+
+BUG FIXES:
+ - Update `terraform-json` to support 0.15 changes in plan & config JSON output [GH-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) [GH-154]
+
 # 0.13.1 (March 29, 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.
