## 更新日志

#### [2.0.0] – 2026-01-20

**Major Release – Context-Based Reply-To Routing**

This major release combines multiple enhancements including context-based email 
routing, security improvements, and Reply-To name support.

**Added**

 * Context-based Reply-To routing – Configure different Reply-To addresses for different
   types of emails.
 * Six email contexts: Default, Authentication & Security, Comments & Moderation,
   Users & Registration, System & Updates, WooCommerce.
 * WooCommerce tab only visible when WooCommerce plugin is active.
 * Intelligent context detection using backtrace analysis.
 * Modern tabbed user interface using WordPress native nav-tab-wrapper.
 * Visual status indicators on each tab (green = active with email, red = inactive
   or no email).
 * Legend explaining status indicators for easy understanding.
 * Enable/disable toggle for each context (except Default which is always active).
 * Fallback chain: Specific context  Default context  Legacy settings.
 * Detailed descriptions and examples for each context in the admin UI.
 * Reply-To Name field – Now you can specify a name to display with the Reply-To
   email address (e.g., “Support Team [support@example.com](https://cn.wordpress.org/plugins/replyto/support@example.com?output_format=md)“).
 * Name sanitization with header injection prevention.
 * Length validation for name field (255 characters maximum).
 * Created uninstall.php for proper cleanup of plugin data on uninstallation.
 * Implemented logging of configuration changes for security auditing (requires 
   WP_DEBUG_LOG).

 * Added success/error messages for better user feedback.

**Changed**

 * Complete rewrite of settings page with modern tab-based interface.

   wp_mail_replyto_contexts).
 * Improved sanitization and validation for multiple contexts.
 * Enhanced logging with context information in debug mode.
 * Email header construction now supports both name and email format.
 * Updated sanitize callback to use custom function with enhanced validation.

 * Enhanced input sanitization with multiple validation layers.

   more efficient).

   updates, WooCommerce emails.
