<Update label="v2.2.0" description="14 Sept 2026">
  `new-actions`

  Enabled Data Sync on annotation tags, lookup tables, schemas, and users, groups, and organizations for scheduled full record syncs.

  <AccordionGroup>
    <Accordion title="Changed · 6 actions updated">
      `mixpanel_list_annotation_tags`, `mixpanel_list_lookup_tables`, `mixpanel_list_schemas`, `mixpanel_unified_list_groups`, `mixpanel_unified_list_organizations`, `mixpanel_unified_list_users`

  </AccordionGroup>
</Update>

<Update label="v2.1.2" description="1 Sept 2026">
  `bug-fix`

  Lookups for missing users, roles, groups, and organizations now return a not-found error.

  </AccordionGroup>
</Update>

<Update label="v2.1.1" description="19 Aug 2026">
  `behavioral-bug-fix`

  Clarified the Set and Union list-property write actions (profiles and groups) so Set overwrites a property's full value — replacing a whole list with the exact array provided — while Union only extends an existing list, preserving current items and ignoring duplicates.

    <Accordion title="Changed · 4 actions updated">

  </AccordionGroup>
</Update>

<Update label="v2.1.0" description="18 Aug 2026">
  `bug-fix`

  Delete User Profile and Delete Group now return Mixpanel's real result instead of always reporting "deleted successfully", so a failed deletion surfaces the actual error. Clarified the profile and group write action descriptions to state that a Project Token must be set on the connection, and improved the Import Events guidance.

    </Accordion>
  </AccordionGroup>
</Update>

<Update label="v2.0.0" description="13 Aug 2026">
  `bug-fix` `breaking`

  Fixed the profile, group, and identity write actions that required an unknowable project token in each request and could silently fail; they now use a new Project Token connection field and target a single record directly. Removed the redundant batch group and profile update actions.

</Update>

<Update label="v1.1.2" description="4 Aug 2026">
  `guide-changes`

  Added portal screenshots to the Service Account connection guide and corrected the settings navigation, Create Service Account form fields, and where to find the Project ID, Organization ID, and Data Residency.
</Update>

<Update label="v1.1.1" description="4 Aug 2026">
  `bug-fix`

  Fix Data Residency region check at connection time. Removed the lookup-tables action from the connection test because it worked on both US and EU hosts and let accounts connect with the wrong region selected. Now connecting with the wrong region correctly fails.
