CHANGELOG

Public API Change Record

This log records actual interface changes. There is currently no deprecation or sunset plan; any future announcement will include a specific end date and migration path.

v1 compatibility policy

  • Within v1 we allow additions of optional fields, endpoint documentation and compatible capabilities;
  • removing fields or changing field meanings, stable IDs or default ordering are breaking changes and require a new v2;
  • Published stable IDs (obs_/price_/ev_/pfv_ prefixes) are never reused.

Agent interfaces are generally available: REST / MCP / Skill / RSS
