      • Changelog

      Upcoming features: Create a local desktop client; add AI polishing for translated subtitles.

      • 2026.05.06: Service catalog v2 — major release.
        • New MT service: TranslateGemma (Google's translation-specialized Gemma derivative, self-hosted)
        • New LLM providers: MiniMax, Tencent Hunyuan, Baidu ERNIE (Qianfan), Cohere
        • Quick-pick regional endpoints across providers (Mainland CN / International / US, etc.)
        • Thinking mode + reasoning effort (low / medium / high) for DeepSeek, NVIDIA NIM, Claude, etc.
        • New "skip system message" toggle for Custom (OpenAI-compatible), compatible with Gemma chat templates
        • URL field auto-completes /v1/chat/completions on blur — guards against misusing Responses / legacy completions
        • Standalone Prompt preset management (decoupled from LLM API presets, freely combinable)
        • Main page now shows an API Status badge plus a one-click source/target language swap
        • Fixed: cache writes were happening even when caching was disabled; LLM-backed MT (Qwen-MT, TranslateGemma) retry behavior now aligns with LLM
      • 2025.07.29: Added context-aware translation for AI mode.
      • 2025.03.20: Completed i18n (internationalization); fixed known bugs including cache key issues; project open-sourced.
      • 2025.02.28: Added support for custom system and user prompts for LLM model translations.
      • 2025.02.27: Enhanced timeline compatibility for bilingual subtitles, supporting formats that omit the default hour, exceed 100 hours, and display 1 to 3 millisecond digits.
      • 2025.02.21: Added support for batch translating into multiple languages at once.
      • 2025.02.08: Fixed encoding detection issue in multi-file mode; added interfaces for OpenAI and Groq (feedback for other interfaces is welcome).
      • 2025.02.06: Added Siliconflow API; added temperature setting for LLM models to control AI translation randomness.
      • 2025.02.05: Fixed an issue where blank lines and DeepLX line breaks were ignored during chunked translation; added separate chunk translation parameters for different APIs.
      • 2025.01.18: Added support for automatic encoding detection for uploaded files; added an option to display translated content above or below the original subtitle line.
      • 2025.01.13: Added a self-hosted DeepLX interface; refactored translation API settings into a separate component to simplify frontend logic.
      • 2025.01.10: Added DeepSeek translation interface. Fixed DeepLX subtitle line break issue; improved translation language search and detection (added support for searching in Chinese/English).
      • 2024.12.19: Added automatic detection for single-file vs. multi-file mode; added automatic source language detection; improved file export naming convention for single-file translations.
      • 2024.12.12: Used p-limit to restrict concurrency, significantly reducing errors with free APIs.
      • 2024.10.12: Added a custom delay setting for the GTX API. (Based on feedback, the previous setting could easily hit the limit after 150 requests, while lower numbers didn't require adjustment).
      • 2024.09.08: Added batch translation limits for the GTX API to ensure stability. Added support for Traditional Chinese.
      • 2024.09.07: Improved recognition of WebVTT format; set .ass as the default format for bilingual subtitles and added compatibility for multi-line bilingual processing.
      • 2024.09.06: Added local caching for translation results to speed up the translation of repeated content.
      • 2024.09.05: Added functionality to skip purely numeric or character-based content to avoid unnecessary translations.

      • 2024.07.11: Added automatic subtitle format matching in single-file mode.
      • 2024.07.06: Added support for .vtt and .ass subtitle formats.
      • 2024.07.05: Expanded supported languages for subtitle translation to 35.
      • 2024.06.26: Added a feature to extract only the subtitle content.
