# ngrok Agent Version Support Policy

> Learn about ngrok's version support policy including semantic versioning, release cadence, and support periods.

This document applies to the following products:

* ngrok Agent

## Versioning

ngrok follows [Semantic Versioning](https://semver.org/), and limits breaking changes to major upgrades.

## Cadence

Typical minor releases happen at least quarterly while typical patch releases are at least monthly. Critical bug fixes may cause a more immediate release outside of the normal cadence. ngrok also aims not to make releases during major U.S. holiday periods.

## Support period

In accordance with the release cadence, ngrok will support a minor release for 14 months. Support includes:

* Patches
* Critical Security Fixes

Towards the end of the 14-month support period, the following will happen:

* The two-month upgrade cycle will begin. During the last two months of a support period, the following will apply:
  * No more patches or critical security fixes will occur.
  * Announcements will be made attempting to notify users through the following channels:
    * Via email
    * Via social media
    * Status Page
    * Documentation Page
    * That release’s agent banner

After the two-month upgrade cycle has ended, the following will happen:

* The Agent version will enter end-of-life and will **no longer be able to connect to ngrok's cloud network**. Attempting to connect with an unsupported agent will result in an error message.

## Extended support

Extended support beyond LTS is available to customers on a commercial basis. It includes critical security fixes only. [Contact Support](mailto:support@ngrok.com?subject=Extended%20Support%20Inquiry) for additional details.
