# Erlang Version Requirements

## Introduction {#intro}

This guide covers Erlang/OTP version requirements, [Erlang version support policy](#supported-version-policy),
a RabbitMQ/Erlang [compatibility matrix](#compatibility-matrix),
version-specific notes and [ways of provisioning](#erlang-repositories) recent Erlang/OTP releases.

:::warning

Erlang 28 is **only supported for brand new clusters**: upgrades of clusters running RabbitMQ with Khepri on Erlang 27
to Erlang 28 can run into a known issue that affects mixed-version clusters and thus rolling upgrades.

:::

## Supported Erlang Version Policy {#supported-version-policy}

The fully supported series is Erlang `27.x`, with `28.x` partially supported (see below).

### Erlang 29 Support

Erlang 29 is **not supported** by RabbitMQ 4.3.

### Erlang 28 Support

Erlang 28 is **partially supported** by RabbitMQ 4.3.x: upgrades of clusters running Khepri have known issues
directly related to the breaking changes in Erlang 28 that equally affect Erlang 29.

### Erlang 27 Support

Erlang 27 is supported.

### Erlang 26 Support

Erlang 26 has reached end of life and is
**no longer supported**.

## RabbitMQ and Erlang/OTP Compatibility Matrix {#compatibility-matrix}

The table below provides an Erlang compatibility matrix of currently supported RabbitMQ release series.
For RabbitMQ releases that have reached end of life, see [Unsupported Series Compatibility Matrix](#eol-series).

As a guideline, most recent minor and patch versions of each supported Erlang/OTP series
are recommended.

## Provisioning Latest Erlang Releases {#erlang-repositories}

Most recent versions can be obtained from a number of sources:

 * [Team RabbitMQ Debian repositories](install-debian#apt-repositories) or [Launchpad](install-debian#apt-launchpad-erlang)
 * [Zero dependency Erlang RPM](https://github.com/rabbitmq/erlang-rpm) from Team RabbitMQ, also available [from a `dnf`/`yum` repository](install-rpm#dnf-repositories)
 * As part of [RabbitMQ Docker image](https://github.com/docker-library/rabbitmq/)
 * [erlang.org](https://www.erlang.org/downloads#prebuilt) provides binary builds of patch releases for Windows
 * Building from source with [kerl](https://github.com/kerl/kerl)

## Installing Erlang/OTP on Debian or Ubuntu {#debian}

Standard Debian and Ubuntu repositories provide Erlang/OTP but it is
heavily sliced and diced into dozens of packages. In addition, unless the system
has backport repositories enabled, the versions tend to be quite old.
See [Debian and Ubuntu installation guide](./install-debian) for
more information on the essential packages, dependencies, and alternative apt repositories.

## Installing Erlang/OTP on RHEL, CentOS and Fedora {#redhat}

There are multiple RPM packages available for Erlang/OTP. The recommended option is
the [zero-dependency Erlang RPM](https://github.com/rabbitmq/erlang-rpm) from the RabbitMQ team.
It closely follows the latest Erlang/OTP patch release schedule.

See [CentOS, RHEL and Fedora installation guide](./install-rpm) for more information on the available options.


## Erlang Versions in Clusters {#clusters}

It is **highly recommended** that the same major version of
Erlang is used across all [cluster nodes](./upgrade#rabbitmq-erlang-version-requirement)
(e.g. `27.x`).

RabbitMQ will check for internal protocol versions of
Erlang and its distributed libraries when a node joins a
cluster, refusing to cluster if there's a potentially
incompatible combination detected.

Outside of a reasonably long upgrade time window, it is
recommended that all nodes use exactly the same version of Erlang.


## Building Erlang from Source {#building-from-source}

If a sufficiently recent Erlang package is not available for a given operating system,
Erlang/OTP can be [built from source](http://www.erlang.org/doc/installation_guide/INSTALL.html).
This requires a build environment that satisfies the Erlang build dependencies, such as a
modern OpenSSL version.

[kerl](https://github.com/kerl/kerl) makes building Erlang/OTP releases from
source, including specific tags from GitHub, a much more pleasant experience.
