The latest version of the Public Pay Addon Module is 2.5.6, released on November 27, 2018. It added support for FontAwesome 5 icons with fallback for v4 to maintain compatibility with WHMCS 7.6 and newer. All prior releases are documented below in reverse chronological order. This module enables public payment links, client payment history display, PayPal and Coinbase integration, and configurable options for account naming and balance visibility.

Reviewing the changelog before upgrades prevents breakage from WHMCS core changes or library updates. Key themes across releases include payment gateway stability, proper multi-currency handling, SQL and licensing fixes, template and UI compatibility, and removal of retired services. Each update incrementally improves reliability for production environments handling client invoice payments.

#Major Releases

#Version 2.0.0 (July 29, 2015)

This was a complete rewrite for WHMCS 6. It introduced the client's hash ID on the Profile tab, options to specify the receiving PayPal address and payment description to the end user, toggles to enable or disable payment display to clients, and controls for how many payments to show. Templates were cleaned up and performance optimized for large installations. These changes established the foundation for configurable public pay pages used today.

#Version 1.0.4 (June 16, 2014)

Multi-currency support was completed. Hard-coded English text was removed from templates. The ASPnix Google Wallet payment gateway was integrated (later retired by Google and removed in v1.1.7). Success and error message handling for payments was added, payment confirmation emails began including transaction IDs, and licensing checks were hardened to prevent errors. These updates made the module viable for international installations.

#Practical Notes for Administrators

Backup the WHMCS database and module directory before applying any update. Pay particular attention to licensing system changes in versions 2.5.0, 2.1.0, and 1.0.4 as these can interrupt module operation if the core helpers are not aligned. After upgrading, verify PayPal IPN handling, test payments in each active currency, and confirm icon rendering and payment history visibility match your configured options. SQL errors on upgrade or name changes were fixed in 2.0.2 and 2.0.1; confirm the module table schema if you encounter blank pages.

The module no longer supports retired services such as Google Wallet or Dwolla. Use the configured shortcuts menu link added in v2.0.1 for quick access. For template customizations, note the WHMCS 7 styling updates in v2.1.0 and the removal of the Smarty Capitalize plugin dependency in v1.0.5.
