[Announcement] Exit Code for sam deploy —on-failure DELETE - SAM CLI

There is currently a bug with sam deploy when the flag `—on-failure DELETE` is provided, the exit code is 0, regardless of the stack actually being deployed. With the recent change https://github.com/aws/aws-sam-cli/pull/6258, sam deploy will now properly return an appropriate non-zero exit code when deploy fails. This will be implemented in the next release of AWS-SAM-CLI. Please be aware that the change may cause existing code that depends on the exit code of `sam deploy —on-failure DELETE` to fail, requiring updates.

## Does this affect me?
