Erlang (server-side) SDK 2.x to 3.0 migration guide

This topic explains the changes in the server-side Erlang SDK 3.0 release and how to migrate to that version.

Overview

This topic explains the changes in the Erlang (server-side) SDK 3.0 release and how to adapt code that uses a 2.x version of the Erlang (server-side) SDK to use version 3.0 or later.

Understanding dependency changes

Version 3.0 requires Gun 2.x. There are no changes to the Erlang SDK API or functionality. However, version 3.0 now requires Gun 2.x.

If your application depends directly on Gun, or if you have other dependencies that use Gun, then you must ensure that they work with Gun 2.x.
