Release version 1.2.9 - Translation and deletion fixes

## Bugfixes

1. **Price Header Not Translated**
   - Fixed translation function placement in printf statements
   - Changed from printf(__()) to printf(esc_html__())
   - Headers now display in administrator's configured language

2. **Placeholder HTML Entity Encoding**
   - Currency symbols were showing as HTML entities (e.g., €)
   - Removed translation filter from concatenated placeholder strings
   - Placeholders are example values that should not be translated

3. **Variation Pricing Still Not Deletable (Regression)**
   - Despite v1.2.8 fix, edge cases remained due to conditional branching
   - Refactored save logic to be more defensive
   - Always initializes arrays, then unconditionally updates or deletes
   - Guarantees proper cleanup regardless of POST data structure

## Technical Details

- Updated all 6 table headers: printf(esc_html__('Price (%s)', 'wc-tier-package-prices'), ...)
- Removed |__() filter from Twig placeholder concatenations
- Refactored save_variation_pricing_fields() with simplified logic:
  * Initialize arrays at start
  * Populate only if valid POST data exists
  * Always perform update (if !empty) or delete (if empty)
- Added is_array() check for extra safety

## Changed Files

- includes/class-wc-tpp-product-meta.php
- templates/admin/tier-row.twig
- templates/admin/package-row.twig

+## [1.2.9] - 2025-12-30
+
+### Fixed
+
+- **Price Header Not Translated**: The "Price (%s)" header in admin tables was not being properly translated because the translation function was placed incorrectly within the printf statement. Changed from `printf(__('Price (%s)', ...), ...)` to `printf(esc_html__('Price (%s)', 'wc-tier-package-prices'), ...)` to ensure proper translation while maintaining the currency placeholder functionality.
+
+- **Placeholder HTML Entity Encoding Issue**: Currency symbols in price input placeholders were being displayed as HTML entities (e.g., "€" instead of "€") because the concatenated string was being passed through the translation filter which was encoding special characters. Removed the unnecessary translation filter from concatenated placeholder strings since they are example values that should not be translated.
+
+- **Variation Pricing Still Not Deletable (Regression from v1.2.8)**: Despite the fix in v1.2.8, variation pricing data was still not being properly deleted in all scenarios. The issue was with the conditional logic structure - the code had separate `if/else` branches that could fail in edge cases. Restructured the save logic to be more defensive: initialize arrays at the start, populate only if valid POST data exists, then unconditionally perform either update (if not empty) or delete (if empty). This guarantees proper cleanup regardless of POST data structure.
+
+### Technical Details
+
+**Translation Fix**:
+
+- Changed all 6 instances of `printf(__('Price (%s)', 'wc-tier-package-prices'), ...)`
+- To: `printf(esc_html__('Price (%s)', 'wc-tier-package-prices'), ...)`
+- The `__()` function now receives the text domain parameter correctly
+- Added `esc_html` for proper output escaping
+
+**Placeholder Encoding Fix**:
+
+- Changed tier-row.twig placeholder from: `{{ ('e.g., 9.99 ' ~ currency_symbol)|__('wc-tier-package-prices') }}`
+- To: `{{ 'e.g., 9.99 ' ~ currency_symbol }}`
+- Changed package-row.twig placeholder from: `{{ ('e.g., 99.99 ' ~ currency_symbol)|__('wc-tier-package-prices') }}`
+- To: `{{ 'e.g., 99.99 ' ~ currency_symbol }}`
+- Removed translation filter from concatenated example values to prevent HTML entity encoding
+
+**Variation Save Logic Refactor**:
+
+```php
+// Old pattern (v1.2.8):
+if (isset($_POST['wc_tpp_tiers'][$loop])) {
+    $tiers = array();
+    // ... populate tiers ...
+    if (!empty($tiers)) {
+        update_post_meta(...);
+    } else {
+        delete_post_meta(...);
+    }
+} else {
+    delete_post_meta(...);
+}
+
+// New pattern (v1.2.9):
+$tiers = array();
+if (isset($_POST['wc_tpp_tiers'][$loop]) && is_array($_POST['wc_tpp_tiers'][$loop])) {
+    // ... populate tiers ...
+}
+// Always perform update or delete based on final state
+if (!empty($tiers)) {
+    update_post_meta(...);
+} else {
+    delete_post_meta(...);
+}
+```
+
+- Eliminated conditional branching that could miss edge cases
+- Added explicit `is_array()` check for extra safety
+- Guaranteed that one of update_post_meta() or delete_post_meta() is always called
+- Applied to both `save_variation_pricing_fields()` for tier and package pricing
+
+**User Impact**:
+
+- Price headers now display in the administrator's configured language
+- Currency symbols display correctly without HTML encoding in placeholders
+- Variation pricing deletion now works reliably in all scenarios
+- Database remains clean with no orphaned empty arrays
+
