Program from Unknown Source

[Programmer]

For the last few days if you tried to install the program you would have seen a message about it being from an unknown source or not being trusted. This is because my code signing certificate expired on January 25, I now have it reissued for another three years so everything is back to normal. If you still see the message in the next twenty-four hours it is due to caching but it is perfectly safe to override it and choose "download anyway".
