Changes in version 0.3.0 (2026-01-12)                  

Major Features

  - Batch Translation Mode: New translation mode that sends all items in
    a single LLM call per stage (forward/back/recon) for faster
    processing and better context-aware translations
  - Multi-Sheet Excel Support: Can now select and translate individual
    sheets or all sheets at once from Excel files with multiple sheets
  - Custom Model Input: Model selection fields now accept custom model
    names typed by users, allowing use of newly released models without
    app updates

    during translation while maintaining correct row alignment

    is being processed during multi-sheet translations

    whether Batch or Item-by-item mode was used

    Selection and Prompt logs
