Release Notes

hashicorp/terraform (terraform)

v1.15.2

Compare Source

1.15.2 (May 6, 2026)

ENHANCEMENTS:

• stacks: add ouput values to plan component instance change description (#​38360)

BUG FIXES:

• Avoid printing warnings from 'terraform output -json' (#​38530)

v1.15.1

Compare Source

1.15.1 (May 1, 2026)

BUG FIXES:

• Fixed crash when configuration has an invalid action_trigger nested block in data or ephemeral lifecycle blocks (#​38402)

• validate: Removed validation of attributes inside backend blocks due to incompatibility with workflows using the -backend-config flag. (#​38466)

• Fix non-const variable checks on init (#​38470)

• Avoid warnings in 'terraform output -raw' (#​38487)

• Ignore undeclared variable values from the cloud backend (#​38490)

• Fix panic for types modules with no expanded instances (#​38491)

• Fixed "unknown provider function" errors occurring during init (#​38472)

• init: Fixed a bug that impacted use of provider pre-releases during init (#​38496)

v1.15.0

Compare Source

1.15.0 (April 29, 2026)

NEW FEATURES:

• We now produce builds for Windows ARM64 (#​32719)

• You can set a deprecated attribute on variable and output blocks to indicate that they are deprecated. This will produce warnings when passing in a value for a deprecated variable or when referencing a deprecated output. (#​38001)

• backend/s3: Support authentication via aws login (#​37976)

• validate: The validate command now checks the backend block. This ensures the backend type exists, that all required attributes are present, and that the backend's own validation logic passes. (#​38021)

• convert function, which allows for precise inline type conversions (#​38160)

• Terraform now supports variables and locals in module source and version attributes (#​38217)

ENHANCEMENTS:

• config: output blocks now can have an explicit type constraints (#​36411)

• ssh-based provisioner (file + remote-exec): Re-enable support for PowerShell (#​37794)

• terraform init log timestamps include millisecond precision (#​37818)

• init: skip dependencies declared in development override. This allows you to use terraform init with developer overrides and install dependencies that are not declared in the override file. (#​37884)

• Terraform Test: Allow functions within mock blocks (#​34672)

• improve detection of deprecated resource attributes / blocks (#​38077)

• Deprecation messages providers set on resources / blocks / attributes are now part of the deprecation warning (#​38135)

• Include which attribute paths are marked as sensitive in list_start JSON logs (#​38197)

• Add input variable validation for Stacks (#​38240)

• When comparing a container value to null, only top level marks are now considered for the result. (#​38270)

• As part of supporting variables in module sources, most commands now accept variable values (#​38276)

BUG FIXES:

• testing: File-level error diagnostics are now included in JUnit XML skipped test elements, ensuring CI/CD pipelines can detect validation failures (#​37801)

• A refresh-only plan could result in a non-zero exit code with no changes (#​37406)

• cli: Fixed crash in terraform show -json when plan contains ephemeral resources with preconditions or postconditions (#​37834)

• cli: Fixed terraform init -json to properly format all backend configuration messages as JSON instead of plain text (#​37911)

• state show: The state show command will now explicitly fail and return code 1 when it fails to render the named resources state (#​37933)

• apply: Terraform will raise an explicit error if a plan file intended for one workspace is applied against another workspace (#​37954)

• lifecycle: replace_triggered_by now reports an error when given an invalid attribute reference that does not exist in the target resource (#​36740)

• backend: Fix nil pointer dereference crash during terraform init when the destination backend returns an error (#​38027)

• stacks: send progress events if the plan fails for better UI integration (#​38039)

• stacks: component instances should report no-op plan/apply. This solves a UI inconsistency with convergence destroy plans (#​38049)

• backend/http: Return conflicting lock info from HTTP backend instead of the lock that failed to be taken (#​38144)

• states: fixed a bug that caused Terraform to be unable to identify when two states had different output values. This may have caused issues in specific circumstances like backend migrations. (#​38181)

• cloud: terraform cloud and registry discovery network requests are now more resilient, making temporary network or service related errors less common (#​38064)

• Enable formatting of .tfquery.hcl files by terraform fmt (#​38398)

• Fix validate not returning JSON for some early diagnostics (#​38400)

• Fix Terraform Stacks plugin installation error (#​38406)

NOTES:

• command/init: Provider installation was refactored to enable future enhancements in the area. This results in different order of operations during init and 2 new log messages replacing one (initializing_provider_plugin_message). The change should not have any end-user impact aside from the init command output. (#​38227)

UPGRADE NOTES:

• backend/s3: The AWS_USE_FIPS_ENDPOINT and AWS_USE_DUALSTACK_ENDPOINT environment variables now only respect true or false values, aligning with the AWS SDK for Go. This replaces the previous behavior which treated any non-empty value as true. (#​37601)
