Also in this release
MemHub + APIFeatures7
- Autonomous discovery — a deep-research-style pass that decomposes a question, fills gaps, and ingests what it finds directly into a brain.
- A 14-day in-app trial for company orgs, with no card required.
- Referral codes are captured at signup.
- Documents in a brain are searched as part of chat retrieval.
- More document types accepted on upload.
- MCP server — inbound MCP server with read-only
search_memory. - MCP server —
save_artifact and add_memory write tools, plus a Claude Code turn-save hook.
Improvements4
- Slack binding status is readable, so the UI can tell whether Slack is actually connected.
- Billing — checkout returns
amount_total and currency, and has_billing_account is exposed for the trial-to-paid upgrade path. - Scoped data access to support the share modal.
- APIPairwise consolidation runs at flush, cutting duplicate facts.
Fixes5
- Chat — empty tool-loop responses no longer stall the conversation.
- Discovery — a friendly message when discovery finds nothing, rather than an empty screen.
- Documents — text extraction failures are handled gracefully; gating no longer blocks users entitled to a document.
- Onboarding — returning after exiting early puts you back into onboarding, and account deletion redirects to login.
- APIPersistence — NUL bytes are scrubbed and blank messages fall back to a zero vector instead of erroring.
Security2
- MCP server — transport-level auth with RFC 9728 discovery, and the public host is allowlisted in DNS-rebinding protection.
- APIPer-message rate limiting.
