Highlights
- Significant macOS performance and stability improvements: A wide range of fixes address chat scroll freezes, sidebar re-render cascades, main thread blocking during file I/O, and SwiftUI invalidation issues — resulting in a noticeably smoother and more responsive experience.
- Outlook messaging support: Vellum can now connect to Microsoft Outlook as a messaging provider, joining the existing Slack integration and expanding where the assistant can be reached.
- Smarter assistant context and memory: The assistant now seeds capability memories for all skills (including bundled ones) and CLI commands at startup, improves semantic search, and better manages context window estimates — helping it make more informed decisions about what tools and actions to use.
- Security hardening across the assistant and gateway: Several security improvements landed, including removal of the
dangerouslySkipPermissionsfeature, stricter risk classifications for CLI subcommands and hooks directory mutations, validation of symlink targets before spawning, and tightened admin route authorization. - Polished UI components and design consistency: New and updated components — including a redesigned skill detail page, a shared file browser, improved dropdown and navigation items, a context window indicator, and a consistent page container layout — bring a more cohesive look and feel across the app.
