# Every change on a project, on the record

Studio now writes down what changed on a project, who changed it, and what it
looked like before.

## The project audit log

Every create, update, and delete is recorded against the entity it touched —
stories, epics, bugs, sprints, requirements, wiki pages and folders, canvas
diagrams, resources, meetings, test suites, cases, plans and environments,
project members, API keys, comments, and project context. The log lives on the
project and can be filtered by entity type, action, and actor.

Actors are recorded by kind, not just by name. A change made by a teammate, by
Helix, by an MCP client, or by a scheduled system job each carries its own
label, so an unexpected edit is traceable to the thing that made it rather than
to whoever happened to own the session.

Sensitive values — API keys, tokens, credentials — are redacted before the entry
is written, and the log entry is committed in the same transaction as the change
itself. An action that fails leaves no audit row, and an action that succeeds
cannot silently skip one.

## Also in this release

- **Universal integration read endpoints.** External tooling can read the core
  project entities through a single consistent set of endpoints instead of
  reaching for per-feature APIs.
- **Scoped MCP toolsets.** A `toolsets` query parameter lets an MCP client load
  only the tool groups it needs rather than all of them, which keeps smaller
  clients well inside their tool limits.
- **Setup guidance for claude.ai and ChatGPT** in the MCP docs, with client
  pages now linking straight to toolset configuration.
- Docs pages support Loom embeds and shareable tab URLs, so a link can point at
  the exact tab you were reading.
