    and reference the security groups by their `id`.

  * Lists materialized using splat syntax, for example `aws_instance.foo.*.id` are now ordered by the count index rather than lexographically sorted. If this produces a large number of undesirable differences, you can use the new `sort()` interpolation function to produce the previous behaviour.
+ * AWS Kinesis Firehose has been refactored to support Redshift as a destination in addition to S3. As a result, the configuration has changed and users will need to update their configuration to match the new `s3_configuration` block. Checkout the documentaiton on [AWS Kinesis Firehose](http://localhost:4567/docs/providers/aws/r/kinesis_firehose_delivery_stream.html) for more information [GH-7375]
  * `aws_route53_record`: `latency_routing_policy`, `geolocation_routing_policy`, and `failover_routing_policy` block options have been added. With these additions we’ve renamed the `weight` attribute to `weighted_routing_policy`, and it has changed from a string to a block to match the others. Please see the updated documentation on using `weighted_routing_policy`:  https://www.terraform.io/docs/providers/aws/r/route53_record.html . [GH-6954]
  * You now access the values of maps using the syntax `var.map["key"]` or the `lookup` function instead of `var.map.key`.
  * Outputs on `terraform_remote_state` resources are now top level attributes rather than inside the `output` map. In order to access outputs, use the syntax: `terraform_remote_state.name.outputname`. Currently outputs cannot be named `config` or `backend`.
