Version Support Policy

Overview

This document applies to the following products:

  • ngrok Agent

Versioning​

We follow Semantic Versioning, and limit breaking changes to major upgrades.

Cadence​

Our typical minor release happens at least quarterly while our typical patch release is at least monthly. Critical bug fixes may cause a more immediate release outside of the normal cadence. We also aim not to make releases during major US holiday periods.

Support Period​

In accordance with our 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 us for additional details.
