[4.2.0] - Release Notes

This release upgrades the biometric engine and introduces several quality and reliability improvements: a unit testing framework, proper error handling for malformed inputs, environment variable configuration precedence, and an updated Docker base image.

Added

  • Environment variable configuration precedence using the FACEPHI_BACKEND1N_REST_* prefix. Environment variables now have the highest priority in the configuration chain.

Changed

  • Upgrade biometric engine.

Fixed

  • Malformed Base64 and JSON inputs in /extract and /search endpoints now return HTTP 400 (Bad Request) instead of HTTP 500 (Internal Server Error).
  • Docker base image updated from Ubuntu 24.04 to Ubuntu 26.04 for improved security.
