# 0.23.1 (Unreleased)

BUG FIXES:

* Avoid closing stdio pipes early on graceful (SIGINT-based) cancellation ([#527](https://github.com/hashicorp/terraform-exec/pull/527))
  - This enables correct handling of graceful cancellation for recent versions of Terraform (1.1+). Older versions should use `SetEnableLegacyPipeClosing(true)` to avoid hanging on cancellation.

INTERNAL:

* bump github.com/cloudflare/circl from 1.6.0 to 1.6.1 ([#524](https://github.com/hashicorp/terraform-exec/pull/524))
* bump github.com/hashicorp/terraform-json from 0.24.0 to 0.26.0 ([#520](https://github.com/hashicorp/terraform-exec/pull/520) & [#529](https://github.com/hashicorp/terraform-exec/pull/529))
* bump github.com/zclconf/go-cty from 1.16.2 to 1.16.4 ([#522](https://github.com/hashicorp/terraform-exec/pull/522) & [#532](https://github.com/hashicorp/terraform-exec/pull/532))
* bump golang.org/x/net from 0.36.0 to 0.38.0 ([#515](https://github.com/hashicorp/terraform-exec/pull/515))

# 0.23.0 (April 10, 2025)

ENHANCEMENTS:
* Context cancellation on Unix systems will now send Terraform process SIGINT instead of killing it (which is otherwise default `os/exec` behaviour) ([#512](https://github.com/hashicorp/terraform-exec/pull/512))
  * You can change the default `60s` [`WaitDelay`](https://pkg.go.dev/os/exec#Cmd) via `SetWaitDelay(time.Duration)`
* error type returned from individual commands now implements `Unwrap` making it possible to pass it into [`errors.As`](https://pkg.go.dev/errors#As) and access lower-level error such as [`exec.ExitError`](https://pkg.go.dev/os/exec#ExitError) ([#512](https://github.com/hashicorp/terraform-exec/pull/512))

NOTES:
* go: Require Go 1.23 (previously 1.22) ([#499](https://github.com/hashicorp/terraform-exec/pull/511))
* Declare support of Terraform 0.12+ ([#510](https://github.com/hashicorp/terraform-exec/pull/510))

# 0.22.0 (January 21, 2025)

ENHANCEMENTS:
* tfexec: Add support for `terraform init --json` via `InitJSON` ([#478](https://github.com/hashicorp/terraform-exec/pull/478))

ENHANCEMENTS:
 - Add `JSONNumber` option to `Show` to enable `json.Number` representation of numerical values in returned `tfjson.Plan` and `tfjson.State` values ([#427](https://github.com/hashicorp/terraform-exec/pull/427))

# 0.19.0 (August 31, 2023)

ENHANCEMENTS:
 - Add support for `terraform test` command ([#398](https://github.com/hashicorp/terraform-exec/issues/398))

# 0.18.0 (February 20, 2023)

BREAKING CHANGES:

 - The following error types have been removed. These errors were based on regex parsing of Terraform CLI's human-readable output into custom error cases. ([#352](https://github.com/hashicorp/terraform-exec/issues/352))
   - `ErrConfigInvalid`
   - `ErrLockIdInvalid`

   - `ErrNoInit`
   - `ErrNoWorkspace`
   - `ErrStateLocked`

# 0.16.1 (April 13, 2022)

This patch version removes some unnecessary dependencies, and bumps Go module compatibility to 1.17.

# 0.16.0 (January 31, 2022)

This release removes the experimental `tfinstall` package. We recommend users of `tfinstall` switch to https://github.com/hashicorp/hc-install.

Please note also terraform-exec's Go version support policy, which, like Go's own release policy, commits to supporting the last two major releases. This means that currently terraform-exec requires Go 1.17 or later.

BREAKING CHANGES:

 - Remove `tfinstall` and `cmd/tfinstall` packages ([#235](https://github.com/hashicorp/terraform-exec/issues/235))
 - Remove support for `add` command ([#232](https://github.com/hashicorp/terraform-exec/issues/232))

FEATURES:

 - Add support for `graph` command ([#257](https://github.com/hashicorp/terraform-exec/issues/257))
 - Add support for `taint` command ([#251](https://github.com/hashicorp/terraform-exec/issues/251))
 - Add support for `untaint` command ([#251](https://github.com/hashicorp/terraform-exec/issues/251))
 - Add `ErrStatePlanRead`, returned when Terraform cannot read a given state or plan file ([#273](https://github.com/hashicorp/terraform-exec/issues/273))

