+## [1.4.1] - 2026-02-03
+
+### Added
+
+- **Localhost License Bypass**: License validation is automatically bypassed for localhost environments
+  - Supports localhost, 127.0.0.1, ::1 (IPv6), `*.localhost`, `*.local`, `*.test`, `*.example`, `*.invalid`
+  - Private IP ranges (Docker, VMs) are also recognized as localhost
+  - Displays "(Localhost environment - license validation bypassed)" in License Status
+
+- **Self-Licensing Bypass**: License validation is bypassed when the site URL matches the license server URL
+  - Useful for testing the plugin on the license server itself
+  - Displays "(Self-licensing server - license validation bypassed)" in License Status
+
+- **Auto-Update System**: Plugin can now receive updates directly from the license server
+  - New "Auto-Updates" settings tab under WooCommerce > Tier & Package Prices
+  - **Enable Update Notifications**: Toggle to check for available updates (default: enabled)
+  - **Automatically Install Updates**: Optional auto-install when WordPress performs background updates
+  - **Check Frequency**: Configurable hours between update checks (1-168 hours, default: 12)
+  - **Update Status**: Shows current version and available update with "Check for Updates" button
+  - Updates appear in WordPress Dashboard > Updates with full plugin info
+
+- **New Classes**:
+  - `WC_TPP_License_Checker`: Singleton class handling license validation with localhost/self-licensing bypass
+  - `WC_TPP_Update_Checker`: Singleton class integrating with WordPress plugin update system
+
+### Technical Details
+
+**License Checker Features**:
+
+- `is_localhost()`: Detects localhost environments using multiple patterns
+- `is_self_licensing()`: Compares license server URL with site URL
+- `is_license_valid()`: Main entry point with bypass logic
+- `get_bypass_reason()`: Returns 'localhost', 'self_licensing', or null
+- Cached validation (1 hour success, 5 minutes error)
+
+**Update Checker Features**:
+
+- Hooks into `pre_set_site_transient_update_plugins` for update detection
+- Hooks into `plugins_api` for update modal information
+- Hooks into `http_request_args` for license authentication
+- Hooks into `auto_update_plugin` for background updates
+- Can be disabled via `WC_TPP_DISABLE_AUTO_UPDATE` constant
+
+**New Settings Options**:
+
+- `wc_tpp_update_notification_enabled` (yes/no, default: yes)
+- `wc_tpp_auto_install_enabled` (yes/no, default: no)
+- `wc_tpp_update_check_frequency` (number, default: 12)
+
+**Update Server Endpoint**:
+
+- POST to `/wp-json/wc-licensed-product/v1/update-check`
+- Request body: `{license_key, domain, plugin_slug, current_version}`
+- Response: `{success, update_available, version, download_url, ...}`
+
+---
+
+## [1.4.0] - 2026-01-29
+
+### Added
+
+- **Gitea CI/CD Release Pipeline**: Automated release workflow triggered on version tags
+  - Validates plugin version matches tag version
+  - Installs production Composer dependencies
+  - Compiles translation files (.po to .mo)
+  - Creates release package with proper exclusions
+  - Generates SHA256 checksum
+  - Publishes release to Gitea with changelog notes
+
+---
+
+## [1.3.1] - 2026-01-27
+
+### Changed
+
+- **Switched to SecureLicenseClient**: Upgraded from basic `LicenseClient` to `SecureLicenseClient` with HMAC-SHA256 response signature verification for enhanced security against tampering and replay attacks
+
+- **Added Server Secret Configuration**: New "Server Secret" field in License settings for secure communication with the license server
+
+### Added
+
+- **Rate Limit Handling**: Added proper handling of `RateLimitExceededException` with user-friendly messages showing retry wait time
+- **Signature Verification Error Handling**: Added dedicated handling for `SignatureException` when response signatures fail verification
+- **URL Validation Error Handling**: Added handling for `InvalidArgumentException` from SSRF protection in the license client
+
+### Security
+
+- Response signatures are now verified using HMAC-SHA256 with license-specific derived keys (RFC 5869 HKDF)
+- The license client now validates server URLs to prevent SSRF attacks (blocks private IP ranges)
+- HTTP connections require HTTPS unless explicitly allowed for localhost testing
+
+### Technical Details
+
+**License Client Upgrade**:
+
+- Changed from `LicenseClient` to `SecureLicenseClient`
+- Added `serverSecret` parameter for signature verification
+- Library updated from `v0.1.0` to `dev-main` with new security features
+
+**New Exception Handling**:
+
+- `RateLimitExceededException` - shows retry time to user
+- `SignatureException` - indicates server secret mismatch
+- `InvalidArgumentException` - invalid/blocked URL detected
+
+**New Settings Field**:
+
+- `wc_tpp_license_server_secret` (password type) for the shared secret
+
+---
+
+## [1.3.0] - 2026-01-25
+
+### Breaking Changes
+
+- **PHP 8.3 Required**: Minimum PHP version increased from 7.4 to 8.3 to support modern dependencies and the license client library. Users on older PHP versions will see an admin notice and the plugin will not load.
+
+### Added
+
+- **License Management**: Integrated `magdev/wc-licensed-product-client` library for license validation and activation
+  - New "License" settings tab for entering license server URL and license key
+  - License validation and activation via AJAX with visual feedback
+  - License status display showing active/inactive state, expiration date, and last check time
+  - Cached license status with daily auto-refresh
+
+- **Settings Page Sub-tabs**: Split the settings page into "General" and "License" tabs using modern WooCommerce patterns
+  - Refactored to use `get_own_sections()` and `get_settings_for_{section}_section()` methods
+  - Improved navigation and organization of settings
+
+- **PHP Version Check**: Added runtime PHP version validation with admin notice for incompatible servers
+
+### Changed
+
+- Updated composer.json to require PHP 8.3+ and added `magdev/wc-licensed-product-client` dependency
+- Settings class now uses modern WooCommerce settings API patterns
+
+### Technical Details
+
+**New Dependencies**:
+- `magdev/wc-licensed-product-client: ^0.1` (from private repository)
+- `symfony/http-client: ^7.0` (transitive)
+- `psr/log: ^3.0`, `psr/cache: ^3.0`, `psr/http-client: ^1.0` (transitive)
+
+**License Client Integration**:
+- Uses `LicenseClient` class for API communication
+- AJAX endpoints: `wc_tpp_validate_license`, `wc_tpp_activate_license`
+- License status cached in WordPress transient (`wc_tpp_license_status`)

 ## Release Process

-### Version Bumping
+### Automated CI/CD Pipeline (Recommended)

-Update version in 3 places:
+Since v1.4.0, releases are automated via Gitea CI/CD. The pipeline is triggered when a version tag is pushed.

-1. `wc-tier-and-package-prices.php` - Plugin header comment (line 7)
-2. `wc-tier-and-package-prices.php` - `WC_TPP_VERSION` constant (line 26)
-3. `composer.json` - version field (optional, not critical)
-
-### Creating Release Package
-
-**CRITICAL:** The zip command must be run from the **parent directory** of the plugin folder to create proper archive structure.
+**Workflow:**

 ```bash
-# From parent directory (/home/magdev/workspaces/php)
-cd /home/magdev/workspaces/php
+# 1. Update version in 3 places
+#    - wc-tier-and-package-prices.php (header comment, line 7)
+#    - wc-tier-and-package-prices.php (WC_TPP_VERSION constant)

-
-**IMPORTANT NOTES:**
-
- The `vendor/` directory MUST be included in releases (Twig dependency required for runtime)
- Running zip from wrong directory creates empty or malformed archives
- Exclusion patterns must match the relative path structure used in zip command
- Always verify the package with `unzip -l` and test extraction before committing
-
-### Verification Steps
-
-After creating the release package, always verify:
-
-```bash
-# Check package size (should be ~400-450KB, NOT 8MB+ or near 0)
-ls -lh releases/wc-tier-and-package-prices-X.X.X.zip
-
-# Verify exclusions worked
-unzip -l releases/wc-tier-and-package-prices-X.X.X.zip | grep -E "CLAUDE\.md|\.claude/|\.git" && echo "ERROR: Excluded files found!" || echo "OK: No excluded files"
-
-# Test extraction
-cd /tmp && rm -rf test-extract && unzip -q /path/to/releases/wc-tier-and-package-prices-X.X.X.zip -d test-extract && ls -la test-extract/wc-tier-and-package-prices/
-
-# Verify version in extracted package
-head -30 /tmp/test-extract/wc-tier-and-package-prices/wc-tier-and-package-prices.php | grep -E "Version:|WC_TPP_VERSION"
-
-# Verify template changes (if applicable)
-grep 'class="regular"' /tmp/test-extract/wc-tier-and-package-prices/templates/admin/*.twig
-```
-
-### Git Workflow for Releases
-
-**Standard workflow:** Work on `dev` branch → merge to `main` → tag → push
-
-```bash
-# 1. Ensure you're on dev branch with all changes committed
-git checkout dev
-git add [files]
-git commit -m "Release version X.X.X - [description]
-
-🤖 Generated with [Claude Code](https://claude.com/claude-code)
-
-Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>"
-
-# 2. Merge dev to main
-git checkout main
-git merge dev --no-edit  # Should be fast-forward
-
-# 3. Create annotated tag
-git tag -a vX.X.X -m "Release version X.X.X - [description]"
-
-# 4. Push everything
-git push origin main
-git push origin vX.X.X
-
-# 5. Update dev and push
-git checkout dev
-git rebase main  # Should be up-to-date already
+Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>"
 git push origin dev

-# 6. If you have uncommitted local changes (like .claude/settings.local.json)
-git stash push -m "Local development settings"
-# ... do git operations ...
-git stash pop
+# 4. Merge to main and push
+git checkout main && git merge dev --no-edit && git push origin main
+
+# 5. Create and push tag (triggers CI/CD)
+git tag -a vX.X.X -m "Release version X.X.X - [description]"
+git push origin vX.X.X
+
+# 6. Switch back to dev
+git checkout dev
 ```

-**Important Git Notes:**
+**What the CI/CD Pipeline Does:**

- Always commit from `dev` branch first
- Tags should use format `vX.X.X` (e.g., `v1.1.22`)
- Use annotated tags (`-a`) not lightweight tags
- Commit messages should follow the established format with Claude Code attribution
- `.claude/settings.local.json` changes are typically local-only (stash before rebasing)
+1. Checks out code with git submodules (`submodules: recursive`)
+2. Sets up PHP 8.3 with required extensions
+3. Validates `composer.json`
+4. Installs production Composer dependencies (`--no-dev`)
+5. Compiles translation files (.po → .mo)
+6. Validates plugin version matches tag version
+7. Creates release package with proper exclusions
+8. Generates SHA256 checksum
+9. Verifies package structure
+10. Extracts changelog notes for release description
+11. Creates Gitea release with assets
+
+**Pipeline Location:** `.gitea/workflows/release.yml`
+
+**Required Secret:** `SRC_GITEA_TOKEN` - Gitea API token for creating releases
+
+### Git Submodule: wc-licensed-product-client
+
+The `magdev/wc-licensed-product-client` library is bundled as a git submodule in `lib/` to avoid private repository authentication during CI/CD and to prevent conflicts with Composer's `vendor/` directory.
+
+**Location:** `lib/wc-licensed-product-client/`
+
+**Submodule URL:** Relative path `../wc-licensed-product-client.git` (works with Gitea CI/CD)
+
+**Updating the submodule:**
+
+```bash
+# Update to a specific tag
+cd lib/wc-licensed-product-client
+git fetch --tags
+git checkout v0.2.3  # or desired version
+cd ../..
+git add lib/wc-licensed-product-client
+git commit -m "Update wc-licensed-product-client to v0.2.3"
+```
+
+**Composer Configuration:**
+
+```json
+{
+  "repositories": [
+    {
+      "type": "path",
+      "url": "lib/wc-licensed-product-client"
+    }
+  ],
+  "require": {
+    "magdev/wc-licensed-product-client": "^0.2"
+  }
+}
+```
+
+Composer creates a symlink in `vendor/magdev/wc-licensed-product-client` pointing to `lib/wc-licensed-product-client`.
