Appwrite 1.4

]I have a doubt. I was using Appwrite in version 1.3 and updated to version 1.4. I would like to know if there have been changes to the structure or if I can use the functions from version 1.3 in version 1.4?

function 1.3

module.exports = async function (req, res) {

  const client = new Client()
  .setEndpoint(req.variables['APPWRITE_FUNCTION_ENDPOINT'])
  .setProject(req.variables['APPWRITE_FUNCTION_PROJECT_ID'])
  .setKey(req.variables['APPWRITE_FUNCTION_API_KEY'])
  .setSelfSigned(true);

  const databases = new  Databases(client); 

  const reqPayload = req.payload;
  const { id_order} = JSON.parse(reqPayload);
}```

Or do I really need to put it in this model below

function 1.4

module.exports = async function (context) { const client = new Client() .setEndpoint(process.env["APPWRITE_FUNCTION_ENDPOINT"]) .setProject(process.env["APPWRITE_FUNCTION_PROJECT_ID"]) .setKey(process.env["APPWRITE_FUNCTION_API_KEY"]) .setSelfSigned(true);

const databases = new Databases(client); const body = context.req.bodyRaw; ```

Appwrite 1.4 will keep executing function from 1.3, however there are many great changes in 1.4 that worth to upgrade your function syntax, you can check detailed information from here:

https://appwrite.io/docs/products/functions/development#upgrade

But could I run the 1.3 functions in 1.4.2 without changing the syntax? For example, could I continue to get environment variables in Appwrite 1.4 using req.variables? Or even getting the body that comes in the request using req.payload? Or would I actually need to change to process.env and req.body/bodyRaw

I didn't find anything about this in the documentation.

Yes, you could still run the 1.3 function without any change after upgrade
