MimikaStudio v2026.03.8 Release Notes

Release Date: March 18, 2026
Platform: macOS (Apple Silicon)

---

What's Fixed In v2026.03.8

• Restored Hebrew Dicta diacritization for Chatterbox Multilingual after the MLX backend migration.
• Fixed the regression where Hebrew Chatterbox generation could silently fall back to a broken tokenizer path and log:
  Dicta.__init__() missing 1 required positional argument: 'model_path'
• Rewired MimikaStudio's Chatterbox engine to preload the Dicta ONNX model into the tokenizer module actually used by the MLX runtime before model load.

---

User Impact

• Hebrew Chatterbox smoke tests now run without the Dicta initialization warning.
• Full Hebrew voice-clone renders complete successfully again on the patched MLX path.
• Existing Hebrew Dicta installs are now picked up from:
  • DICTA_ONNX_MODEL_PATH
  • bundled app model path
  • Mimika runtime data model path

---

Technical Notes

• Updated the backend Chatterbox engine to resolve an explicit Dicta ONNX path instead of relying on a zero-argument Dicta() constructor.
• Patched both supported tokenizer import paths so Hebrew preprocessing is applied consistently across the MLX-backed Chatterbox runtime.
• Verified generation with:
  • a short Hebrew smoke test
  • a full Hebrew parashat_hashavua.txt render using a custom uploaded reference voice

---

Previous Release: v2026.03.7

• Sandboxed release entitlement update and release-build hardening.
