Upgrade Codeunits in NAV 2015
Once upon a time, and really not such a long time ago, there was no such thing as a codenit type. In all honesty, there is still no such thing as a codeunit type – there is subtype, though. (Why we have subtypes, without having types, beats me, but let’s let the semantics go.)
Nowadays, we have four codeunit types. NAV 2009 SP1 brought along the Test and Test Runner types, which – in my experience, at least – haven’t seen much runtime (which is a pity, if you ask me). And now NAV 2015 brings along another type: the Upgrade codeunit type. The mere sound of it makes my heart thrill. The Upgrade codeunit. Mmm.
