+# Fix outdated jsonConfig schema URL in VSCode settings
+
+The VSCode settings for JSON Config schema validation have been updated to use the official schema location. If you have an existing adapter with VSCode configuration, you should update the schema URL for better IntelliSense and validation.
+
+## What changed
+
+The jsonConfig schema URL has been updated from the old location to the official source:
+
+**Old URL (deprecated):**
+```
+https://raw.githubusercontent.com/ioBroker/adapter-react-v5/main/schemas/jsonConfig.json
+```
+
+**New URL (official):**
+```
+https://raw.githubusercontent.com/ioBroker/ioBroker.admin/master/packages/jsonConfig/schemas/jsonConfig.json
+```
+
+## How to update your adapter
+
+Open `.vscode/settings.json` in your adapter directory and locate the `json.schemas` section. Update the jsonConfig schema URL:
+
+```diff
+{
+	"json.schemas": [
+		{
+			"fileMatch": ["io-package.json"],
+			"url": "https://json.schemastore.org/io-package"
+		},
+		{
+			"fileMatch": [
+				"admin/jsonConfig.json",
+				"admin/jsonCustom.json",
+				"admin/jsonTab.json"
+			],
+-			"url": "https://raw.githubusercontent.com/ioBroker/adapter-react-v5/main/schemas/jsonConfig.json"
++			"url": "https://raw.githubusercontent.com/ioBroker/ioBroker.admin/master/packages/jsonConfig/schemas/jsonConfig.json"
+		}
+	]
+}
+```
+
+## Benefits
+
+- Uses the official, actively maintained schema from ioBroker.admin
+- Ensures accurate validation and IntelliSense for JSON Config files
+- Future-proofs your development environment against schema changes

+# Remove Node.js 18 support from adapter creator
+
+Node.js 18 is approaching end-of-life and new adapters should target more recent Node.js versions. The adapter creator now only supports Node.js 20 and 22 as minimum version options.
+
+## What changed
+
+- **Removed Node.js 18** from the available minimum version choices
+- **Updated migration logic** to automatically upgrade existing projects using Node.js 18 to Node.js 20
+- **Updated TypeScript interfaces** to reflect the new supported versions (`"20" | "22"`)
+
+## Migration behavior
+
+When migrating existing adapters that currently use Node.js 18 (`@tsconfig/node18` dependency), the tool will automatically select **Node.js 20** as the target version instead. This ensures a smooth upgrade path for existing projects while preventing new adapters from being created with outdated Node.js versions.
+
+## Manual migration for existing adapters
+
+If you have an existing adapter currently targeting Node.js 18, you should manually upgrade to Node.js 20 or 22:
+
+### 1. Update package.json engines field
+
+```diff
+{
+  "engines": {
+-   "node": ">= 18"
++   "node": ">= 20"
+  }
+}
+```
+
+### 2. Update Node.js type definitions
+
+```bash
+npm i -D @types/node@20
+```
+
+### 3. Update TypeScript configuration base
+
+First, uninstall the old tsconfig base:
+```bash
+npm uninstall -D @tsconfig/node18
+```
+
+Then install the new one:
+```bash
+npm i -D @tsconfig/node20
+```
+
+### 4. Update tsconfig.json
+
+```diff
+{
+- "extends": "@tsconfig/node18/tsconfig.json",
++ "extends": "@tsconfig/node20/tsconfig.json",
+  // ...
+}
+```
+
+### 5. Update GitHub Actions workflow
+
+Edit `.github/workflows/test-and-release.yml`:
+
+```diff
+     steps:
+       - uses: ioBroker/testing-action-check@v1
+         with:
+-          node-version: '18.x'
++          node-version: '20.x'
+           lint: true
+
+     strategy:
+       matrix:
+-        node-version: [18.x, 20.x, 22.x]
++        node-version: [20.x, 22.x]
+         os: [ubuntu-latest, windows-latest, macos-latest]
+```
+
+## Benefits
+
+- **Better security**: Node.js 20+ includes important security improvements
+- **Enhanced performance**: Newer Node.js versions offer better performance
+- **Modern features**: Access to the latest JavaScript and Node.js features
+- **Long-term support**: Node.js 20 is an LTS version with extended support until 2026
