There is only one breaking change to be aware of when upgrading from Asterisk 14 to Asterisk 15:
- Core:
- The 'Data Retrieval API' has been removed. This API was not actively maintained, was not added to new modules (such as res_pjsip), and there exist better alternatives to acquire the same information, such as the ARI. As a result, the 'DataGet' AMI action as well as the 'data get' CLI command have been removed.
