UltiVoice 3.0.0-alpha.2 Release Notes
Release notes for UltiVoice 3.0.0-alpha.2 — rebrand to UltiVoice, Voice Lab UI theme, docs site launch, activation improvements, and sidecar stability fixes.
Version: 3.0.0-alpha.2
Released: 5 June 2026
Platform: Windows x64
Highlights
Rebrand: Omnidub → UltiVoice
The product is now called UltiVoice. All in-app references, the installer filename, window title, and app data paths reflect the new name. Existing activations and license files migrate automatically on first launch of 3.0.0-alpha.2.
Voice Lab UI theme
New dark theme built around the “Voice Lab” palette:
- Primary accent: indigo
#6366f1 - Background: jet black
#0a0a0c - Typography: Plus Jakarta Sans (headings and body)
The redesign improves contrast ratios across the board and reduces eye strain during long editing sessions.
Documentation site
ultivoice.com/docs is now live with a full user guide:
- Getting Started — install, activate, first project.
- User Guide — complete dubbing workflow, voice cloning, subtitles, export.
- License & Activation — buying, activating, managing seats.
- Troubleshooting & FAQ — common issues and answers.
Activation flow improvements
- Activation code exchange is now faster — typical round-trip reduced from ~3 s to under 500 ms.
- Expired codes now show a clear error with a direct link to generate a new one.
- Offline grace period extended to 30 days for Professional tier.
Bug fixes
| Area | Fix |
|---|---|
| NVENC export | Fixed crash on videos longer than 45 minutes with H.265 NVENC encoding. |
| Sidecar stability | Fixed race condition on startup that caused the sidecar to fail silently when GPU initialisation took more than 10 s. |
| Translation | Fixed segment boundary misalignment when source audio contains long silences (>5 s). |
| ASS subtitles | Fixed incorrect character encoding for Vietnamese diacritics in exported .ass files. |
| Model detection | Fixed false “model missing” warning when model files were present but stored in a path containing non-ASCII characters. |
| License beacon | Fixed beacon retry loop that could spin at 100% CPU when the network was unreachable for more than 1 hour. |
Known issues
- ARM CPU (Snapdragon X): Pipeline crashes during Whisper inference. ARM support is planned post-1.0.
- Very long videos (>3 h): Translation stage may OOM on machines with <16 GB RAM. Workaround: split the video before importing.
- macOS / Linux: Not supported in the 3.x family. macOS build is on the roadmap.
Upgrade instructions
- Download the latest installer from ultivoice.com/download.
- Run the installer over your existing Omnidub/UltiVoice installation — it upgrades in place.
- On first launch, the app migrates app-data paths from
com.btgroup.omnidubtocom.btgroup.ultivoiceautomatically. - No reactivation is required.
