Release History

This page lists the firmware releases for your Cloud Voice phone system, organized by year and ordered with the most recent build first. Use it to see when a build shipped and to open the release note for any build that has one.

Note

Firmware is the built-in software that runs your Cloud Voice phone system. Each release updates that software with new features, improvements, and fixes. Select a linked version to open its full release note, which describes exactly what changed in that build.

How to read a release entry

Before you browse the tables below, it helps to know what each field means.

Release Date: The day the firmware build was published.

Release Version: The version label together with its release stage. Cloud Voice ships builds in two stages:

• V{version}-Beta: An early (pre-release) build that introduces new features and improvements. It is intended for early adopters who want to try the latest capabilities ahead of the general release.
• V{version}-GA: The finalized build, validated and ready for use in a production environment.

In these labels, V{version} is the version number written in the format VXX.X (for example, V22.3). Beta marks a build that is available for testing and evaluation, while GA (General Availability) marks a build that is fully validated for general use.

Caution

Beta builds are for testing and evaluation only. Do not install a Beta build on a production system that is handling live calls, because early builds can behave unpredictably. For everyday service, always choose a GA build.

Tip

When you upgrade a customer’s system, pick the newest GA build unless you are deliberately testing a specific Beta feature.

Firmware Version: The firmware build number, written in the format 84.X.X.X (for example, 84.21.0.117).

Base Version: The earlier version that the current release is built on.

Note

The Base Version tells you which build the release was assembled from. It helps you trace the upgrade path from one build to the next when you are planning or troubleshooting an update.
