+### What's Changed
+
+* fix: resolve cache session handler index inconsistencies by @CodeWithKyrian in https://github.com/php-mcp/server/pull/36
+* feat: Add comprehensive callable handler support for closures, static methods, and invokable classes by @CodeWithKyrian in https://github.com/php-mcp/server/pull/38
+* feat: Enhanced Completion Providers with Values and Enum Support by @CodeWithKyrian in https://github.com/php-mcp/server/pull/40
+
+### Upgrade Guide
+
+If you're using the `CompletionProvider` attribute with the named `providerClass` parameter, consider updating to the new `provider` parameter for consistency:
+
+```php
+// Before (still works)
+#[CompletionProvider(providerClass: UserProvider::class)]
+
+// After (recommended)
+#[CompletionProvider(provider: UserProvider::class)]
+
+```
+The old `providerClass` parameter continues to work for backward compatibility, but may be dropped in a future major version release.
