This release is an attempt to mitigate false positive anti virus issues with AVG and Avast.
In previous versions only the installation package was digitally signed.

All the executables are now also digitally signed with an EV (Extended Validation) certificate.
Also changed is the configuration of the built in web browser as that may have caused a false positive.
