 ** Hellotext for WooCommerce Changelog **
 
+2026-11-07 - version 2.0.2
+
+* Run on PHP 7.4 again: 2.0.0 failed to load there.
+* Declare the supported WordPress, WooCommerce and PHP versions, and compatibility with High-Performance Order Storage.
+* Log failed Hellotext requests to the WooCommerce logs (source "hellotext") when WP_DEBUG is on.
+* Sanitize the checkout link's products and the Webchat card's source before reading them.
+* The release zip is hellotext.zip and installs to the hellotext folder, as the Woo Marketplace requires.
+
 2026-11-06 - version 2.0.1
 
 * Declare WooCommerce as a required plugin: WordPress 6.5 and later only activate Hellotext while WooCommerce is active.
