1.13.0 (October 31, 2024)

NOTES:

Ephemeral resource support is in technical preview and offered without compatibility promises until Terraform 1.10 is generally available. (#1050)

FEATURES:

ephemeral: New package for implementing ephemeral resources (#1050)
ephemeral/schema: New package for implementing ephemeral resource schemas (#1050)

ENHANCEMENTS:

provider: Added ProviderWithEphemeralResources interface for implementing ephemeral resources (#1050)

provider: Added EphemeralResourceData to ConfigureResponse, to pass provider-defined data to ephemeral.EphemeralResource implementations (#1050)

1.12.0 (September 18, 2024)

NOTES:

all: This Go module has been updated to Go 1.22 per the Go support policy. It is recommended to review the Go 1.22 release notes before upgrading. Any consumers building on earlier Go versions may experience errors (#1033)

BUG FIXES:

providerserver: Fixed bug that prevented moved operation support between resource types for framework-only providers. (#1039)

1.11.0 (August 06, 2024)

NOTES:

Framework reflection logic (Config.Get, Plan.Get, etc.) for structs with tfsdk field tags has been updated to support embedded structs that promote exported fields. For existing structs that embed unexported structs with exported fields, a tfsdk ignore tag (tfsdk:"-") can be added to ignore all promoted fields.

For example, the following struct will now return an error diagnostic:

type thingResourceModel struct {
	Attr1 types.String `tfsdk:"attr_1"`
	Attr2 types.Bool   `tfsdk:"attr_2"`

	// Previously, this embedded struct was ignored, will now promote underlying fields
	embeddedModel
}

type embeddedModel struct {
	// No `tfsdk` tag
	ExportedField string
}

To preserve the original behavior, a tfsdk ignore tag can be added to ignore the entire embedded struct:

type thingResourceModel struct {
	Attr1 types.String `tfsdk:"attr_1"`
	Attr2 types.Bool   `tfsdk:"attr_2"`

	// This embedded struct will now be ignored
	embeddedModel      `tfsdk:"-"`
}

type embeddedModel struct {
	ExportedField string
}

(#1021)

ENHANCEMENTS:

all: Added embedded struct support for object to struct conversions with tfsdk tags (#1021)

1.6.0 (February 28, 2024)

BREAKING CHANGES:

function: Changed the framework type for variadic parameters to types.TupleType, where each element is the same element type. Provider-defined functions using a types.List for retrieving variadic argument data will need to update their code to use types.Tuple. (#923)
function: Altered the RunResponse type, replacing Diagnostics with FuncError (#925)
diag: Removed DiagnosticWithFunctionArgument interface. Removed NewArgumentErrorDiagnostic(), NewArgumentWarningDiagnostic() and WithFunctionArgument() functions. Removed AddArgumentError() and AddArgumentWarning() methods from Diagnostics. (#925)

FEATURES:

1.4.0 (September 06, 2023)

NOTES:

all: This Go module has been updated to Go 1.20 per the Go support policy. It is recommended to review the Go 1.20 release notes before upgrading. Any consumers building on earlier Go versions may experience errors. (#835)

FEATURES:

providerserver: Upgrade to protocol versions 5.4 and 6.4, which can significantly reduce memory usage with Terraform 1.6 and later when a configuration includes multiple instances of the same provider (#828)

resource/schema: Raise validation errors if attempting to use top-level for_each attribute name, which requires special Terraform configuration syntax to be usable by the resource (#704)
datasource/schema: Raise validation errors if attempting to use attribute names with leading numerics (0-9), which are invalid in the Terraform configuration language (#705)
provider/schema: Raise validation errors if attempting to use attribute names with leading numerics (0-9), which are invalid in the Terraform configuration language (#705)
resource/schema: Raise validation errors if attempting to use attribute names with leading numerics (0-9), which are invalid in the Terraform configuration language (#705)

1.2.0 (March 21, 2023)

NOTES:

New DEBUG level Detected value change between proposed new state and prior state log messages with the offending attribute path are now emitted when proposed new state value differences would cause the framework to automatically mark all unconfigured Computed attributes as unknown during planning. These can be used to troubleshoot potential resource implementation issues, or framework and Terraform plan logic bugs. (#630)
This Go module has been updated to Go 1.19 per the Go support policy. Any consumers building on earlier Go versions may experience errors. (#682)

FEATURES:

resource/schema: Introduce packages, interface types, and built-in static value functionality for schema-based default values (#674)

