    137 dated entries. The most recent 25 are consecutive Fridays — August 21, August 14,
    August 7, July 31, July 24, July 17, July 10, July 3, June 26, June 19, June 12, June 5,

    March 20, March 13, March 6 (all 2026). This is a genuinely maintained log, not an
    occasional post.
  structure: >-
    Each entry is an <Update label="<Month D, YYYY>"> block with optional "What's New" and
    "Changes, Improvements, and Bug Fixes" sections, the latter split into General and
    Connectors. Connector lines are tagged (New) / (Update) / (Removed) / (Deprecated).
  versioning: >-
    Connect AI is continuously delivered and carries no product version number in the log.
    The APIs themselves version in the path: /api/v1/admin for the Management API,
    info.version "v1" on the REST, OData and OpenAPI specs.
  scope: >-
    Covers the Connect AI platform, its APIs and its 500+ connectors in one stream. There is
    no separate API-only changelog, so an API consumer reads platform noise to find contract
    changes.

  breaking: false
  highlights:
  - >-
    MCP source tools now expose object-typed parameters as JSON objects in the tool schema.
    Previously they were exposed as strings, so MCP clients passed values as JSON-encoded
    text instead of structured objects — a real agent-facing contract fix.
  - Fixed MCP Toolkit tools failing to resolve the backing connection under a service account session.
  - On-premises OAuth for API connections now works through Connect Gateway.
  - The API Connector gained a configurable OAuth Scope advanced setting.
  removals:
  - 'Microsoft Access (Removed): connector no longer available as a data source.'
- date: '2026-08-14'
  breaking: false
  highlights:
  - Data Copilot renamed to Playground, with guided onboarding for Jira, GitHub and Slack.
  - Connection validation now runs only on Test Connection, not before every query.
  - 'Query Execution Engine fixes: % wildcard catalog names, INSERT INTO SELECT with aliases and multi-connection JOINs.'
  additions:
  - 'Anaplan (New), Coda (New), SAP Business Warehouse (New), ServiceDesk Plus (New), Suadeo (New).'
  - >-
    Dynamics 365 Business Central (Update): INSERT no longer silently ignores unknown column
    names — it returns an error instead of dropping data without warning.
- date: '2026-08-07'
  breaking: true
  highlights:
  - >-
    The machine-to-machine (M2M) application type has been REMOVED from OAuth Apps. Callers
    must move to service accounts for automated authentication. This is the clearest
    breaking auth change in the recent window.
  - AI responses in Data Copilot and AI Assistant now stream incrementally.
notable_older:
- note: >-
    Connector-level breaking changes recur through the log and are the practical source of
    breakage for CData consumers, because a connector change alters the shape of the data a
    query returns. Examples read from the log: Shopify's default API schema moved from
    2024-07 to 2025-07 with schemas before 2025-01 no longer supported; QuickBooks Online
    moved to version 26 for Intuit's API changes, altering null values, row ordering, column
    titles and empty sections and deprecating the GroupBy parameter; Xero now requires PKCE
    with other authentication options removed; Smartsheet's useLegacyAPI now defaults to
    false ahead of the legacy API sunset; Parquet and Bing Search connectors were removed
    and deprecated respectively; sub-account API access was removed for Connect AI Embed
    administrators.
