This page describes how to create a new minor release of EMQX Enterprise Edition and test that hot upgrading from the previous minor release to the current one works. The steps to do the same for EMQX Community Edition should be very similar.

Identify which internal apps have changed after the previous minor release
Bump the version number in the APP_NAME.app.src files for the apps that have changed. For example, if the emqx_rule_actions has changed, then bump the version number under the vsn property in lib-ee/emqx_rule_actions/src/emqx_rule_actions.app.src. If the previous version number was "4.4.5" then the new one should be "4.4.6".
Bump the version number for the main EMQX app. This means bumping the version number under the vsn property in the file src/emqx.app.src. If the previous version number was "4.4.5" then the new one should be "4.4.6".
Bump the version numbers in include/emqx_release.hrl. The version numbers in include/emqx_release.hrl should be the same as in `src/e

Erlang Experimental Language Features Investigation Report

Erlang currently does not support selectively using experimental language features that are not officially part of the Erlang language. Having support for doing so can help users try out and experiment with a potential extension to the language without adding this extension to the main language. This report looks into how support for selectively including experimental language features looks in other languages and how such support might look in Erlang.
