This page lists the status, timeline and policy for currently supported releases. Supported releases of Istio include releases that are in the active maintenance window and are patched for security and bug fixes. Subsequent patch releases on a minor release do not contain backward incompatible changes.

We produce new builds of Istio for each commit. Around once a quarter, we build a minor release and run through several additional tests as well as release qualification. We release patch versions for issues found in minor releases.
The various types of releases represent a different product quality level and level of assistance from the Istio community. In this context, support means that the community will produce patch releases for critical issues and offer technical assistance. Separately, 3rd parties and partners may offer longer-term support solutions.
|Type||Support Level||Quality and Recommended Use|
|Development Build||No support||Dangerous, may not be fully reliable. Useful to experiment with.|
|Minor Release||Support provided until 6 weeks after the N+2 minor release (ex. 1.11 supported until 6 weeks after 1.13.0 is released)|
|Patch||Same as the corresponding Minor release||Users are encouraged to adopt patch releases as soon as they are available for a given release.|
|Security Patch||Same as a Patch, however, it will not contain any additional code other than the security fix from the previous patch||Given the nature of security fixes, users are strongly encouraged to adopt security patches after release.|
You can find available releases on the releases page, and if you’re the adventurous type, you can learn about our development builds on the development builds wiki. You can find high-level releases notes for each minor and patch release here.
Our naming scheme is as follows:
<minor> is increased for each release, and
<patch> counts the number of patches for the
<minor> release. A patch is usually a small change relative to the
