We have improved the management of credit when customers are connecting and disconnecting from the SSG. This will mean that the customer is less likely to have messages rejected when they have a low balance.

Changes to the SMPP SMS Gateway platform will be noted in this Changelog section.

Additional API calls added for querying account balance and message status. Implemented callback to webhook for passing DLRs when messages complete. Ability to set message validity period and schedule message delivery.
