What's New

Features & Improvements

  • Multi-API-Key rotation & throughput boost — configure multiple Agnes API keys (env + config, auto-dedup); requests rotate across keys via a KeyRing, and a 429 retry-on-key-switch mechanism instantly switches to the next key on rate-limit instead of backing off. Layered rate limiting gives video submissions a dedicated 1×Key/min bucket alongside the shared 20×Key×0.8/min bucket, roughly doubling achievable throughput with 2 keys.
  • User-supplied scene reference images (creative) — in creative long-video mode you can now upload a reference image per scene; the pipeline uses your image instead of AI-generated storyboard frames for that scene.
  • Task deletion (UI + API) — delete completed task folders from the task list or via DELETE /api/tasks/{id}; running tasks are protected with a clear error. The whole .working_dir stays clean.
  • API-key list & per-key removal — the settings panel now lists all configured keys with source badges (env/config); config-sourced keys can be removed individually without clearing everything.
  • Windows one-click start — start.bat for native Windows usage without Docker.

Refactoring & Optimizations

  • Frontend engineering re-architecture — the single-file index.html was refactored into a Vue 3 + Vite + TypeScript project (frontend/) with build output committed to static/. This brings type safety, modular components/composables/i18n, and a stable dev/build workflow (verified by CI's frontend-build job).
  • Unified image normalization module — new utils/image_normalizer.py normalizes reference/end-frame images to target size with black-bar padding before model submission, improving i2i/keyframes input consistency.

Bug Fixes

  • API-key plaintext leak — GET /api/config/keys now returns masked keys (sk-xxx...xxxx) with stable IDs instead of plaintext, preventing key disclosure via the API; deletion uses the stable ID.
  • Legacy task API compatibility — the legacy POST /api/tasks route now forwards scene_reference_images, fixing CI failures for older clients.
  • JSON robustness — optional json_repair fallback for LLM JSON responses with trailing commas / missing colons.
  • npm packaging — exclude runtime-generated static/generated/ from the published npm package.
