# Changelog

> Latest Nitro Sign Enterprise Verified API updates, new endpoints, and announcements.

Releases roll out to tenant deployments gradually, so features introduced in a newer release are
marked *Available as of NSEV vX.Y* throughout these docs. This page tracks changes to the API and
its documentation - for full product release notes per NSEV version, see the
[NSEV release overview](https://connectivegroup.my.site.com/s/article/NSEV-Release-Overview?language=en_US).

<Update label="July 2026" tags={["v8.4"]}>
  A ground-up revamp of the Nitro Sign Enterprise Verified developer documentation: a rebuilt API
  reference for NSEV v8.4: covering packages, documents, actors, elements, stakeholders,
  substitutes, bulk actions, audit trails, users, and configuration. Plus new getting-started
  guides, tutorials, concept pages, and integration guides.
</Update>

<Tip>
  **Which version does your tenant run?** Ask the version endpoint - no authentication required:

  ```bash theme={null}
  curl https://your-tenant.sign.gonitro.com/esig/webportalapi/v4/version
  ```

  ```json theme={null}
  { "ProductVersion": "8.4.4", "FileVersion": "8.4.4-ef8f69b" }
  ```

  The first two components of `ProductVersion` are the NSEV release - here, v8.4. If a feature
  marked *Available as of NSEV vX.Y* is newer than the version your tenant runs,
  [contact Nitro support](https://connectivegroup.my.site.com/s/contactsupport?language=en_US)
  to ask about the upgrade timeline.
