Terraform 1 8

Terraform 1.8

This overview applies when the project's target Terraform version is at least 1.8.

Provider capabilities

• Providers can contribute configuration-language functions, called with provider::provider_name::function_name().
• Providers can declare supported resource-type conversions so a moved block can transfer ownership of one remote object between different resource types.
• issensitive(value) reports whether a value carries the sensitive mark.

Testing and configuration generation

• File-level variables in .tftest.hcl files can refer to global variables.
• Import-driven configuration generation recognises JSON strings and emits jsonencode expressions for more maintainable generated configuration.
• The built-in terraform provider exposes decode_tfvars, encode_tfvars, and encode_expr functions for specialised tooling that reads or writes Terraform expression formats.

Plans and provider locks

• Plan JSON includes applyable and complete. applyable indicates whether applying the plan is meaningful; complete = false indicates that another plan and apply round may be required for convergence.
• terraform providers lock -enable-plugin-cache permits lock generation to use the configured global provider cache.
• List changes of equal length render as element-by-element diffs using correlated indices.
