# MongoDB Atlas Changelog

> Release history for the MongoDB Atlas connector. Each version lists what changed and which actions were affected.

<Card title="MongoDB Atlas connector" icon="arrow-left" href="/connectors/mongodb" horizontal>
  Back to the connector overview, authentication methods, and actions.

<Update label="v1.2.0" description="11 Sept 2026">
  `new-feature`

  Added Data Sync support for List Projects, List Organizations, List Unified Organizations, List Unified Users, List Unified Groups, and List Unified Roles, so these resources can be synced into StackOne on a schedule and read without calling MongoDB Atlas. All six run as a full refresh on every sync, because the Atlas Administration API offers no way to filter by last-updated time.

<Update label="v1.1.2" description="1 Sept 2026">
  `bug-fix`

  Project ID fields now warn against passing a project name or label instead of the 24-character ID, and create custom database role clarifies that a role must grant at least one privilege (an action or an inherited role).

<Update label="v1.1.0" description="20 Aug 2026">
  `new-actions`

  Added unified IAM actions for organization users, teams, roles, and project-scoped access, mapped from MongoDB Atlas's org and project user, team, and role-assignment endpoints. List actions request pages until Atlas returns an empty page, so results are not capped at a fixed page count. Organization-scoped listings ask for the organization when several are visible to the connection, and user lists accept an optional organization filter.

<Update label="v1.0.2" description="24 Jul 2026">
  `bug-fix`

  Clearer action descriptions so agents get two calls right the first time — deleting or reading an IP access list entry for a CIDR range (the slash must be written as %2F) and creating or updating a custom database role (now explains the fields for inherited roles and privilege actions).

<Update label="v1.0.1" description="22 Jul 2026">
  `connection-guide`

  Update the OAuth 2.0 Service Account connection guide.
</Update>

<Update label="v1.0.0" description="20 Jul 2026">
  `new-connector`

  Initial MongoDB Atlas connector with 60 actions across 14 resources (projects, clusters, organizations, database users, custom roles, alerts, backups, IP access list, teams, API keys, flex clusters, and events). OAuth 2.0 Service Account authentication.
