# Firmware Dependency Reference

The Google Workspace integration gains new capabilities over time, and some of them only work once your system is running a recent enough firmware build. Use this reference to confirm that your Cloud Voice firmware meets the minimum version for the feature you want to use.

:::note
A feature listed below is available only on the firmware version shown for it, or any later release. If a capability is missing from your integration settings, check your firmware version first and update if needed.
:::

:::tip
Firmware version numbers only increase, so a build that meets the newest requirement in this table (currently 84.23.0.24) also covers every earlier feature. You do not need to match each row individually, just make sure you are at or above the version for the newest capability you plan to use.

| Release date | What changed | Minimum firmware |
| --- | --- | --- |
| April 23, 2026 | Refined how extensions are matched to Google users. With **Auto associate Extensions with the Users that share the same email address** enabled, the integration now compares each Google Workspace user's **Primary email** against the email address configured on the Cloud Voice extension. Earlier builds matched against whichever email was pulled from the **Google Field** assigned in the **Email Address** mapping. | 84.23.0.24 or later |
| January 13, 2026 | Added the ability to choose which user fields are synchronized from Google Workspace into Cloud Voice and to map them individually. | 84.21.0.117 or later |
| December 3, 2025 | Added control over how Google users authenticate when signing in to the Cloud Voice App. You can require Single Sign-On (SSO) as the only sign-in method, or let users choose between SSO and the account credentials of their linked extension. | 84.21.0.66 or later |
| May 8, 2025 | Initial release. | 84.19.0.22 or later |
