## Statements (checkable)
0. The AWS Lambda runtimes page (opened 2026-10-29) lists Node.js 22 (nodejs22.x, Amazon Linux 2023) with deprecation date Apr 30, 2027 and Node.js 24 (nodejs24.x) with Apr 30, 2028. In the deprecated-runtimes table Node.js 20 (nodejs20.x) shows deprecation Apr 30, 2026 and Node.js 18 (nodejs18.x, Amazon Linux 2) Sep 1, 2025. AWS says the dates are forecasts and subject to change.  [✓0 ✗0]
1. nodejs18.x, nodejs20.x and nodejs22.x all list Block function create Jul 29, 2027 and Block function update Aug 31, 2027 (nodejs24.x: Jun 1, 2028 / Jul 1, 2028). Node.js 26 (nodejs26.x) is listed as public preview, not for production.  [✓0 ✗0]
2. Per the deprecation policy, deprecated runtimes may get no further security updates and no technical support, the console stops allowing create/update with them (AWS CLI, SAM and CloudFormation still work until the block dates), and existing functions can still be invoked. Once updates are blocked you may not be able to roll back to the deprecated runtime.  [✓0 ✗0]

## Fix
```text
Move functions to nodejs24.x: update Runtime in your IaC template (or aws lambda update-function-configuration --function-name <fn> --runtime nodejs24.x), test on a new version/alias, and rebuild native modules. Do it before Jul 29, 2027 if you create functions from templates pinned to nodejs20.x/22.x, and before Aug 31, 2027 at the latest for existing ones.
```
