Changelog
Product and API updates for Matrices.
This page is the developer-facing log of changes to the Matrices platform and
runtime APIs: new endpoints, changed request shapes, new built-in tool
namespaces, authentication behavior, permission and credential
changes, and migration notes.
Treat the API Reference as the source of truth for
exact routes and schemas. The concept guides explain the mental model; this page
records what changed and why it matters to anyone building on the API. Keep
internal implementation detail out unless it changes what a customer should do.