# 0.15.0 (October 05, 2021)

FEATURES:

 - Add support for `providers lock` command ([#203](https://github.com/hashicorp/terraform-exec/issues/203))

ENHANCEMENTS:

 - Introduce `tfexec.ErrStateLocked` to represent locked state error ([#221](https://github.com/hashicorp/terraform-exec/issues/221))
 - Account for upcoming init error message change ([#228](https://github.com/hashicorp/terraform-exec/issues/228))

INTERNAL:

 - deps: Bump terraform-json to `0.13.0` to address panic & support v1 JSON format ([#224](https://github.com/hashicorp/terraform-exec/issues/224))

# 0.14.0 (June 24, 2021)

FEATURES:
 - Add `ProtocolVersion` to `ReattachConfig` struct, enabling provider protocol v6 support in reattach mode, provided that Terraform and the provider plugin are both using go-plugin v1.4.1 or later. This change is backwards-compatible, as zero values for this field are interpreted as protocol v5. ([#182](https://github.com/hashicorp/terraform-exec/issues/182))
 - Introduce `tfexec.Get()` for downloading modules ([#176](https://github.com/hashicorp/terraform-exec/issues/176))
 - Introduce `tfexec.Upgrade013()` ([#178](https://github.com/hashicorp/terraform-exec/issues/178))

INTERNAL:

 - Update `terraform-json` to account for changes in state & plan JSON output in Terraform v1.0.1+ ([#194](https://github.com/hashicorp/terraform-exec/issues/194))
 - Improve error message for incompatible Terraform version ([#191](https://github.com/hashicorp/terraform-exec/issues/191))

# 0.13.3 (April 23, 2021)

SECURITY:
 - `tfinstall`: The HashiCorp PGP signing key has been rotated ([HCSEC-2021-12](https://discuss.hashicorp.com/t/hcsec-2021-12-codecov-security-event-and-hashicorp-gpg-key-exposure/23512)). This key is used to verify downloaded versions of Terraform. We recommend all users of terraform-exec upgrade to v0.13.3 for this security fix. ([#166](https://github.com/hashicorp/terraform-exec/issues/166))

N.B. Versions of terraform-exec prior to v0.13.3 will continue to verify older versions of Terraform (up to and including v0.15.0) for a limited period. **Installation of Terraform using older versions of terraform-exec will stop working soon, and we recommend upgrading as soon as possible to avoid any interruption.**

# 0.13.2 (April 06, 2021)

BUG FIXES:
 - Update `terraform-json` to support 0.15 changes in plan & config JSON output ([#153](https://github.com/hashicorp/terraform-exec/issues/153))
 - Update `go-getter` to prevent race conditions where consumers would require `go-cleanhttp` `>=0.5.2` (which tfexec itself didn't depend on until now) ([#154](https://github.com/hashicorp/terraform-exec/issues/154))

# 0.13.1 (March 29, 2021)

BUG FIXES:
 - Bump version of terraform-json library to handle latest Terraform 0.15 output format ([#143](https://github.com/hashicorp/terraform-exec/issues/143))

NOTES:
 - This release no longer supports Go 1.12 (1.13+ is required)

# 0.13.0 (February 05, 2021)

Please note that this is the first release of terraform-exec compatible with Terraform 0.15. Running Terraform 0.15 commands with previous versions of terraform-exec may produce unexpected results.

 - Introduce `StateRm` method ([#122](https://github.com/hashicorp/terraform-exec/issues/122))

# 0.12.0 (December 18, 2020)

 - Introduce `Format` method with `io.Reader`/`io.Writer` interfaces ([#96](https://github.com/hashicorp/terraform-exec/issues/96))
 - Introduce `Validate` method with `tfjson` defined diagnostic types. Those types reflect exactly the types used in `terraform validate -json` output ([#68](https://github.com/hashicorp/terraform-exec/issues/68))
 - Introduce `StateMv` method ([#112](https://github.com/hashicorp/terraform-exec/issues/112))
 - Introduce `Upgrade012` method ([#105](https://github.com/hashicorp/terraform-exec/issues/105))

BUG FIXES:
 - Fix issue in tfinstall.GitRef where it assumed a `vendor` directory was present ([#89](https://github.com/hashicorp/terraform-exec/issues/89))
 - Use `json.Number` instead of `float64` when parsing state ([#113](https://github.com/hashicorp/terraform-exec/issues/113))
 - Support long variable names in `ErrMissingVar` ([#110](https://github.com/hashicorp/terraform-exec/issues/110))

# 0.11.0 (September 23, 2020)

FEATURES:
