# Changelog

Release notes for the One product documentation. Each section describes what an
installed release documents; it is not a claim that a capability is available
in your exact release. The owning package API, README, and tests remain the
implementation evidence.

## [Unreleased]

- Reorganize the site around one progressive journey: Start, Author, Design,
  Implement, Ship & operate, Extend & govern, Examples, Operations examples,
  and Reference.
- Add advanced references for [the lock](/one/reference/lock),
  [diagnostics and output](/one/reference/diagnostics),
  [profiles and assurance](/one/reference/profiles), and
  [One Contract Schema](/one/reference/ocs).
- Add [Benchmark and performance evidence](/one/platform/benchmark),
  [Cost and budgets](/one/platform/cost), and
  [Packaging and boundaries](/one/platform/packaging).
- Add [Experience and presentation](/one/model/experience) and
  [Ported data plane](/one/model/ported-data).
- Add [Tests, simulations, and fixtures](/one/authoring/testing) and
  [the local development loop](/one/guides/local-development).
- Add a [declaration-head vocabulary](/one/authoring/product#declaration-heads-are-domain-owned)
  that separates implemented heads from illustrative target syntax.
- Normalize plan and operation references, label deferred capabilities, and
  merge overlapping recipe pages into their governing guides.
