Have you ever wondered about the versioning numbering in the Dynamics 365 Commerce? Here is a small explanation.
If you have a version like 9.49.24030.9, this means
9 – Main release number
.49 – This is the number that increments for each service release. Like 10.0.39, 10.0.40 etc.
.24 – This is the year of the release
030 – This is day number. 030 means 30 January
.1 – Just an incremental counter
So now you can understand the versioning of the CSU/Commerce 🙂
PS! This also means that a quality update on the previous release can be further than a service release, and then the systems will complain about “downgrading not allowed”, even when selecting a newer Service update.
