+* compute: added `provisioned_throughput` field to `google_compute_instance_template` resource ([#19852](https://github.com/hashicorp/terraform-provider-google/pull/19852))
+* compute: added `provisioned_throughput` field to `google_compute_region_instance_template` resource ([#19852](https://github.com/hashicorp/terraform-provider-google/pull/19852))
+* container: added support for additional values `KCP_CONNECTION`, and `KCP_SSHD`in `google_container_cluster.logging_config` ([#19812](https://github.com/hashicorp/terraform-provider-google/pull/19812))

+* networkconnectivity: added `linked_producer_vpc_network` field to `google_network_connectivity_spoke` resource ([#19806](https://github.com/hashicorp/terraform-provider-google/pull/19806))
+* secretmanager: added `is_secret_data_base64` field to `google_secret_manager_secret_version` and `google_secret_manager_secret_version_access` datasources ([#19831](https://github.com/hashicorp/terraform-provider-google/pull/19831))
+* secretmanager: added `is_secret_data_base64` field to `google_secret_manager_regional_secret_version` and `google_secret_manager_regional_secret_version_access` datasources ([#19831](https://github.com/hashicorp/terraform-provider-google/pull/19831))
+* spanner: added `kms_key_names` to `encryption_config` in `google_spanner_database` ([#19846](https://github.com/hashicorp/terraform-provider-google/pull/19846))

+BUG FIXES:
+* bigquery: fixed a regression that caused `google_bigquery_dataset_iam_*` resources to attempt to set deleted IAM members, thereby triggering an API error ([#19857](https://github.com/hashicorp/terraform-provider-google/pull/19857))
+* compute: fixed an issue in `google_compute_backend_service` and `google_compute_region_backend_service` to allow sending `false` for `iap.enabled` ([#19795](https://github.com/hashicorp/terraform-provider-google/pull/19795))
+* container: `node_config.linux_node_config`, `node_config.workload_metadata_config` and `node_config.kubelet_config` will now successfully send empty messages to the API when `terraform plan` indicates they are being removed, rather than null, which caused an error. The sole reliable case is `node_config.linux_node_config` when the block is removed, where there will still be a permadiff, but the update request that's triggered will no longer error and other changes displayed in the plan should go through. ([#19842](https://github.com/hashicorp/terraform-provider-google/pull/19842))
+* pubsub: fixed permadiff with configuring an empty `retry_policy` in `google_pubsub_subscription` ([#19784](https://github.com/hashicorp/terraform-provider-google/pull/19784))
