# Angular Release Schedule

This document contains historic record of past Angular releases and future release schedule.

The purpose of this document is to assist coordination among the Angular team, Angular contributors, Angular application teams, and Angular community projects.

We'll keep this doc up to date when unplanned releases or other schedule changes occur.


## Schedule Caveats and Exceptions

The dates listed here are approximate – last minute issues, team or community events, etc. can cause us to release a few days sooner or later.

This page contains only planned and past unplanned releases.
Due to serious regressions or other important reasons we reserve the right to release an unplanned patch or minor release.
In such case, we'll update this document accordingly.

The dates are just a guidance and might be adjusted slightly if necessary.

## Tentative Schedule Until September 2017

## Tentative Schedule After September 2017

 Date                   | Stable Release | Compatibility`*`
 ---------------------- | -------------- | ----------------
 March 2018             | 6.0.0          | ^5.0.0
 September/October 2018 | 7.0.0          | ^6.0.0

 `*` The goal of the backwards compatibility promise, is to ensure that changes in the core framework and tooling don't break the existing ecosystem of components and applications and don't put undue upgrade/migration burden on Angular application and component authors.


## More Info & Resources

In [September 2016 we announced](http://angularjs.blogspot.com/2016/10/versioning-and-releasing-angular.html) that Angular is fully adopting [semantic versioning](http://semver.org/) and that we'll be releasing patch versions on a weekly basis (~50 per year), minor versions monthly for 3 months following a major version release, and every 6 months we'll release a major version that will be backwards compatible with the previous release for most developers, but might remove APIs that have been deprecated two major versions ago (6 or more months ago).

In [December 2016 we clarified this message](http://angularjs.blogspot.com/2016/12/ok-let-me-explain-its-going-to-be.html), and provided additional details about the plans to release Angular 4.0.0 in March 2017.
This document contains updates to the schedule that happened since then.
-												docs(release-schedule): add release schedule doc (#13827)

While authoring this document we agreed to pushing off the 4.0.0 release by one week by adding one more RC week (compared to the original plan).
We announced that RC would take 1 month, but then I did the calendar math incorrectly.
This schedule change will give community more time to test the release before we call it done and report any potential regression or unforeseen issues.
