v6.0.0

BREAKING CHANGES:

• data-source/aws_ami: The severity of the diagnostic returned when most_recent is true and owner and image ID filter criteria has been increased to an error. Existing configurations which were previously receiving a warning diagnostic will now fail to apply. To prevent this error, set the owner argument or include a filter block with an image-id or owner-id name/value pair. To continue using unsafe filter values with most_recent set to true, set the new allow_unsafe_filter argument to true. This is not recommended. (#42114)
• data-source/aws_ecs_task_definition: Remove inference_accelerator attribute. Amazon Elastic Inference reached end of life on April, 2024. (#42137)
• data-source/aws_ecs_task_execution: Remove inference_accelerator_overrides attribute. Amazon Elastic Inference reached end of life on April, 2024. (#42137)
• data-source/aws_elbv2_listener_rule: The action.authenticate_cognito, action.authenticate_oidc, action.fixed_response, action.forward, action.forward.stickiness, action.redirect, condition.host_header, condition.http_header, condition.http_request_method, condition.path_pattern, condition.query_string, and condition.source_ip attributes are now list nested blocks instead of single nested blocks (#42283)
• data-source/aws_identitystore_user: filter has been removed (#42325)
• data-source/aws_launch_template: Remove elastic_inference_accelerator attribute. Amazon Elastic Inference reached end of life on April, 2024. (#42137)
