Changelog
Material changes to the API: new endpoints, parameters, response fields, deprecations, and breaking-change notices. Cosmetic dashboard updates and internal performance work are not logged here.
Versioning policy
The current API version is v1. We commit to keeping the v1 contract backward-compatible for the foreseeable future:
- Additive changes (new endpoints, new optional parameters, new response fields) ship without notice. Your code should ignore unknown fields and tolerate new endpoints appearing.
- Behavior changes that could affect output (e.g. tighter validation, calculation refinements) ship with at least 14 days' email notice and a tag here.
- Deprecations (a field or endpoint planned for removal) ship with at least 90 days' email notice and a tag here. The deprecated thing keeps working through the deprecation window.
- Breaking changes (removed fields, renamed endpoints, schema redesigns) only happen on a new major version (
/api/v2/). The previous major stays online for at least 180 days after the new one launches.