ENHANCEMENTS:

internal/fwserver: Added DEBUG logging to aid troubleshooting unexpected plans with unknown values (#630)

1.1.1 (January 13, 2022)

BUG FIXES:

all: Prevented tftypes.NewValue can't use []tftypes.Value as a tftypes.Object panics with schemas that included SingleNestedBlock (#624)

1.1.0 (January 13, 2022)

NOTES:

all: For data handling consistency with attributes, unconfigured list and set blocks will now be represented as a null list or set instead of a known list or set with zero elements. This prevents confusing situations with validation and plan modification, where it was previously required to check block values for the number of elements. Logic that was previously missing null value checks for blocks may require updates. (#604)
tfsdk: The Config, Plan, and State type PathMatches() method logic previously returned Invalid Path Expression for Schema Data errors based on implementation details of the underlying data, which prevented returning zero matches in cases where the expression is valid for the schema, but there was no actual data at the path. Providers can now determine whether zero matches is consequential for their use case. (#602)

ENHANCEMENTS:

path: Added Expressions type Matches method for checking if any expression in the collection matches a given path (#604)
tfsdk: Automatically prevented Terraform nested blocks must be empty to indicate no blocks errors for responses containing Plan and State types (#621)

types/basetypes: Fixed ObjectType type ApplyTerraform5AttributePathStep method to return an error instead of nil for invalid attribute name steps (#602)

1.0.1 (December 19, 2022)

BUG FIXES:

resource/schema/planmodifier: Prevented assignment to entry in nil map panic for Object type plan modifiers (#591)
types/basetypes: Prevented type mutation via the ObjectType type AttributeTypes() method return (#591)
types/basetypes: Prevented value mutation via the ListValue, MapValue, and SetValue type Elements() method return (#591)
types/basetypes: Prevented value mutation via the ObjectValue type AttributeTypes() and Attributes() method returns (#591)

1.0.0 (December 13, 2022)

NOTES:

tfsdk: The previously deprecated Schema type AttributeType() method has been removed. Use the Type() method instead. (#450)
tfsdk: The previously deprecated Schema type AttributeTypeAtPath() method has been removed. Use the TypeAtPath() or TypeAtTerraformPath() method instead. (#450)

0.11.0 (August 11, 2022)

NOTES:

This Go module has been updated to Go 1.18 per the Go support policy. Any consumers building on earlier Go versions may experience errors. (#445)
tfsdk: The Schema type AttributeAtPath() method signature will be updated from a *tftypes.AttributePath parameter to path.Path in the next release. Switch to the AttributeAtTerraformPath() method if *tftypes.AttributePath handling is still necessary. (#440)
tfsdk: The Schema type AttributeType() method has been deprecated in preference of the Type() method. (#440)
tfsdk: The Schema type AttributeTypeAtPath() method has been deprecated for the TypeAtPath() and TypeAtTerraformPath() methods. (#440)

tfsdk: Go types relating to provider handling have been migrated to the new provider package. Consult the pull request description for a full listing of find-and-replace information. (#432)
tfsdk: Go types relating to resource handling have been migrated to the new resource package. Consult the pull request description for a full listing of find-and-replace information. (#432)
tfsdk: The RequiresReplace(), RequiresReplaceIf(), and UseStateForUnknown() plan modifier functions, which only apply to managed resources, have been moved to the resource package. (#434)
tfsdk: The ResourceImportStatePassthroughID() function has been moved to resource.ImportStatePassthroughID(). (#432)
tfsdk: The Schema type AttributeAtPath method now returns a fwschema.Attribute interface instead of a tfsdk.Attribute type. Consumers will need to update from direct field usage to similarly named interface method calls. (#438)

FEATURES:

datasource: New package, which colocates all data source implementation types from the tfsdk package (#432)
provider: New package, which colocates all provider implementation types from the tfsdk package (#432)

tfsdk: The ModifyAttributePlanRequest, ModifyResourcePlanResponse, and ValidateAttributeRequest type AttributePath *tftypes.AttributePath fields are replaced with AttributePath path.Path (#390)
tfsdk: The PlanResourceChange RPC on destroy is now enabled. To prevent unexpected Terraform errors, the framework attempts to catch errant provider logic in plan modifiers when destroying. Resource level plan modifiers may require updates to handle a completely null proposed new state (plan) and ensure it remains completely null on resource destruction. (#409)
tfsdk: The ProviderConfigValidator interface Validate method is now ValidateProvider to support generic validators that satisfy DataSourceConfigValidator, ProviderConfigValidator, and ResourceConfigValidator (#405)
tfsdk: The RequiresReplaceIf and ResourceImportStatePassthroughID function *tftypes.AttributePath parameters are replaced with path.Path (#390)
tfsdk: The ResourceConfigValidator interface Validate method is now ValidateResource to support generic validators that satisfy DataSourceConfigValidator, ProviderConfigValidator, and ResourceConfigValidator (#405)

types: Method IsNull() for Number type will now return true if the struct is zero-value initialized. (#384)

