+## [1.1.10] - 2025-12-31
+
+### Fixed
+
+- **CRITICAL**: Admin panel - Both General and Composable tabs visible simultaneously on initial page load
+- **CRITICAL**: Frontend - No products showing in product selector, only cart button and pricing visible
+- Empty product grid now shows helpful message instead of blank space
+
+### Changed
+
+- Added explicit `display: none` to `#composable_product_data` panel for proper initial hiding
+- Panel now only shows when `body.product-type-composable` class is present
+- Added empty state message in product selector template when no products are configured
+- Cleared Twig cache to ensure template changes take effect
+
+### Added
+
+- Empty state message: "No products available for selection. Please configure the product criteria in the admin panel."
+- Translations for empty state message in all 6 supported locales (de_DE, de_DE_informal, de_CH, de_CH_informal, fr_CH, it_CH)
+- Recompiled .mo translation files
+
+### Technical
+
+- Modified files: assets/css/admin.css (lines 7-16), templates/product-selector.twig (lines 12-15)
+- Root cause (admin): Panel lacked explicit CSS hiding rule, relied only on `hidden` class
+- Root cause (frontend): No feedback when products array is empty
+- Solution: CSS specificity + empty state conditional in Twig template
+
+### Notes
+
+- This release fixes two critical bugs discovered immediately after v1.1.9
+- Admin interface now correctly hides composable panel until product type is selected
+- Frontend provides clear user feedback when product selection is unavailable
+- All translation files now 100% complete (57/57 strings)
+
