Highlights
- Personal Knowledge Base (PKB) introduced — Vellum now includes a reliable fact-recall system that files and retrieves important information across conversations, with improved memory extraction, deduplication, edit-history tracking, and a fully redesigned Memory inspector UI featuring compact list views, confidence bars, color-coded indicators, and an inline detail panel.
- Major chat performance improvements — Several significant hangs and layout bottlenecks in the macOS app have been resolved, including a 465-second conversation-switch freeze, a 118-second LazyVStack layout cascade, and recurring main-thread stalls caused by SwiftUI Observation cascades, Combine dispatch, and GeometryReader overhead.
- Subagent system expanded with roles, tool scoping, and inter-agent communication — Subagents now support typed roles with per-role tool allowlists, a new
notify_parenttool for communicating results back to a parent agent, label-based lookup as an alternative to UUIDs, and afile_listcore tool for directory listing within subagent contexts. - Email integration and new CLI commands — Vellum can now send, receive, register, and manage email directly through new
assistant emailCLI commands, alongside an inbound webhook endpoint. Additional CLI commands were added for streaming assistant events (vellum events), sending messages (vellum message), and managing user-defined routes. - Numerous stability and rendering fixes across macOS and iOS — Fixes include real-time streaming thinking blocks, preserved thinking block expansion state, improved markdown italic and emphasis rendering, better Anthropic prompt cache utilization with an append-only history approach, corrected sidebar pinned conversation display, and more reliable scroll and layout behavior throughout the app.
