WooCommerce Beta Tester allows you to try out new versions of WooCommerce before they are officially released.
Use with caution, not on production sites. Beta releases may not be stable.
After activation, you’ll be able to choose an update channel:
Beta – Update to beta releases, RC, or stable, depending on what is newest. 
Release Candidate – Update to RC releases or stable, depending on what is newest. 
Stable – No beta updates. Default WordPress behavior.
These will surface pre-releases via automatic updates in WordPress. Updates will replace your installed version of WooCommerce.
Note, this will not check for updates on every admin page load unless you explicitly tell it to. You can do this by clicking the “Check Again” button from the WordPress updates screen or you can set the WC_BETA_TESTER_FORCE_UPDATE to true in your wp-config.php file.
You can get to the settings and features from your top admin bar under the name WC Beta Tester.
