terraform-linters/tflint v0.51.0

on GitHub

What's Changed

This release includes many new features including parallelization of recursion inspection and support for Terraform v1.8.

Also, please be aware that there are important changes regarding licensing. TFLint has updated the embedded Terraform package to the latest version for Terraform v1.6+ support. As a result, we will be affected by Terraform's license change to BUSL announced by Hashicorp in August 2023.

Most of the code in TFLint is still licensed under MPL 2.0, but some files under the Terraform package are now licensed under BUSL 1.1. This means that release binaries are bound by both licenses and may be subject to Hashicorp's BUSL restrictions. If you have concerns about this change, we recommend reviewing the licensing implications before updating. Please note that we cannot provide legal advice.

Please refer to the discussion in #1826 and #1878 for details.

Enhancements

• config: Add TFLint required_version settings by @wata727 in #2027
  • The required_version attribute can now be set in .tflint.hcl. This is useful for enforcing the version of TFLint that is actually used.
• plugin: Add support for host-specific GitHub tokens by @wata727 in #2025
  • Environment variables like GITHUB_TOKEN_example_com have been introduced for GitHub Enterprise Server support.
• Recursive inspection in parallel by @wata727 in #2021
  • The --recursive inspection now runs in parallel according to the number of CPU cores by default. The number of parallels can be changed with --max-workers.
• terraform: Add support for Terraform v1.6/v1.7/v1.8 by @wata727 in #2030
  • New Terraform features are now supported, including provider-defined functions. Please note that support for provider-defined functions requires the latest HCL parser, so you may need to update your plugin versions.
  • Updated embedded Terraform packages to support Terraform v1.6+. As a result, TFLint now includes code for Hashicorp's BUSL 1.1.

Changes

• Add warnings to --module/--no-module and module attribute by @wata727 in #1951
  • If you see a warning, use --call-module-type instead. The --module is equivalent to --call-module-type=all and the --no-module is equivalent to --call-module-type=none. This also applies to .tflint.hcl.
