Support for Java and PowerShell has been added to the existing public preview for Azure SQL bindings for Azure Functions, which now supports C#, JavaScript, Python, Java, and PowerShell.

Also going GA in the fall update is Azure Functions runtime 4.0, which supports these language/runtime versions: Node.js 14, 16 (preview) Python 3.7, 3.8, 3.9 Java 8, 11 PowerShell 7.0 Custom handlers ...

You can even use this technique to add any custom extensions you’ve written. Each function in your custom handler needs its own functions.json file in a folder with the same name as the function.

Microsoft announced several new features that are now generally available in the fall update of Azure Functions, used for event-driven serverless computing in the cloud.
