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.

1. Identify which internal apps have changed after the previous minor release
2. 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".
3. 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".
4. 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

How the J Script Works

Going line by line:

b =: >: i. 9 9 9

This generates a 9 by 9 by 9 array with all values from 1 to 729. We can choose what each axis represents: I decided that each table is all of the boolean variables for one number, and the rows and columns map to sudoku rows and columns. For example:
