v2.37.0

NOTES:

• all: This Go module has been updated to Go 1.23 per the Go support policy. It is recommended to review the Go 1.23 release notes before upgrading. Any consumers building on earlier Go versions may experience errors. (#1445)
• all: This release contains new fields and structs for implmenting managed resource identity. Resource identity is data that is defined by a separate schema and is stored alongside resource state. Identity data is used by Terrform to uniquely identify a remote object and is meant to be immutable during the remote object's lifecycle. Resources that support identity can now be imported using the identity attribute in Terraform configuration import blocks, available in Terraform v1.12+. The resource.Identity field on the schema.Resource struct can be used to support identity by defining an identity schema. Once the identity schema is defined, you can read and store identity data in the state file with the new IdentityData struct that is available via the Identity() method on schema.ResourceData and schema.ResourceDiff structs. (#1444)

FEATURES:

• helper/schema: Added new TestResourceDataWithIdentityRaw function for creating a ResourceData struct with identity data for unit testing. (#1475)
• helper/schema: Added new Identity field to Resource that supports defining an identity schema for managed resources only. (#1444)
• Added new ImportStatePassthroughWithIdentity helper that can support both identity and ID importing via a single field. (#1474)

ENHANCEMENTS:

• helper/schema: Added RequiredForImport and OptionalForImport fields to the Schema struct, which are only valid for identity schemas. (#1444)
• helper/schema: Updated ResourceData to support passing of identity data in CRUD and import functions for managed resources. (#1444)

BUG FIXES:

• helper/schema: Fixed bug that blocked write-only attributes from being used with resources without update functions. (#1472)

v2.37.0-beta.1

NOTES:

• This beta pre-release continues the implementation of managed resource identity, which should now be used with Terraform v1.12.0-beta2. Managed resources now can support import by identity during plan and apply workflows. Managed resources that already support import via the schema.Resource.Importer field still need to set an ID during import when an identity is provided. The RequiredForImport and OptionalForImport fields on the identity schema can be used to control the validation that Terraform core will apply to the import config block. (#1463)

v2.37.0-alpha.1

NOTES:

• all: This Go module has been updated to Go 1.23 per the Go support policy. It is recommended to review the Go 1.23 release notes before upgrading. Any consumers building on earlier Go versions may experience errors. (#1445)
• This alpha pre-release contains an initial implementation for managed resource identity, which can used with Terraform v1.12.0-alpha20250319, to store and read identity data during plan and apply workflows. A managed resource identity can be used by defining an identity schema in the resource.Identity field. Once the identity schema is defined, you can read and store identity data in the new IdentityData struct that is available via the new Identity() method on ResourceData and ResourceDiff structs.
