## Platform support

Each Electron release provides binaries for macOS, Windows, and Linux.

* macOS (El Capitan and up): Electron provides 64-bit Intel and ARM binaries for macOS. Apple Silicon support was added in Electron 11.
* Windows (Windows 7 and up): Electron provides `ia32` (`x86`), `x64` (`amd64`), and `arm64` binaries for Windows. Windows on ARM support was added in Electron 5.0.8.
* Linux: The prebuilt binaries of Electron are built on Ubuntu 18.04. They have also been verified to work on:
* Ubuntu 14.04 and newer
* Fedora 24 and newer
* Debian 8 and newer

## 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`.

Since Electron 8, stabilization branches are always **major** version lines, and named against the following template `$MAJOR-x-y` e.g. `8-x-y`. Prior to that we used **minor** version lines and named them as `$MAJOR-$MINOR-x` e.g. `2-0-x`.

We allow for multiple stabilization branches to exist simultaneously, one for each supported version. For more details on which versions are supported, see our [Electron Release Timelines](./electron-timelines.md) doc.

## Supported Platforms

Following platforms are supported by Electron:

### macOS

Only 64bit binaries are provided for macOS, and the minimum macOS version
supported is macOS 10.11 (El Capitan).

Native support for Apple Silicon (`arm64`) devices was added in Electron 11.0.0.

### Windows

Windows 7 and later are supported, older operating systems are not supported
(and do not work).

Both `ia32` (`x86`) and `x64` (`amd64`) binaries are provided for Windows.
[Native support for Windows on Arm (`arm64`) devices was added in Electron 6.0.8.](windows-arm.md).
Running apps packaged with previous versions is possible using the ia32 binary.

### Linux

The prebuilt binaries of Electron are built on Ubuntu 18.04.

Whether the prebuilt binary can run on a distribution depends on whether the
distribution includes the libraries that Electron is linked to on the building
platform, so only Ubuntu 18.04 is guaranteed to work, but following platforms
are also verified to be able to run the prebuilt binaries of Electron:

* Ubuntu 14.04 and newer
* Fedora 24 and newer
* Debian 8 and newer
* For information on supported releases, see the [Electron Releases](./electron-timelines.md) doc.
* For community support on Electron, see the [Community page](https://www.electronjs.org/community).
* For platform support info, see the [README](https://github.com/electron/electron/blob/main/README.md).
