Lambda Deploy automatically creates a new version and no option to disable that

[surjithctly]

Problem

When deploying modified Lambda code, it automatically creates a new version in the console and there is no option to disable that feature. I want the deploy to change $latest only. not create new version each time.

Steps to reproduce the issue

1. download a lambda fn
2. make some changes
3. click deploy on the auto-prompted dialog
4. visit aws lambda functions -> versions
5. you can see a new version is created

Expected behavior

1. it should not create new version until I manually specified
2. should only make changes to $latest only.

Can you provide more information about the Lambda function? do you have the function in a template? Is the quick edit and quick deploy?

I can confirm that this is creating new versions each time. This is because the Publish flag is set on each iteration of UpdateFunctionCode:

Let me confirm if this is intentional or not.

@vicheey this is just a normal lambda function, no templates. I opened in a workspace and made the edit and clicked deploy on the auto-popup which appeared.
