 *** WooCommerce API Manager PHP Library for Plugins and Themes Changelog ***
 
+2021.07.09 - version 2.8.1
+ * Fix: Warning: Trying to access array offset on value of type bool. PHP warning fixed by checking if the API Key string is not empty before using the string to access the api_key element in an array.
+
 2020.12.17 - version 2.8
  * New: Updated so both Parent and Child themes can have activated API Keys at the same time, and can do a theme update at the same time, provided each have had their API Keys activated and remain activated. See online doc for correct setup.
  * New: Auto-Updates now available for Plugins, and Parent and Child Themes, as was introduced in WP 5.5.
