Release version 1.1.15 - Fix duplicate settings page

Fixed settings page appearing twice in WooCommerce settings due to double instantiation of WC_TPP_Settings class.

**Issue:**
- Settings page rendered twice on same page
- WC_TPP_Settings class instantiated twice: once automatically in settings file, once via admin class include

**Fix:**
- Removed conditional wrapper `if (class_exists('WC_TPP_Settings'))` from settings return statement
- Settings class now only instantiated when admin class includes the file via `return new WC_TPP_Settings();`
- Restored v1.1.2 pattern for settings file

**Files Modified:**
- includes/class-wc-tpp-settings.php (simplified return statement)

+## [1.1.15] - 2025-12-22
+
+### Fixed
+
+- Settings page rendering twice in WooCommerce settings
+- Duplicate instantiation of WC_TPP_Settings class causing double rendering
+
+### Technical Details
+
+- Removed conditional `if (class_exists('WC_TPP_Settings'))` wrapper from settings return statement
+- Settings class now only instantiated via `return new WC_TPP_Settings();` when included by admin class
+- Matches v1.1.2 pattern where settings file returns instance without automatic instantiation
+- Prevents double registration in WooCommerce settings pages array
+
+## [1.1.14] - 2025-12-22
+
+### Fixed
+
+- **CRITICAL:** Plugin completely non-functional in v1.1.8-1.1.13 - no settings, no frontend, no backend
+- Classes never instantiated due to incorrect initialization pattern introduced in v1.1.8
+- Restored v1.1.2 pattern: classes auto-instantiate when files are included
+- All plugin functionality now working: settings page, product meta boxes, frontend display, cart integration
+
+### Changed
+
+- Reverted to direct class instantiation pattern from v1.1.2 (last known working version)
+- Removed `init_classes()` method and `woocommerce_loaded` hook approach from v1.1.8
+- Each class file now instantiates itself with `new ClassName()` at end of file
+- Simplified plugin initialization for better reliability
+
+### Technical Details
+
+- Restored class instantiation in all 5 component files:
+  - `class-wc-tpp-admin.php`: Added `new WC_TPP_Admin();` after class declaration
+  - `class-wc-tpp-product-meta.php`: Added `new WC_TPP_Product_Meta();` after class declaration
+  - `class-wc-tpp-frontend.php`: Added `new WC_TPP_Frontend();` after class declaration
+  - `class-wc-tpp-cart.php`: Added `new WC_TPP_Cart();` after class declaration
+  - `class-wc-tpp-settings.php`: Already has instantiation via return statement
+- Removed `init_classes()` method from main plugin class
+- Removed `woocommerce_loaded` hook that delayed class instantiation
+- Classes now instantiate immediately when `require_once` loads them
+- All `class_exists()` guards remain in place for redeclaration protection
+
+## [1.1.13] - 2025-12-22
+
+### Fixed
+
+- **CRITICAL:** Class redeclaration errors for all plugin component classes affecting version 1.1.12
+- Fatal errors "Cannot redeclare class WC_TPP_Admin", "Cannot redeclare class WC_TPP_Product_Meta", "Cannot redeclare class WC_TPP_Frontend", "Cannot redeclare class WC_TPP_Cart", "Cannot redeclare class WC_TPP_Settings"
+- Plugin functionality completely broken in v1.1.12 - no settings page, no frontend display, no backend controls
+- All plugin features now working correctly after adding class guards
+
+### Technical Details
+
+- Wrapped all 5 plugin component class declarations in `class_exists()` checks:
+  - `WC_TPP_Admin` (includes/class-wc-tpp-admin.php)
+  - `WC_TPP_Product_Meta` (includes/class-wc-tpp-product-meta.php)
+  - `WC_TPP_Frontend` (includes/class-wc-tpp-frontend.php)
+  - `WC_TPP_Cart` (includes/class-wc-tpp-cart.php)
+  - `WC_TPP_Settings` (includes/class-wc-tpp-settings.php)
+- Completes comprehensive redeclaration protection started in v1.1.9-1.1.12
+- All functions, constants, and classes now fully protected against redeclaration
+- Plugin now activates and functions correctly without fatal errors
+
