But check if your local charity doesn't support cryptocoins first, they need it more than I do.

Full change log

Latest version

* 2014-03-24 Windows binary
* 2014-03-24 modified sources files only
NOTE: Chrome will give you a malicious warning on the Windows binary. It is to the best of my knowledge not malicous.
I run Bitdefender antivirus on my build machine to avoid spreading any common malware, but the source is supplied for a reason and you should be able to build it yourself if you wish to.
