This release adds two new filter functions in the tfplan-functions module to require a specific key of a specific map to have or not have specific values. See https://github.com/hashicorp/terraform-sentinel-policies/blob/main/common-functions/tfplan-functions/docs/filter_attribute_map_key_contains_items_in_list.md and https://github.com/hashicorp/terraform-sentinel-policies/blob/main/common-functions/tfplan-functions/docs/filter_attribute_map_key_contains_items_not_in_list.md.
A new policy, https://github.com/hashicorp/terraform-sentinel-policies/blob/main/aws/check-ec2-environment-tag.sentinel, uses the second of those functions.
It also adds a new gcp-functions module with a single function to find resources of various types with tags. See https://github.com/hashicorp/terraform-sentinel-policies/blob/main/gcp/gcp-functions/docs/find_resources_with_standard_tags.md.
The https://github.com/hashicorp/terraform-sentinel-policies/blob/main/gcp/enforce-mandatory-labels.sentinel policy has been revised to use the new function.
