Vellium has promoted its previous beta build to the first stable v1.0.0 release, marking a significant milestone for the local-first desktop workspace designed for writing, roleplay, and knowledge management with local LLMs.
- The update focuses on security and stability, implementing stricter Electron security policies, request origin validation, tighter plugin manifest checks, and a global React error boundary.
- Chat export has been rebuilt as a typed JSON pipeline with separated server-side logic and additional tests, while the roleplay prompt engine received hardening for more predictable tool handling.
- Users can now generate complete UI color themes from selected wallpapers, which are applied across the entire workspace rather than just changing accent colors.
- The release includes unified styling for key screens, fixes for the model picker visibility, and corrections to message scrolling behavior.
The developer notes that because this release touched a large part of the desktop stack, feedback regarding packaged builds, local model compatibility, and UI issues is particularly valuable.
