What’s new

  • The first public architecture pillar is named Studio instead of Governance.
  • Studio is organized around account and access, configuration, standards and assurance.
  • The four public pillars are Studio, Knowledge, Tooling and Memory.
  • Governance remains the correct term for actual responsibilities, policies, rules, assurance processes and data-governance topics.
  • Stable technical identifiers, routes, schemas, protocols, directories and runtime behavior are unchanged.
02

Known limitations

  • This content patch does not add roles, permission enforcement, authentication controls, skills, tools, agents, schemas or hosted capabilities.
  • Your assistant's capabilities and permissions still apply. Workflow delivery is not proof that a requested artifact or action completed.
03

Upgrade and migration

  • No project, record, account or runtime migration is required.
  • Update the open-source plugin or refresh the MCP connection to see the 1.5.1.2 terminology.