0.9.0 (June 15, 2022)

BREAKING CHANGES:

attr: The Value interface now includes the IsNull() and IsUnknown() methods (#335)
attr: The Value interface now includes the String() method (#376)
tfsdk: ListNestedAttributes, SetNestedAttributes and MapNestedAttributes functions lost the second argument opts, as it was unused. (#349)

FEATURES:

providerserver: Implemented native protocol version 5 support (#368)

ENHANCEMENTS:

providerserver: Added NewProtocol5() and NewProtocol5WithError() functions, which return a protocol version 5 compatible provider server (#368)
providerserver: Added ServeOpts type ProtocolVersion field, which can be set to 5 or 6 and defaults to 6 (#368)
tfsdk: New function ValueFrom that takes a Go value and populates a compatible attr.Value, given a descriptive attr.Type. (#350)
tfsdk: Removed ListNestedAttributesOptions, SetNestedAttributesOptions and MapNestedAttributesOptions types, as they were empty (no fields) and unused. (#349)

types: Prevented potential loss of number precision with Int64 between 54 and 64 bits (#325)

0.8.0 (May 6, 2022)

BREAKING CHANGES:

diag: Removed Diagnostics type ToTfprotov6Diagnostics() method. This was not intended for usage by provider developers. (#313)
tfsdk: The ModifySchemaPlanRequest, ModifySchemaPlanResponse, ValidateSchemaRequest, and ValidateSchemaResponse types have been removed. These were not intended for provider developer usage. (#310)
tfsdk: The NewProtocol6Server() function, Serve() function, and ServeOpts type have been removed. Use the providerserver package instead. (#310)
tfsdk: The ResourceImportStateNotImplemented() function has been removed. Remove the Resource type ImportState method instead for resources that should not support import. (#312)

ENHANCEMENTS:

tfsdk: Propagated tf_data_source_type, tf_req_id, tf_resource_type, and tf_rpc fields in log entries (#315)

BUG FIXES:

all: Prevented This log was generated by an SDK subsystem logger that wasn't created before being used. warning messages in logging (#314)
tfsdk: Prevented Unable to create logging subsystem with AdditionalLocationOffset due to missing root logger options warning logs during acceptance testing (#315)

0.7.0 (April 28, 2022)

NOTES:

tfsdk: Providers may now optionally remove RemoveResource() calls from Resource type Delete methods (#301)
tfsdk: The NewProtocol6Server() function has been deprecated in preference of providerserver.NewProtocol6() and providerserver.NewProtocol6WithError() functions, which will simplify muxing and testing implementations. The tfsdk.NewProtocol6Server() function will be removed in the next minor version. (#308)
tfsdk: The ResourceImportStateNotImplemented() function has been deprecated. Instead, the ImportState method can be removed from the Resource and the framework will automatically return an error diagnostic if import is attempted. (#297)
tfsdk: The Resource interface no longer requires the ImportState method. A separate ResourceWithImportState interface now defines the same ImportState method. (#297)
tfsdk: The Serve() function has been deprecated in preference of the providerserver.Serve() function. The tfsdk.Serve() function will be removed in the next minor version. (#308)
tfsdk: The ServeOpts type has been deprecated in preference of the providerserver.ServeOpts type. When migrating, the Name field has been replaced with Address. The tfsdk.ServeOpts type will be removed in the next minor version. (#308)
tfsdk: The previously unexported server type has been temporarily exported to aid in the migration to the new providerserver package. It is not intended for provider developer usage and will be moved into an internal package in the next minor version. (#308)

FEATURES:

Introduced providerserver package, which contains all functions and types necessary for serving a provider in production or acceptance testing. (#308)
tfsdk: Added optional ResourceWithUpgradeState interface, which allows for provider defined logic when the UpgradeResourceState RPC is called (#292)

ENHANCEMENTS:

tfsdk: Added DEBUG level logging for all framework handoffs to provider defined logic (#300)
tfsdk: Added ResourceWithImportState interface, which allows Resource implementations to optionally define the ImportState method. (#297)
tfsdk: Added automatic (DeleteResourceResponse.State).RemoveResource() call after Resource type Delete method execution if there are no errors (#301)

0.6.1 (March 29, 2022)

BUG FIXES:

types: Prevented panics with missing type information during Float64, Int64, and Set validation logic (#259)

0.6.0 (March 10, 2022)

NOTES:

The underlying terraform-plugin-log dependency has been updated to v0.3.0, which includes a breaking change in the optional additional fields parameter of logging function calls to ensure correctness and catch coding errors during compilation. Any early adopter provider logging which calls those functions may require updates. (#268)

BREAKING CHANGES:

The ToTerraformValue method of the attr.Value interface now returns a tftypes.Value, instead of an interface{}. Existing types need to be updated to call tftypes.ValidateValue and tftypes.NewValue, passing the value they were returning before, instead of returning the value directly. (#231)
tfsdk: The ListNestedAttributesOptions, MapNestedAttributeOptions, and SetNestedAttributeOptions type MaxItems and MinItems fields have been removed since the protocol and framework never supported this type of nested attribute validation. Use attribute validators instead. (#249)

ENHANCEMENTS:

Added the ability to get an attribute as a generic attr.Value when using GetAttribute. (#232)
Logging can now be used by calling tflog.Trace, tflog.Debug, tflog.Info, tflog.Warn, or tflog.Error. See the tflog docs for more information. (#234)
tfsdk: Added Debug field to ServeOpts for running providers via debugger and testing processes (#243)

BUG FIXES:

tfsdk: Removed Schema restriction that it must contain at least one attribute or block (#252)
tfsdk: Support protocol version 5 and verify valid resource type in UpgradeResourceState RPC (#263)

0.5.0 (November 30, 2021)

BREAKING CHANGES:

Fixed RequiresReplace and RequiresReplaceIf to be more judicious about when they require a resource to be destroyed and recreated. They will no longer require resources to be recreated when any attribute changes, instead limiting it only to the attribute they're declared on. They will also not require resources to be recreated when they're being created or deleted. Finally, they won't require a resource to be recreated if the user has no value in the config for the attribute and the attribute is computed; this is to prevent the resource from being destroyed and recreated when the provider changes the value without any user prompting. Providers that wish to destroy and recreate the resource when an optional and computed attribute is removed from the user's config should do so in their own plan modifier. (#213)
RequiresReplaceIf no longer overrides previous plan modifiers' value for RequiresReplace if the function returns false. (#213)
diag: The AttributeErrorDiagnostic and AttributeWarningDiagnostic types have been removed. Any usage can be replaced with DiagnosticWithPath. (#219)
tfsdk: The AddAttributeError, AddAttributeWarning, AddError, and AddWarning methods on the ConfigureProviderResponse, CreateResourceResponse, DeleteResourceResponse, ModifyAttributePlanResponse, ModifyResourcePlanResponse, ReadDataSourceResponse, ReadResourceResponse, and UpdateResourceResponse types have been removed in preference of the same methods on the Diagnostics field of these types. For example, code such as resp.AddError("...", "...") can be updated to resp.Diagnostics.AddError("...", "..."). (#198)
tfsdk: The Config, Plan, and State type GetAttribute methods now return diagnostics only and require the target as the last parameter, similar to the Get method. (#167)

FEATURES:

Added tfsdk.UseStateForUnknown() as a built-in plan modifier, which will automatically replace an unknown value in the plan with the value from the state. This mimics the behavior of computed and optional+computed values in Terraform Plugin SDK versions 1 and 2. Provider developers will likely want to use it for "write-once" attributes that never change once they're set in state. (#204)
tfsdk: Support list and set blocks in schema definitions (#188)

ENHANCEMENTS:

diag: Added WithPath() function to wrap or overwrite diagnostic path information. (#219)
tfsdk: The Config, Plan, and State type GetAttribute methods can now be used to fetch values directly into attr.Value implementations and Go types. (#167)

BUG FIXES:

tfsdk: Fetch null values from valid missing Config, Plan, and State paths in GetAttribute() method (#185)
types: Ensure Float64 Type() method returns Float64Type (#202)
types: Prevent panic with uninitialized Number Value (#200)
types: Prevent panics when ValueFromTerraform received nil values (#208)

0.4.2 (September 29, 2021)

