# 0.14.0 (Unreleased)

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. [GH-182]

# 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)
