 - 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: 745KB
+   - 642 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
+
+**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
