New release candidate

I’ve just published a v5.1.1 at https://drive.google.com/drive/folders/0B8UeIGgvyx2VQXRDVndvTUVlUFE?usp=sharing. It will act as a release candidate. Please use it, test it and let us know if you run into trouble.

When nothing new is reported I’ll publish this version by the end of the week as the new stable version.

I’ve promoted the release candidate as the new official new version (v5.1.1).
