Atlas Release Cycle

In 2023 we have redefined our 'Release States', and would like to clearly indicate to our clients how this links to our Release Cycle. 

Check in this article for  the definition of the Release State or each version and what that means in terms of impact on support.

Attention: the dates in this overview that are in the future are planned dates only and might change depending on the effective delivery date of a release
