    ## Versioning and deprecation


    The API has a single stable version served at https://api.postproxy.dev/api. Releases are identified by this document''s date-based `info.version`. Changes are additive: new endpoints, new optional parameters, and new response fields may appear, and clients should ignore fields they do not recognize. Existing fields, parameters, and status codes are not changed or removed without a deprecation cycle.


    When an endpoint or field is deprecated it is marked `deprecated: true` in this specification and announced in the changelog (https://postproxy.dev/getting-started/changelog/) at least 90 days before removal.'
