Indeed but Im old school set and forget type of guy. I had issues previously with incompatible packages etc which is why I rarely upgraded QTS and the packages. If it aint broke dont touch it.
I hear you, but QPKGs need continual updates to keep pace with the packaged application requirements.
If it ain’t broke, it soon will-be. 
I updated Sabnzbd to 5.01 with Sherpa not to long ago, but now I get a prompt in the Sabnzbd web interface that there is a new version 5.03 available. Isn’t Sabnzbd updated automatically with sherpa? I’ve restarted the NAS several times.
Hi mate, and welcome to the forum. 
QPKGs will now (by-default) not update themselves on QPKG start/restart. This should yield more stable applications, and quicker application startup times.
You can re-enable this for the SABnzbd QPKG through sherpa with:
sherpa enable-auto-update sab restart sab
