1.16.0 (August 26, 2026)

NEW FEATURES:

• Terraform now stores planned private data for providers, allowing provider-specific state to be preserved across plan and apply. (#​37986)

• terraform_data: The new store block can hold ephemeral and sensitive values across plan and apply. (#​38298)

• Providers can now use nested blocks as computed values (#​38305)

• import: import blocks inside modules are now supported. (#​38352)

• Terraform is now available as a pre-built binary for Linux s390x (zLinux). (#​38384)

• Resource action triggers can now use on_failure modes of halt, taint, or continue. (#​38722)

ENHANCEMENTS:

• state show: The state show command can now produce machine-readable output when supplied with the -json flag (#​23940)

• workspace: The workspace list command can now produce machine-readable output when supplied with the -json flag (#​38397)

• test: Terraform now reports which resources were left behind when skip_cleanup is set. (#​38449)

• stacks: Action configurations now have access to a caller symbol containing the object value of the calling resource. (#​38668)

• Actions can now use before_destroy and after_destroy events. (#​38668)

• cloud: Terraform now displays a summary of policy evaluation outcomes for plan and apply runs against HCP Terraform. (#​38715)

• policy: Terraform now resolves policy plugin credentials from the configured cloud or remote backend during init, plan, and apply, rather than requiring the plugin to read credentials itself. (#​38716)

• graph: The terraform graph command can now output graphs in Mermaid format using the -format=mermaid flag. (#​38719)

• Child module outputs with unreferenced deprecated nested attributes no longer return deprecation warnings. (#​38778)

• Resource lifecycle blocks now support destroy = false to prevent a resource from being destroyed. (#​38784)

• The contains() function can now test for null values. (#​38792)

• console: The terraform console command now accepts an optional -scope=<module address> flag, which can be used to evaluate expressions within the scope of a module or a specific module instance. (#​31861)

• -invoke can now be combined with -target to specify the calling resource instance when multiple resources trigger the same action. (#​38845)

• The terraform stacks command now automatically infers the target hostname from the local credentials file (credentials.tfrc.json) when neither TF_STACKS_HOSTNAME nor TF_CLOUD_HOSTNAME is set (#​38896)

BUG FIXES:

• import blocks now correctly respect provider local names. (#​38338)

• terraform apply no longer panics when the plan contains a no-op change for a deposed resource that has lifecycle.precondition or lifecycle.postcondition blocks. (#​38586)

• workspace: Terraform now raises an error if an invalid workspace name becomes selected due to out-of-band changes. (#​38594)

• test: Terraform now raises a warning when a file referenced via the -filter flag does not exist. (#​38603)

• init: Terraform no longer removes locks from the dependency lock file for providers configured as dev_override. (#​38634)

• init: Terraform now warns when unmanaged providers are in use and may impact provider installation. (#​38656)

• Actions are now invoked with respect to all resource dependencies. (#​38668)

• Terraform now returns the correct error when an import target exists in state but has no corresponding configuration. (#​38782)

• The merge() function no longer panics when passed null objects. (#​38792)

• Allow underscores in provider source address namespaces, so private registry provider addresses are no longer rejected as invalid (#​38894)

• test: Optional ephemeral values do not have to be set at plan time (#​38974)

NOTES:

• init: Errors due to incompatible -upgrade and -lockfile=readonly flags are now raised earlier in the init process. (#​38561)

UPGRADE NOTES:

• bastion_host_key is now correctly applied by provisioners. Review your provisioner configurations to verify the configured key is correct before upgrading. (#​38318)
