Erlang is a general-purpose, concurrent, functional programming language, and a garbage-collected runtime system. The term Erlang is used interchangeably with Erlang/OTP, or Open Telecom Platform (OTP), which consists of the Erlang runtime system, several ready-to-use components (OTP) mainly written in Erlang, and a set of design principles for Erlang programs.
We provide different releases and apply security updates on a regular basis. Currently, these versions are available: 20, 21 and 22. All versions include Elixir and Mix, a build tool that allows you to easily create projects, manage tasks, run tests and more.
If you don’t select a certain version, our default will be used. We decided to default to version 21