+
+### Manual Release (Legacy)
+
+For manual releases without CI/CD, run from the **parent directory**:
+
+```bash
+cd /home/magdev/workspaces/php/wordpress/wp-content/plugins
+
+zip -r wc-tier-and-package-prices/releases/wc-tier-and-package-prices-X.X.X.zip wc-tier-and-package-prices/ \

 **Rule:** Always check `if (!empty($array))` before calling `update_post_meta()` for array data. If empty, call `delete_post_meta()` instead.

+#### CRITICAL: WordPress Translation Functions with printf (Learned in v1.2.9)
+
+When using `printf()` with WordPress translation functions, the text domain must be passed to the translation function, NOT to printf:
+
+**Wrong Pattern:**
+
+```php
+// ❌ WRONG - Text domain not passed to translation function
+printf(__('Price (%s)', 'wc-tier-package-prices'), get_woocommerce_currency_symbol());
+```
+
+**Problem:** The `__()` function receives the text domain as a second parameter, but in this pattern it's missing. This causes the string "Price (%s)" to not be found in translation files, so it won't be translated.
+
+**Correct Pattern:**
+
+```php
+// ✅ CORRECT - Text domain in translation function, with esc_html for output escaping
+printf(esc_html__('Price (%s)', 'wc-tier-package-prices'), get_woocommerce_currency_symbol());
+```
+
+**Why This Works:**
+
+- `esc_html__('Price (%s)', 'wc-tier-package-prices')` translates the string and returns it
+- `printf()` then substitutes the `%s` placeholder with the currency symbol
+- The translated string is used in the final output
+- `esc_html` ensures proper output escaping
+
+**Applied in v1.2.9:** All 6 table headers in `includes/class-wc-tpp-product-meta.php`
+
+#### CRITICAL: Twig Translation Filters and HTML Entity Encoding (Learned in v1.2.9)
+
+When concatenating dynamic values in Twig templates, applying the translation filter can cause HTML entity encoding issues:
+
+**Wrong Pattern:**
+
+```twig
+{# ❌ WRONG - Translation filter encodes special characters in concatenated string #}
+placeholder="{{ ('e.g., 9.99 ' ~ currency_symbol)|__('wc-tier-package-prices') }}"
+```
+
+**Problem:** When `currency_symbol` contains special characters (€, £, ¥, etc.), the concatenated string is passed through the translation function which treats it as a translatable string and encodes special characters as HTML entities (`&euro;`, `&pound;`, etc.).
+
+**Correct Pattern:**
+
+```twig
+{# ✅ CORRECT - No translation filter, just concatenation #}
+placeholder="{{ 'e.g., 9.99 ' ~ currency_symbol }}"
+```
+
+**Why This Works:**
+
+- Placeholder examples don't need translation - they're illustrative values
+- Direct concatenation preserves special characters
+- Currency symbol displays correctly (€ instead of &euro;)
+
+**Rule:** Only apply translation filters to static text that needs translation, not to concatenated strings with dynamic values that contain special characters.
+
+**Applied in v1.2.9:**
+
+- `templates/admin/tier-row.twig` - Price input placeholder
+- `templates/admin/package-row.twig` - Price input placeholder
+
+#### CRITICAL: Defensive Programming for POST Data Processing (Learned in v1.2.9)
+
+The v1.2.8 fix for variation pricing deletion had the right logic but used a branching structure that could miss edge cases. The v1.2.9 refactor demonstrates a more defensive pattern:
+
+**Less Defensive Pattern (v1.2.8):**
+
+```php
+// ❌ BRITTLE - Multiple branches, easy to miss edge cases
+if (isset($_POST['wc_tpp_tiers'][$loop])) {
+    $tiers = array();
+    foreach ($_POST['wc_tpp_tiers'][$loop] as $tier) {
+        // ... populate tiers ...
+    }
+    if (!empty($tiers)) {
+        update_post_meta($variation_id, '_wc_tpp_tiers', $tiers);
+    } else {
+        delete_post_meta($variation_id, '_wc_tpp_tiers');
+    }
+} else {
+    delete_post_meta($variation_id, '_wc_tpp_tiers');
+}
+```
+
+**Problem:** Two separate code paths to `delete_post_meta()`. If logic changes, easy to update one path but forget the other.
