Terraform v1.15.3 addresses three operational issues: resource migration failures in deeply nested modules with implicit providers, provider installation crashes, and cloud backend flag forwarding. Upgrade if deploying nested module configurations or using cloud backends.

Why it matters: Upgrade to resolve nested module migration failures, provider installation crashes, and cloud backend flag forwarding. No specific adoption threshold; upgrade if experiencing these issues in production deployments.
