I would detest a DAW software package that auto updates.
Cake does a good job of publishing when an update is available for SONAR. Maybe less for synths (none if is 3rd party like Addictive Drums, that's XLN's job).
Some users (a scant few) have noticed they don't get an email about updates to SONAR but then they come here to express their concern about something else and THEN!!!!!! they find out there is an update.
THEN you know what they do? They decide when to update.
Pretty nifty if you ask me.
