Main difference in v1.4?

Is there a doc explaining the main difference in v1.4?? I see from the posts that there is a very nice gui coming, but is that it or are there internal engine changes or what?

Many bug fixes, many new features, many CLI commands have changed. You can take a look at the changelog and get some more info.

best/eaiest way to “look at the changelog” ?

Specific URL to go to ?

Doc to dowload ?
