CDK Terrain (CDKTN) v0.22.0 shipped on 2026-02-17 as the first release of the community continuation of CDK for Terraform (CDKTF). v0.22.1 followed on 2026-03-27. To move an existing cdktf project over, follow the migration guide.

​
Breaking changes

​
Packages renamed from cdktf to cdktn (v0.22.0)

All packages have new names:
  • cdktf → cdktn
  • cdktf-cli → cdktn-cli
  • @cdktf/* → @cdktn/*
The old packages are deprecated. Internal symbols and logical IDs are unchanged, so your Terraform state is unaffected. CDKTN still reads cdktf.json, writes to cdktf.out/, and honors CDKTF_* environment variables. The migration guide lists everything that stays the same.

​
Pre-built providers require cdktn (v0.22.0)

Pre-built providers now declare cdktn as their peer dependency, so each one shipped as a new major version under @cdktn/provider-*. If you mix old @cdktf/provider-* packages with cdktn, you can hit type errors. See Transitional Period.

​
Features

​
Java and .NET packages published again (v0.22.1)

cdktn Java artifacts are published to Maven Central, and .NET packages to NuGet.org.

​
Generated TypeScript without parameter properties (v0.22.1)

The provider generator no longer emits TypeScript parameter properties (for example constructor(private x: string)) in generated structs (cdk-terrain#43). That syntax can’t be erased, so removing it brings generated code closer to running directly in Node.js with type stripping.

​
Notable fixes

  • cdktn init (v0.22.1): the TypeScript template pins TypeScript 5.x, because ts-jest didn’t support TypeScript 6 yet. v0.25 moved the template to tsx and TypeScript 6 (cdk-terrain#396).
  • TerraformOutput (v0.22.1): no longer triggers the Node.js DEP0044 deprecation warning about util.isArray.
  • Provider generation (v0.22.1): Terraform variable types with inline comments that contain brackets now parse correctly.
  • Go (v0.22.1): Go module releases were fixed.
See the CHANGELOG for the complete list.

​
Pre-built providers

These changes landed in the pre-built provider packages while v0.22 was current:
  • Switched to cdktn: the pre-built providers depend on cdktn and cdktn-cli ^0.22.0 instead of cdktf and cdktf-cli.
  • Providers imported into cdktn-io: these providers moved from the archived CDKTF organization and are now maintained under cdktn-io as @cdktn/provider-* packages: acme, azuread, cloudflare, databricks, datadog, hcp, helm, newrelic, pagerduty, postgresql, snowflake, and vault.
