Beginning with version 2.1.0, we are adopting a new versioning scheme for the Phaxio API. While superficially similar to Semantic Versioning, there are crucial differences.
API versions will now have the following format:
Updates in either the
MAJOR segment are considered breaking. The difference between the
two is philosophical, with a core update indicating a fundamental change, and a major update
indicating an improvement. Either way, existing client code is unlikely to work with the new version
Updates in the
MINOR segment indicate non-breaking changes. Changes that are considered
non-breaking include adding an action, adding an optional request parameter, adding a response
parameter, and adding an object attribute.
Client Library Versioning
Client libraries should follow Semantic Versioning. Their version numbers are unrelated to those of the Phaxio API.
