1.2.0 (Unreleased)

NEW FEATURES:

• precondition and postcondition check blocks for resources, data sources, and module output values: module authors can now document assumptions and assertions about configuration and state values. If these conditions are not met, Terraform will report a custom error message to the user and halt further evaluation.

ENHANCEMENTS:

• The "Invalid for_each argument" error message for unknown maps/sets now includes an additional paragraph to try to help the user notice they can move apply-time values into the map values instead of the map keys, and thus avoid the problem without resorting to -target. [GH-30327]

BUG FIXES:

• Terraform now handles type constraints, nullability, and custom variable validation properly for root module variables. Previously there was an order of operations problem where the nullability and custom variable validation were checked too early, prior to dealing with the type constraints, and thus that logic could potentially "see" an incorrectly-typed value in spite of the type constraint, leading to incorrect errors. [GH-29959]
• terraform show -json: JSON plan output now correctly maps aliased providers to their configurations, and includes the full provider source address alongside the short provider name. [GH-30138]
