 * config: Terraform was not previously evaluating preconditions and postconditions during the apply phase for resource instances that didn't have any changes pending, which was incorrect because the outcome of a condition can potentially be affected by changes to _other_ objects in the configuration. Terraform will now always check the conditions for every resource instance included in a plan during the apply phase, even for resource instances that have "no-op" changes. This means that some failures that would previously have been detected only by a subsequent run will now be detected during the same run that caused them, thereby giving the feedback at the appropriate time. [GH-31491]
 * `terraform show -json`: Fixed missing unknown markers in the encoding of partially unknown tuples and sets. ([#31236](https://github.com/hashicorp/terraform/issues/31236))
 * `terraform output` CLI help documentation is now more consistent with web-based documentation. ([#29354](https://github.com/hashicorp/terraform/issues/29354))
+* getproviders: account for occasionally missing Host header in errors ([#31542](https://github.com/hashicorp/terraform/issues/31542))
