I just got the notification window "A new version is available", which is awesome. My first request is a very small one (UI wise, not coding-effort wise), that when the user presses "Yes" to download the new version that PN automatically downloads the installer exe to the temp folder, then asks to shut down (now or later), and then automatically runs the installer. It could even go a step further by doing a silent install, using the defaults from the previous install, unless the installation options have changed.
Separately (but related), it'd be nice if after an upgrade installation, PN opens a release notes file showing what's changed since the previously-installed version of PN.
Just a couple of small touches. Thanks!