+
+**More Defensive Pattern (v1.2.9):**
+
+```php
+// ✅ DEFENSIVE - Single decision point, guaranteed cleanup
+$tiers = array();
+if (isset($_POST['wc_tpp_tiers'][$loop]) && is_array($_POST['wc_tpp_tiers'][$loop])) {
+    foreach ($_POST['wc_tpp_tiers'][$loop] as $tier) {
+        // ... populate tiers ...
+    }
+}
+// Always execute one of these based on final state
+if (!empty($tiers)) {
+    update_post_meta($variation_id, '_wc_tpp_tiers', $tiers);
+} else {
+    delete_post_meta($variation_id, '_wc_tpp_tiers');
+}
+```
+
+**Why This Is Better:**
+
+- Initialize array at the start (guaranteed initial state)
+- Single conditional for populating (with extra `is_array()` safety check)
+- Single decision point for save/delete (one place to maintain)
+- Impossible to have a code path that doesn't call either update or delete
+- Much easier to reason about and modify
+
+**Key Principles:**
+
+1. **Initialize variables early** - Establish known initial state
+2. **Minimize branching** - Fewer code paths = fewer bugs
+3. **Single decision point** - One place determines final action
+4. **Add safety checks** - Validate assumptions (`is_array()`)
+5. **Guaranteed execution** - Always perform one of update/delete, never neither
+
+**Applied in v1.2.9:**
+
+- `save_variation_pricing_fields()` - Both tier and package pricing logic refactored
+
+**Rule:** When processing user input to decide between update and delete, prefer the pattern: initialize → conditionally populate → unconditionally act based on final state.

+## Session History
+
+### v1.3.0 Release Session (2026-01-25)
+
+**Accomplished:**
+
+1. Fixed known bugs from CLAUDE.md:
+   - Removed all releases from git tracking (`git rm --cached -r releases/`)
+   - Deleted all MD5 checksum files, keeping only SHA256
+   - Updated `.gitignore` to exclude `/releases/`
+
+2. Implemented v1.3.0 features:
+   - Bumped PHP requirement from 7.4 to 8.3 (breaking change)
+   - Added PHP version check with admin notice for incompatible servers
+   - Added `magdev/wc-licensed-product-client` library integration
+   - Refactored settings page to use WooCommerce modern sub-tabs pattern (`get_own_sections()`)
+   - Created "General" and "License" sub-tabs
+   - Implemented license management with AJAX validation/activation
+   - Added license status caching via WordPress transients
+   - Added CSS styling for license status display
+
+3. Updated all translation files:
+   - Added 28 new translation strings for license management
+   - Updated .pot template and all 7 .po files
+   - Compiled all .mo files
+
+4. Created release package:
+   - Package size: 737KB (increased due to new dependencies)
+   - 642 files included (more due to license client library)
+   - SHA256 checksum generated
+
+**Key Learnings:**
+
+- WooCommerce settings sub-tabs use `get_own_sections()` and `get_settings_for_{section}_section()` pattern
+- License client library `magdev/wc-licensed-product-client` is from private Gitea repo - requires `repositories` config in composer.json
+- Package version was `^0.1` not `^1.0` - always check available versions before setting constraint
+- Release package size increased from ~430KB to ~737KB due to new Composer dependencies
+
+### v1.3.1 Release Session (2026-01-27)
+
+**Accomplished:**
+
+1. Reviewed server-implementation.md from license client library
+2. Upgraded from `LicenseClient` to `SecureLicenseClient`:
+   - Added "Server Secret" configuration field in License settings tab
+   - Updated `get_license_client()` to use `SecureLicenseClient` with HMAC-SHA256 signature verification
+   - Updated JavaScript to pass `server_secret` in AJAX requests
+
+3. Added comprehensive exception handling:
+   - `RateLimitExceededException` - Shows retry time to user
+   - `SignatureException` - Reports signature verification failures
+   - `InvalidArgumentException` - SSRF protection for private IP blocking
+
+4. Updated Composer dependencies:
