Has App Service Environment Variable validation changed?

Hello,

We are currently running 4 environments with 8 web apps and 8 app service plans. The environment variables we are using were configured over a year ago and have been working without issue until now. One of the app services was cloned a week ago without issue.

However, as of yesterday (5/23/2024) attempting to clone the app service of a different environment is now giving validation errors for the environment variables

App setting names can only contain letters, numbers (0-9), periods ("."), and underscores ("_")

Is this a new change?

When did it go into effect?

And is it going to begin causing validation issues with our currently running apps that have environment variables like this for example

org:environment_variable=false
Azure App Service
Azure App Service
Azure App Service is a service used to create and deploy scalable, mission-critical web apps.
