# Electron Releases
|
|
|
|
Electron frequently releases major versions alongside every other Chromium release.
|
|
This document focuses on the release cadence and version support policy.
|
|

**Notes:**
|
|
|
|
* The `-alpha.1`, `-beta.1`, and `stable` dates are our solid release dates.
|
|
* We strive for weekly alpha/beta releases, but we often release more than scheduled.
|
|
* All dates are our goals but there may be reasons for adjusting the stable deadline, such as security bugs.
|
|
|
|
**Historical changes:**
|
|
|
|
* Since Electron 5, Electron has been publicizing its release dates ([see blog post](https://electronjs.org/blog/electron-5-0-timeline)).
|
|
* Since Electron 6, Electron major versions have been targeting every other Chromium major version. Each Electron stable should happen on the same day as Chrome stable ([see blog post](https://www.electronjs.org/blog/12-week-cadence)).
|
|
* Since Electron 16, Electron has been releasing major versions on an 8-week cadence in accordance to Chrome's change to a 4-week release cadence ([see blog post](https://www.electronjs.org/blog/8-week-cadence)).

## Version support policy
|
|
|
|
:::info
|
|
|
|
Beginning in September 2021 (Electron 15), the Electron team
|
|
will temporarily support the latest **four** stable major versions. This
|
|
extended support is intended to help Electron developers transition to
|
|
the [new 8-week release cadence](https://electronjs.org/blog/8-week-cadence),
|
|
and will continue until the release of Electron 19. At that time,
|
|
the Electron team will drop support back to the latest three stable major versions.
|
|
|
|
:::
|
|
|
|
The latest three *stable* major versions are supported by the Electron team.
|
|
For example, if the latest release is 6.1.x, then the 5.0.x as well
|
|
as the 4.2.x series are supported. We only support the latest minor release
|
|
for each stable release series. This means that in the case of a security fix,
|
|
6.1.x will receive the fix, but we will not release a new version of 6.0.x.
|
|
|
|
The latest stable release unilaterally receives all fixes from `main`,
|
|
and the version prior to that receives the vast majority of those fixes
|
|
as time and bandwidth warrants. The oldest supported release line will receive
|
|
only security fixes directly.
|
|
|
|
### Breaking API changes
|
|
|
|
When an API is changed or removed in a way that breaks existing functionality, the
|
|
previous functionality will be supported for a minimum of two major versions when
|
|
possible before being removed. For example, if a function takes three arguments,
|
|
and that number is reduced to two in major version 10, the three-argument version would
|
|
continue to work until, at minimum, major version 12. Past the minimum two-version
|
|
threshold, we will attempt to support backwards compatibility beyond two versions
|
|
until the maintainers feel the maintenance burden is too high to continue doing so.
|
|
|
|
### End-of-life
|
|
|
|
When a release branch reaches the end of its support cycle, the series
|
|
will be deprecated in NPM and a final end-of-support release will be
|
|
made. This release will add a warning to inform that an unsupported
|
|
version of Electron is in use.
|
|
|
|
These steps are to help app developers learn when a branch they're
|
|
using becomes unsupported, but without being excessively intrusive
|
|
to end users.
|
|
|
|
If an application has exceptional circumstances and needs to stay
|
|
on an unsupported series of Electron, developers can silence the
|
|
end-of-support warning by omitting the final release from the app's
|
|
`package.json` `devDependencies`. For example, since the 1-6-x series
|
|
ended with an end-of-support 1.6.18 release, developers could choose
|
|
to stay in the 1-6-x series without warnings with `devDependency` of
|
|
`"electron": 1.6.0 - 1.6.17`.
