+* [@macbookandrew](https://github.com/macbookandrew) made their first contribution in https://github.com/laravel/mcp/pull/83

+
+### Breaking Change
+
+#### 1. Case Name Updates (https://github.com/laravel/mcp/pull/116)
+
+Applications referencing the previous case names will need manual updates.
+
+**Required changes**
+
+* `Role::ASSISTANT` should be updated to `Role::Assistant`
+* `Role::USER` should be updated to `Role::User`
+
+Make sure your codebase reflects these changes before upgrading to avoid build or runtime errors.
+
+#### 2. JsonSchema Contract Change (https://github.com/laravel/mcp/pull/120)
+
+Tool implementations that explicitly type hint `Illuminate\JsonSchema\JsonSchema` in their `schema()` or `outputSchema()` methods must update to use the contract interface `Illuminate\Contracts\JsonSchema\JsonSchema`.
+
+##### Migration Guide
+
+**Before**
+
+```php
+use Illuminate\JsonSchema\JsonSchema;
+
+public function schema(JsonSchema $schema): array
+{
+    //
+}
+
+
+```
+**After**
+
+```php
+use Illuminate\Contracts\JsonSchema\JsonSchema;
+
+public function schema(JsonSchema $schema): array
+{
+    //
+}
+
+
+```
+This affects only custom tool classes that override the schema methods. The update is minimal, requiring only the import change to the contract interface.