+   - Changed `magdev/wc-licensed-product-client` from `^0.1` to `dev-main`
+   - Library includes new security features (SSRF protection, response signatures)
+
+5. Updated translations:
+   - Added 7 new translation strings for v1.3.1
+   - All 7 language files updated and compiled
+
+6. Created release package:
+   - Package size: 775KB (after proper exclusions)
+   - 650 files included
+   - SHA256 checksum generated
+
+7. Updated README.md:
+   - Documented license management feature
+   - Updated PHP requirement to 8.3
+   - Added v1.3.0 and v1.3.1 changelog entries
+
+8. Re-released v1.3.1:
+   - Fixed release package exclusions (vendor .git dirs were included)
+   - Added `.claude/settings.json` to .gitignore
+
+**Key Learnings:**
+
+- `SecureLicenseClient` requires `serverSecret` parameter for HMAC verification
+- The library's exception classes are in `Magdev\WcLicensedProductClient\Exception\` and `Magdev\WcLicensedProductClient\Security\` namespaces
+- `RateLimitExceededException` has a `retryAfter` property (int seconds)
+- Always check library documentation in `docs/server-implementation.md` for implementation requirements
+
+**Release Package Learnings (CRITICAL):**
+
+- Vendor directories installed via Composer (dev-main) contain their own `.git/` folders
+- Release exclusion patterns must include `'wc-tier-and-package-prices/vendor/*/.git/*'` and `'wc-tier-and-package-prices/vendor/*/CLAUDE.md'`
+- Run zip from `/home/magdev/workspaces/php/wordpress/wp-content/plugins/` (NOT `/home/magdev/workspaces/php/`)
+- Always verify exclusions with: `unzip -l package.zip | grep -E "\.git/|CLAUDE\.md"`
+
+### v1.4.0 Release Session (2026-01-29)
+
+**Accomplished:**
+
+1. Created Gitea CI/CD release pipeline:
+   - `.gitea/workflows/release.yml` - Automated release workflow
+   - Triggers on version tags (`v*`)
+   - Validates plugin version matches tag
+   - Installs production Composer dependencies
+   - Compiles translations (.po → .mo)
+   - Creates release package with proper exclusions
+   - Generates SHA256 checksum
+   - Publishes release to Gitea with changelog notes
+
+2. Added git submodule for license client:
+   - Initially placed in `vendor/magdev/` - **FAILED** (Composer conflicts)
+   - Fixed: Moved to `lib/wc-licensed-product-client/` like wp-fedistream
+   - Uses relative URL `../wc-licensed-product-client.git`
+   - Pinned to v0.2.2 tag
+   - Avoids private repository authentication during CI/CD
+
+3. Updated documentation:
+   - README.md - Added CI/CD section, updated file structure
+   - CLAUDE.md - Updated release process, added submodule docs
+
+**Key Learnings:**
+
+- **CRITICAL:** Git submodules should be in `lib/` NOT `vendor/` to avoid Composer conflicts
+- Composer manages `vendor/` directory - don't put submodules there
+- Use relative submodule URL (`../repo.git`) for Gitea CI/CD compatibility
+- Use version constraint `^0.2` instead of `@dev` for stability
+- Git submodules require `submodules: recursive` in checkout action
+- Composer creates symlink from `vendor/` to `lib/` automatically
+
+**CI/CD Pipeline Notes:**
+
+- Pipeline file: `.gitea/workflows/release.yml`
+- Required secret: `SRC_GITEA_TOKEN` for Gitea API access
+- Uses `shivammathur/setup-php@v2` for PHP setup
+- Uses `actions/checkout@v4` with `submodules: recursive`
+- Modeled after working wp-fedistream implementation
+
+### v1.4.1 Release Session (2026-02-03)
+
+**Accomplished:**
+
+1. Implemented localhost license bypass:
+   - Created `WC_TPP_License_Checker` class (singleton pattern)
+   - `is_localhost()` detects localhost environments: localhost, 127.0.0.1, ::1, `*.localhost`, `*.local`, `*.test`, `*.example`, `*.invalid`, and private IP ranges
+   - `is_self_licensing()` compares license server URL with site URL
+   - `is_license_valid()` returns true for localhost/self-licensing without server check
+   - Updated license status display to show bypass reason
