Provide release notes

[Soleone]

Now that Scatter is updated automatically there is no clear place where users can see what changed in the latest versions.

It would be great if there would be a link available for every release that could be sent to users at least manually (bonus points if it can show up inside Scatter, but that's for later).

This way users can confirm if a potential problem they previously had is now fixed, or just have a way to show off the continued development of Scatter.

For example here a list of the very important changes would be nice: https://github.com/GetScatter/Bridge/releases/tag/v1.0.12
