+### 2026-02-03 - Version 0.7.0 (Contact Form 7 Integration)
+
+**Completed:**
+
+- Created `src/Integration/CF7.php` (~750 lines)
+  - Custom form tags: `[bnb_building_select]`, `[bnb_room_select]`, `[bnb_date_checkin]`, `[bnb_date_checkout]`, `[bnb_guests]`
+  - Server-side validation for all custom tags
+  - Availability validation in `wpcf7_before_send_mail` hook
+  - Automatic booking creation on form submission via `wpcf7_mail_sent`
+  - Guest record creation/linking using `find_or_create_guest()` pattern
+  - Custom mail tags: `[_bnb_room_name]`, `[_bnb_building_name]`, `[_bnb_calculated_price]`, `[_bnb_nights]`, `[_bnb_booking_reference]`
+  - Form type detection via CSS class `wp-bnb-booking-form`
+- Created `assets/js/cf7-integration.js` (~230 lines)
+  - Building-based room filtering (rooms dropdown updates when building selected)
+  - Date validation (check-out after check-in, no past dates)
+  - Guest capacity validation against room limits
+  - AJAX availability checking with status display
+  - AJAX price calculation with formatted display
+  - Debounced updates to prevent excessive requests
+- Created `assets/css/cf7-integration.css` (~200 lines)
+  - Two-column responsive form layout
+  - Availability status indicators (checking spinner, available checkmark, unavailable X)
+  - Price display formatting
+  - Capacity warning styling
+  - Dark mode support via `prefers-color-scheme`
+  - Print styles (hide interactive elements)
+- Updated `src/Plugin.php`
+  - Added `use Magdev\WpBnb\Integration\CF7` import
+  - CF7 initialization in `init_frontend()` when WPCF7 class exists
+  - CF7 assets enqueuing with localized i18n strings
+- Updated `README.md` with comprehensive CF7 documentation
+  - Custom form tags reference with options
+  - Example booking form template
+  - Example inquiry form template
+  - Custom mail tags documentation
+
+**Files Created:**
+
+- `src/Integration/CF7.php` - Main CF7 integration class
+- `assets/js/cf7-integration.js` - Frontend JavaScript
+- `assets/css/cf7-integration.css` - Form styling
+
+**Learnings:**
+
+- CF7 custom tags registered via `wpcf7_add_form_tag()` with callback functions
+- Validation filters follow pattern `wpcf7_validate_{tag_name}`
+- `wpcf7_before_send_mail` can abort submission by setting `$abort` to true and adding validation error
+- `wpcf7_mail_sent` fires after successful email, ideal for booking creation
+- Custom mail tags via `wpcf7_special_mail_tags` filter receive submission data
+- Form type detection by CSS class more reliable than checking for specific tags
+- Room dropdown with `data-building` attributes enables client-side filtering
+- AJAX endpoints reuse existing `wp_bnb_get_availability` and `wp_bnb_calculate_price` actions
+- CF7 assets should depend on `contact-form-7` script/style handles
+- Guest linking uses email as unique identifier for find-or-create pattern
+
+**Released:**
+
+- Committed: `28350aa` on dev branch
+- Merged to main (fast-forward)
+- Tagged: `v0.7.0`
+- Pushed to origin: dev, main, v0.7.0
