I've just released the latest version. It includes more fixes and a few nice minor updates. Thanks to everyone that's been emailing me bug reports.

I'm hoping to release the first official version at the end of February. I think the big bugs have been fixed, and hopefully all that remains are minor tweaks.

There are now 41531 lines of code, and it's all free to anyone who wants to use it.

If you do find it useful then please consider donating to a local cat charity or shelter.

Thanks.