BUG FIXES:

Fix bug in which updating Computed-only attributes would lead to a "Provider produced inconsistent result after apply" error (#176/#184)

0.4.1 (September 27, 2021)

NOTES:

Upgraded to terraform-plugin-go v0.4.0 which contains its own breaking changes. Please see https://github.com/hashicorp/terraform-plugin-go/blob/main/CHANGELOG.md#040-september-24-2021 for more details. (#179)

0.4.0 (September 24, 2021)

BREAKING CHANGES:

attr.Type implementations must now have a String() method that returns a human-friendly name for the type. (#120)
tfsdk: Resource implementations must now include the ImportState(context.Context, ImportResourceStateRequest, *ImportResourceStateResponse) method. If import is not supported, call the ResourceImportStateNotImplemented() function or return an error. (#149)

FEATURES:

tfsdk: Support resource import (#149)
types: Support Set and SetType (#126)
types: Support for Float64, Float64Type, Int64, and Int64Type (#166)

ENHANCEMENTS:

Added a tfsdk.ConvertValue helper that will convert any attr.Value into any compatible attr.Type. Compatibility happens at the terraform-plugin-go level; the type that the attr.Value's ToTerraformValue method produces must be compatible with the attr.Type's TerraformType(). Generally, this means that the attr.Type of the attr.Value and the attr.Type being converted to must both produce the same tftypes.Type when their TerraformType() method is called. (#120)

BUG FIXES:

attr: Ensure List types implementing attr.TypeWithValidate call ElementType validation only if that type implements attr.TypeWithValidate (#126)
tfsdk: (Plan).SetAttribute() and (State).SetAttribute() will now create missing attribute paths instead of silently failing to update. (#165)

0.3.0 (September 08, 2021)

BREAKING CHANGES:

Methods on the tfsdk.Config, tfsdk.Plan, and tfsdk.State types now return []*tfprotov6.Diagnostic instead of error (#82)
Most uses of []*tfprotov6.Diagnostic have been replaced with a new diag.Diagnostics type. Please update your type signatures, and use one of the diags.New* helper functions instead of constructing *tfprotov6.Diagnostics by hand. (#110)
The schema.Attribute and schema.Schema types have been moved to tfsdk.Attribute and tfsdk.Schema. No changes beyond import names are required. (#77)
With the release of Go 1.17, Go 1.17 is now the lowest supported version of Go to use with terraform-plugin-framework. (#104)
attr.Value implementations must now implement a Type(context.Context) method that returns the attr.Type that created the attr.Value. (#119)

FEATURES:

Added support for ModifyPlan functions on Resources. (#90)
Introduced first-class diagnostics (diag package). (#110)
Support attr.Type validation (#82)
tfsdk: Attributes, Data Sources, Providers, and Resources now support configuration validation (#75)

ENHANCEMENTS:

Added a tfsdk.ValueAs helper that allows accessing an attr.Value without type assertion, by using the same reflection rules used in the Config.Get, Plan.Get, and State.Get helpers. (#119)
Errors from methods on the tfsdk.Config, tfsdk.Plan, and tfsdk.State types now include rich diagnostic information (#82)
tfsdk: Validate Attribute defines at least one of Required, Optional, or Computed (#111)

BUG FIXES:

tfsdk: Diagnostics returned from (Plan).SetAttribute() and (State).SetAttribute() reflection will now properly include attribute path (#133)
tfsdk: Don't attempt validation on the nested attributes of a null or unknown SingleNestedAttribute (#118)
tfsdk: Return warning diagnostic when using Attribute or Schema type DeprecationMessage field (#93)

0.2.0 (July 22, 2021)

ENHANCEMENTS:

Added tfsdk.NewProtocol6Server to return a tfprotov6.ProviderServer implementation for testing and muxing purposes. (#72)
Added support for MapNestedAttributes. (#79)
Responses now default to returning the current state, meaning state will only change when provider developers actively change it. Previously, an empty state value would be returned, which caused problems. (#74)

0.1.0 (June 24, 2021)

FEATURES:

Added interfaces extending the attr.Type interface to include attribute and element types. (#44)
Added state, config, and plan types, and support for getting values from them. (#46)
Added support for Object types. (#38)
Added support for bools, numbers, and strings. (#29)
Added support for defining schemas and attributes. (#27)
Added support for lists. (#36)
Added support for maps. (#37)
Added support for provider, resource, and data source types. (#32)
Added the ability to serve providers. (#45)
