This is done in the same style as #1493, reading release notes.

Also, I marked with (?) the few new features that I’m unsure if they mean any update in this project or not.
I’ll try to go through it in details in the next few days and correct it.

Finally, I’ll try to go through the list to mark what’s already done.
