Release Support
Review the following information about supported release versions for Gloo Edge Enterprise and Gloo Edge OSS (open source).
Supported versions
Gloo Edge Enterprise offers n-3 patching support for bug and critical security fixes. In other words, the current release and the three previous releases are supported.
| Gloo Edge | Kubernetes | Envoy | Helm | Istio† |
|---|---|---|---|---|
| 1.17.x | 1.25 - 1.29 | v3 xDS API | >= 3.12 | 1.16 - 1.22 |
| 1.16.x | 1.24 - 1.28 | v3 xDS API | >= 3.12 | 1.14 - 1.20 |
| 1.15.x | 1.23 - 1.27 | v3 xDS API | >= 3.11 | 1.13 - 1.18 |
| 1.14.x | 1.23 - 1.25 | v3 xDS API | >= 3.8 | 1.13 - 1.18 |
† Istio versions: Istio must run on a compatible version of Kubernetes. For example, Istio 1.22 is tested, but not supported, on Kubernetes 1.26. For more information, see the Istio docs. If you want hardened n-4 versions of Istio for particular requirements such as FIPS, consider using Gloo Mesh Enterprise, which includes ingress gateway and service mesh components.Release cadence
Gloo Edge Enterprise releases are built on the OSS codebase and typically follow the equivalent Gloo Edge OSS release. The OSS version is always released as the latest build, while Enterprise version is always released as the first stable build of that version. For example, the latest build of Gloo Edge OSS is 1.15.33, while the latest stable build of Gloo Edge Enterprise is 1.15.22.
Stable builds for both Gloo Edge Enterprise and OSS are released as minor versions approximately every three months. A stable branch for a minor version, such as 1.14, is tagged from main, and stable builds for both Enterprise and OSS are supported from that branch.
Release development
Beta release process
New features for Gloo Edge Enterprise and OSS are always developed on main. For Enterprise, new features are often released as beta builds of the latest Gloo Edge Enterprise version. You can use these beta builds to test new features, or wait until the feature is released with the next stable Enterprise minor version. For OSS, new features for the latest version are released as patches off of main.
Stable release process
Development of a quality stable release on main typically follows this process:
- New feature development is suspended on
main. - Release candidates are created, such as
1.14.0-rc1,1.14.0-rc2, and so on. - A full suite fo tests is performed for each release candidate. Testing includes all documented workflows, a test matrix of all supported platforms, and more.
- Documentation for that release is prepared, vetted, and staged.
- The stable minor version is released.
- Feature development on
mainis resumed.
Additional support information
Kubernetes
Gloo Edge Enterprise is supported and tested for the latest Kubernetes version and all Kubernetes versions released up to 1 year before the latest version.
Envoy
Officially, Gloo Edge Enterprise offers support for n-1 of Envoy community releases. In specific support situations, fixes can be backported to n-2 or more without bumping the Envoy minor version. In other words, a fix can be developed based on the code that you deployed within the n-2 release timeframe.
Gloo Edge
New features are not developed on or backported to stable branches. However, critical patches, bug fixes, and documentation fixes are backported to all actively supported branches.
