 ## [Unreleased]
 
+### Changed
+- **Join request display and settings workflow** – Improved join request rendering and related settings behavior in one cohesive update:
+  - Join request fields now respect their configured field types in the details view.
+  - Custom field labels in join request views were standardized.
+  - Join request field formatting was corrected for more consistent output.
+  - Join link settings now include a direct "Open" action in addition to copy/share workflows.
+
 ### Fixed
 - **Runtime ENV handling** – Empty or invalid environment variables (e.g. `SMTP_PORT=`, `PORT=`, `POOL_SIZE=`, `DATABASE_PORT=`) no longer cause `ArgumentError` at boot. Instead raises clear errors for required vars set but empty (e.g. DATABASE_HOST, PHX_HOST/DOMAIN, SECRET_KEY_BASE).
+- **PostgreSQL 18 Docker volume path** – Corrected the database volume path to match PostgreSQL 18 expectations.
+
+### Dependency updates
+- Mix dependencies were updated.
+- Renovate Docker image was updated to `v43.165`.
+- Rauthy Docker image was updated to `v0.35.1`.
+- `just` was updated to `v1.50.0`.
