Release Notes Published

New Features

  • App listing responses now include richer app details (app_metadata, branding, and labels), so clients can render more complete app cards without extra requests. (#11706)
  • Commit co-author attribution now uses a Codex-managed prepare-commit-msg hook, with command_attribution override support (default label, custom label, or disable). (#11617)

Bug Fixes

  • Removed the remote_models feature flag to prevent fallback model metadata when it was disabled, improving model selection reliability and performance. (#11699)

Chores

  • Updated Rust dependencies (clap, env_logger, arc-swap) and refreshed Bazel lock state as routine maintenance. (#11888, #11889, #11890, #12032)
  • Reverted the Rust toolchain bump to 1.93.1 after CI breakage. (#11886, #12035)