+
+2. Implemented auto-update system:
+   - Created `WC_TPP_Update_Checker` class (singleton pattern)
+   - Hooks into WordPress plugin update system (`pre_set_site_transient_update_plugins`, `plugins_api`, `http_request_args`, `auto_update_plugin`)
+   - Fetches update info from license server API endpoint
+   - Supports auto-install when WordPress performs background updates
+   - Configurable check frequency (1-168 hours)
+
+3. Added Auto-Updates settings tab:
+   - Enable Update Notifications (checkbox, default: yes)
+   - Automatically Install Updates (checkbox, default: no, requires valid license)
+   - Check Frequency in Hours (number, default: 12)
+   - Update Status display with "Check for Updates" button
+   - AJAX handler for manual update checks
+
+4. Updated all translation files:
+   - Added 23 new translation strings for v1.4.1
+   - All 7 language variants updated (de_DE, de_DE_informal, de_CH, de_CH_informal, fr_CH, it_CH, en_US)
+   - Compiled all .mo files
+
+**Key Implementation Details:**
+
+- License checker uses 1-hour cache for successful validation, 5-minute cache for errors
+- Update checker respects `WC_TPP_DISABLE_AUTO_UPDATE` constant to disable updates
+- Update server endpoint: `POST /wp-json/wc-licensed-product/v1/update-check`
+- Both new classes are instantiated in main plugin's `includes()` method
+- Auto-install requires valid license (disabled when no license active)
+
+**New Files:**
+
+- `includes/class-wc-tpp-license-checker.php`
+- `includes/class-wc-tpp-update-checker.php`
+
+**Modified Files:**
+
+- `wc-tier-and-package-prices.php` - Version bump, include new classes
+- `includes/class-wc-tpp-settings.php` - Added Auto-Updates tab, updated license status display
+- All translation files (.pot, .po, .mo)
+- `CHANGELOG.md` - v1.4.1 release notes
+- `CLAUDE.md` - Updated version and session history

+### Automated Releases
+
+This project uses a Gitea CI/CD pipeline for automated releases. When a version tag (e.g., `v1.4.0`) is pushed:
+
+1. Code is checked out with git submodules (dependencies bundled)
+2. The pipeline validates the plugin version matches the tag
+3. Composer dependencies are installed (production only)
+4. Translation files are compiled (.po → .mo)
+5. A release package is created with proper exclusions
+6. SHA256 checksum is generated
+7. Release is published to Gitea with changelog notes extracted from CHANGELOG.md
+
+The `magdev/wc-licensed-product-client` library is bundled as a git submodule to avoid private repository authentication during CI/CD.

magdev	63c8137f4e	Document v1.2.9 learnings in CLAUDE.md Added three new critical sections documenting lessons learned during v1.2.9 development: 1. WordPress Translation Functions with printf - Correct pattern: printf(esc_html__('Text (%s)', 'domain'), value) - Wrong pattern: printf(__('Text (%s)', 'domain'), value) - missing text domain - Explains why text domain must be in translation function - Shows proper output escaping with esc_html 2. Twig Translation Filters and HTML Entity Encoding - Explains why translation filters encode special characters in concatenated strings - Correct pattern: {{ 'text ' ~ currency_symbol }} (no translation filter) - Wrong pattern: {{ ('text ' ~ currency_symbol)\|__() }} causes HTML entity encoding - Rule: Only translate static text, not concatenated dynamic values 3. Defensive Programming for POST Data Processing - Compares v1.2.8 (branching) vs v1.2.9 (defensive) patterns - Shows why single decision point is better than multiple branches - Key principles: initialize early, minimize branching, guaranteed execution - Pattern: initialize → conditionally populate → unconditionally act Also corrected v1.2.8 examples that had wrong patterns, noting they were fixed in v1.2.9. These patterns prevent future bugs and ensure consistent, secure implementation. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>	2025-12-30 05:08:09 +01:00
