Release Notes

Last updated: June 16, 2026

Release notes for Rhizar, including new features, improvements, and bug fixes.


June 26, 2026

Connected Tools

  • Added connected tools so agents can read from and act in external apps from within a chat
  • HubSpot and Notion are available to connect now, plus no-sign-in Web Search and Google Maps
  • Connecting an account once works across every agent in the workspace that has the tool enabled
  • Added a Tools section in account settings to connect, disconnect, reconnect, and check status per provider
  • Owners and admins choose which toolkits each agent exposes; members see the list read-only
  • Added a read-only admin catalog showing every toolkit, what it does, and its availability
  • Added an inline Connect step in chat that continues the action automatically once a needed account is connected
  • Tool activity now renders as plain-language cards ("Used Notion")

Action Approval

  • Actions that change data in a connected tool now pause for approval before running
  • Approval cards show the exact fields the agent will submit, not just its description
  • Approve or deny in one click, or choose "Other" to redirect the agent with a free-form instruction
  • Approval stays disabled until an account is connected, then auto-advances
  • Read-only actions (search, list, fetch) now run automatically; only changes wait for approval
  • Approvals, connections, and questions from one reply are now grouped into a single card

Clarifying Questions

  • The agent can now pause to ask a structured single- or multiple-choice question, with an "Other" free-text option

Web Search

  • The agent can now search the public web for current information beyond the knowledge base
  • Added a "Web search · N" chip under replies that opens a drawer listing the pages searched and read

Chats

  • Thinking now renders as separate blocks in the order things happened, each labeled "Thought for Xs"
  • Multi-step replies now render in correct chronological order instead of collapsing into one block
  • Actions that change data are no longer silently retried; only transient network errors retry
  • Shared and read-only chat views now show thinking blocks, tool cards, and questions
  • The message box is now held while an action or question is pending so nothing sends out of order
  • Loading states during agent responses have been optimized

Chat Attachments

  • Increased the Word document attachment limit to 10 mb (15 mb across all attachments)
  • Oversized files now show a clear dialog naming the file and the limit, at both pick and send time

Knowledge Base

  • Added a $50-per-day knowledge base processing cap per workspace to prevent runaway upload costs
  • Hitting the cap now shows a clear dialog and ingestion resumes automatically at midnight UTC

Admin Dashboard

  • Added a Tool Usage card on the admin and per-agent analytics pages showing how often each toolkit is used
  • Added admin visibility into the platform tool catalog and Arcade connection-quota status

Agent Settings

  • Agent instructions now have a character limit with a live counter that warns as you near the cap

May 14, 2026

Chats

  • Assistant messages that consulted other connected agents now show a "Consulted N" chip beneath the message that opens a drawer listing each consultation
  • The consultation drawer surfaces each consulted agent's name, the query the orchestrator sent, the answer it returned, the model used, and any sources the consulted agent grounded its answer in
  • The chip self-hides on messages where no agents were consulted, so it never adds visual noise to a normal reply
  • The assistant now consults connected specialist agents more readily and can ask several of them in parallel within a single reply, so cross-discipline questions surface the right perspectives without waiting on multiple turns

Sources & Citations

  • Every source passage now shows an explicit "via [Agent Name]" attribution badge, including main-agent sources — previously only connected-agent sources had the badge, so users had to infer "no badge means main agent"
  • Source passages in the Sources drawer now render with full markdown formatting (headings, lists, emphasis, line breaks) instead of being flattened to plain text
  • The "show surrounding context" view now displays an ~800-character window centered on the cited text — long text no longer requires scrolling to find the relevant span
  • Truncated context shows leading/trailing "…" indicators outside the markdown blocks for a cleaner read

Documents

  • Inserting a table is now a single click — the toolbar's table button drops a 3×3 grid with a header row in place rather than asking for a separate "New table" step
  • Deleting a table now opens an in-app confirmation dialog (with explicit messaging about undo) instead of relying on the browser's native confirm prompt
  • DOCX imports now preserve Word's text highlighting, mapping all 16 Word highlight colors to the nearest of Rhizar's 5 highlight colors so highlighted passages survive the round-trip
  • Submitting a document to the knowledge base now shows "Added to knowledge base" when it auto-ingests, or "Submitted to KB queue / Awaiting admin review" when admin approval is still needed, so submitters always know which state their document landed in

Knowledge Base

  • Knowledge base file processing has been rebuilt on a fault-tolerant event-driven pipeline — uploads now recover automatically from transient parser errors and rate limits instead of failing visibly
  • A background watcher scans every 10 minutes for files that got stuck mid-parse (e.g. a missed parser callback) and re-runs the next step, so files finish processing without anyone having to retry them
  • Per-agent and global limits on simultaneous parsing keep one large upload batch from blocking smaller uploads in the same workspace
  • Admins reviewing the KB Submissions section now see Approve and Decline buttons on every pending submission, including their own — the previous "Awaiting admin review" badge on self-submissions has been replaced with the standard action buttons

Chat Attachments

  • File attachments in chats (PDFs, Word docs, etc) now flow through the same robust extraction pipeline as knowledge base files, with the same automatic recovery from transient parser errors
  • A background watcher catches attachment extractions that fall behind and re-runs them, so attachments that previously appeared "stuck" in older builds now finish on their own

Admin Dashboard

  • The Top Expensive Turns drawer now includes an "Open in Langfuse" link that jumps straight to the full trace for that turn — span timing, nested tool calls, and prompt/response payloads are all one click away
  • The trace link in the drawer automatically points at the correct environment (production, staging, or development) so admins reviewing a turn never have to re-find it manually

AI Behavior

  • Every step of an assistant reply — knowledge base intent classification, query rewriting, the main response, each connected-agent consultation, and the post-turn chat summary — now reports under a single trace, making it possible to see the full decision path for any reply in one view

Feedback

  • The in-app feedback modal now works correctly when opened from admin pages (outside the workspace context), populating its workspace and agent dropdowns dynamically instead of appearing empty

  • Questions about what's in the knowledge base ("what files do you have?", "list your KB") are now answered directly from the system prompt without firing retrieval
  • Centralized effort tier policy: orchestrator chat runs at xhigh, consultation calls and background utilities at low, chat summary at medium — tunable in one place
  • Consultation prompt and orchestrator system prompt rewritten following Anthropic's prompt-engineering best practices for Opus 4.7 (positive examples, no length scaffolding, no caps-lock urgency)
  • Chat summary max output bumped from 300 → 500 tokens so longer chats summarize without truncation
