What's New in v0.4.5

Localization (36 Languages)

  • Full UI translation — all user-facing strings extracted into Strings.resx
  • 36 language packs — Arabic, Bengali, Chinese (Simplified), Czech, Danish, Dutch, French, German, Greek, Hebrew, Hindi, Indonesian, Italian, Japanese, Korean, Malay, Marathi, Persian, Polish, Portuguese, Punjabi, Russian, Spanish, Swahedi, Swedish, Tamil, Telugu, Thai, Turkish, Ukrainian, Urdu, Vietnamese, and more
  • Automatic language detection — app language follows OS locale (CurrentUICulture)
  • RTL support — Arabic, Hebrew, Urdu, and Persian layouts mirror automatically
  • {lang:Localize} markup extension for XAML + Loc.GetString() for ViewModels

Voice Engine Fixes

  • RustTtsWrapper 0.3.12 — fixes tts_set_voice() selecting wrong Azure voice, tts_speak_ssml() for Azure, and GetVoices() crash for cloud engines
  • Azure voice activation fix — Azure voice tokens now include EngineType in VoiceGardenConfig, fixing "Invalid VoiceGardenConfig configuration" errors
  • PUA sentinel for inline SSML — web apps using Web Speech API can embed SSML via Unicode Private Use Area characters:
    • \uE000\uE001\uE002 prefix = SSML mode
    • \uE000\uE001\uE003 prefix = Speech Markdown mode
    • Other SAPI voices ignore the PUA characters harmlessly
  • Cloud engines off by default — paid cloud engines (Azure, OpenAI, Google, etc.) disabled on fresh install; SherpaOnnx (offline) and Edge (free) remain on

MMS Model Data Fix

  • 1143 MMS models now searchable — language metadata was blank due to mismatched JSON field names ("Iso Code" vs "lang_code"). Now all MMS models have proper language names, codes, and countries
  • Kurdish, Aceh, Abidji, and 1100+ other languages now appear correctly in the model browser

Credential Management

  • Auto-save credentials — API keys entered in Configure Credentials or Configure Voices are saved to registry immediately
  • Dual-screen sync — credentials entered in either screen are shared via the same registry keys
  • Azure legacy compatibility — reads from both new ({Engine}VoiceKey) and legacy (AzureVoiceKey) registry paths

Installer Fixes

  • Error 1721/1722 fix — Return="ignore" on regsvr32 custom actions prevents install/uninstall failure when DLL dependencies are missing
  • Upgrade ghost fix — IgnoreRemoveFailure="yes" + Schedule="afterInstallFinalize" allows clean installs even when previous broken versions left stuck MSI registrations

Onboarding

  • 3-page wizard — Welcome (logo + intro), Getting Started (install adapter, download models, language compatibility tip), Privacy (analytics opt-in)
  • Version-gated — bump CurrentOnboardingVersion to force all users to see updated content
  • Analytics consent preserved — PostHog analytics ID persists across reinstalls
