Version v0.38.3 of Dokku rejects per-app proxy settings for global‑only properties, corrects a reporting flag error on undeployed apps, renames app‑json report flags for consistency, and adds Docker healthchecks.

Why it matters: Patch to v0.38.3 if you configure global‑only proxy properties per app; otherwise treat as routine upgrade with no immediate action required.
