[0.2.1] - 2026-04-26
Features
- VoxCPM2 TTS provider with voice cloning β MultiMind Classroom adapts to user-managed VoxCPM backends (vLLM-Omni, Nano-VLLM, official Python API). Clone any voice from a reference audio clip you upload or record in the browser, or let Auto Voice generate a fitting voice from each agent's persona at synthesis time. Voice profiles are stored locally to keep the serverless setup model. The Agent Bar exposes a searchable, previewable voice picker that draws from the global VoxCPM voice pool [#496](https://github.com/THU-MAIC/MultiMind Classroom/pull/496)
- Per-model thinking configuration β First-class metadata for each model's reasoning capability (effort levels, on/off toggle, adjustable budget, or fixed thinking) flows through chat and all generation paths and is mapped to the right provider-specific request fields (Anthropic
thinking, OpenAIreasoning, etc.). The model selector becomes a unified provider/model/thinking popover with compact search and a much smaller toolbar footprint [#494](https://github.com/THU-MAIC/MultiMind Classroom/pull/494) - End-of-course completion page with persistent quiz state β When the outline is fully materialized, students see a course-complete view with quiz score card, scene-type stat cards, and a (motion-respecting) confetti celebration. Quiz answers persist on submit and grading results persist on completion, so navigating away and back restores the reviewing state with AI feedback intact instead of resetting [#484](https://github.com/THU-MAIC/MultiMind Classroom/pull/484)
- Add latest released models including [GPT-5.5](https://github.com/THU-MAIC/MultiMind Classroom/pull/487), DeepSeek-V4 (
-pro,-flash), Xiaomi MiMo (mimo-v2.5-pro,mimo-v2.5), Tencent Hy3, and OpenRouter as a multi-provider gateway [#481](https://github.com/THU-MAIC/MultiMind Classroom/pull/481) [#487](https://github.com/THU-MAIC/MultiMind Classroom/pull/487) - Add OpenAI image generation (GPT-Image-2) as a media provider [#481](https://github.com/THU-MAIC/MultiMind Classroom/pull/481)
- Refresh built-in model registries across Anthropic, DeepSeek, Kimi, Qwen, MiniMax, Grok, OpenAI, GLM, SiliconFlow, and Ollama; persisted local settings now rehydrate in registry order so newly curated lists appear consistent without clearing state [#481](https://github.com/THU-MAIC/MultiMind Classroom/pull/481)
- Add inline search for recent classrooms on the home page with deferred filtering by name and description, keyboard-driven open/clear/collapse [#476](https://github.com/THU-MAIC/MultiMind Classroom/pull/476)
- Add Deep-Interactive badge on classroom thumbnails for sessions generated with Interactive Mode [#478](https://github.com/THU-MAIC/MultiMind Classroom/pull/478)
- Replace always-included media instruction blocks in generation prompts with conditional snippet includes gated on
imageEnabled/videoEnabledβ disabled capabilities are removed from the prompt entirely instead of relying on negative-override directives the model often ignored [#490](https://github.com/THU-MAIC/MultiMind Classroom/pull/490) (by @YizukiAme)
Bug Fixes
- Fix language drift between outline and scene generation by unifying the languageDirective across the pipeline so the same target language flows from outline planning through every per-scene call [#474](https://github.com/THU-MAIC/MultiMind Classroom/pull/474)
Other Changes
- Refactor whiteboard role prompts to file-based markdown templates and add a geometry-conflict detector (overlap, line-through-bbox, canvas clipping) that surfaces problems back to the model. Eval (flash, repeat 3, gemini-3.1-pro scorer) shows overall quality 5.4 β 6.1 and overlap 6.3 β 8.1 from prompt + detector alone [#485](https://github.com/THU-MAIC/MultiMind Classroom/pull/485)
- Migrate orchestration prompt builders (
buildStructuredPrompt,buildDirectorPrompt,buildPBLSystemPrompt) from inline TS template literals to file-based markdown templates underlib/prompts/, sharing the loader infrastructure with the generation pipeline.prompt-builder.ts890 β 314 lines; future content tweaks land as markdown edits [#459](https://github.com/THU-MAIC/MultiMind Classroom/pull/459)
[0.2.0] - 2026-04-20
