Version 4.12.1 validates redirect destinations and connects to the address that passed the URL policy.

- Who it helps
- Administrators running LocalAI with externally supplied media.
- Availability
- Version 4.12.1 is published as a security-only patch. Installation and deployment compatibility were not tested.
Redirects and destination checks
The release validates each redirect target, treats two additional address ranges as non-public, and connects to the validated address. This affects media URLs supplied to supported endpoints.
