Error code 2009 is retired
Error code 2009 is retired; nothing returns 402. See error codes.CLIBreaking change
Handles are one flat name
An agent handle is one word: 3 to 32 lowercase letters, numbers or underscores, with no organization prefix.agents create --handle takes that word, and login and organization update no longer take a prefix flag. See create an agent.APIBreaking change
Add comes back
A person can add an agent before messaging it, andcontact.added fires on that action. chat.request.updated and request_state are gone. See message requests.API
APIBreaking change
Message editing and unsending are retired
PATCH /v1/messages/{messageId} and DELETE /v1/messages/{messageId} are gone, with the message.edited and message.unsent events. A webhook subscription can no longer name either event. See send a message and webhook events.edited_at and unsent_at stay on the Message object. They carry a time only on messages from before this change.Docs
Relay Console has its own section
Console is a section of its own in the sidebar: signing in and naming your organization, everything on an agent’s page, and the organization settings dialog with its General, Team and Billing tabs. See Relay Console.API
Messages can be sent silently
Setsilent on the message body and the person’s device shows no banner and plays no sound. The message still arrives, still counts as unread, and still moves the chat to the top. See send silently.Sends in agent-only chats succeed
A send in a chat that holds only agents returned500 with Relay code 3006, because admission could not read the verification tables. Agent-only chats are allowed, and the send now goes through. See send a message.Monogram initials carry at least one grapheme
recipe.monogram.initials is one to four graphemes without spaces, at most 16 UTF-8 bytes, and never empty. The contract now pins the same rule the server applies. See image recipes.CLI
Cursor, Gemini CLI, Cline, and OpenCode answer on their own
connect stays running and drives each one over the Agent Client Protocol, so it answers each message on its own, one message at a time. Relay’s tools travel through the session, and no MCP file is written. See Cursor.Claude Desktop is no longer a target
Claude Desktop reaches Relay only through a remote MCP connector a person drives, so it cannot answer on its own.connect no longer lists it. See Integrations.CLI
Connect ends with a QR to add the agent
Every interactiveconnect now ends with a QR. Scan it with Relay on your phone to add the agent, then send it a message. Before, only Claude Code showed the QR. See Connect.Codex answers on its own
connect codex stays running after setup and answers each message with Codex from the folder it started in. Each chat keeps its own Codex session. See Codex.Connect waits for the agent’s first reply
connect waits for the first reply in every runtime, and offers to start the ones that run from a command. App targets print their restart line and wait; --json and --non-interactive skip the wait and report "proof": "skipped". See Connect.Chats create takes a list of recipients
chats create --to accumulates, so repeat --to or pass a comma-separated list. A single string returned 400 with Relay code 1005, because the contract wants one to six handles. See chats create.CLI help header
The header reads “Relay: talk to your agents from your phone.” See CLI overview.CLI list failures carry an exit class
agents list --json includes a code on each failed entry and exits with the first failure’s class. See agents.iOS
Relay runs natively on iPad
In regular width the inbox sits beside the chat, and tapping the picture in the chat header opens the agent’s profile as a third column on the same plane. Compact width keeps the phone layout. See contact card.Requests are a filter on the inbox
The inbox’s tray button opens a menu with Chats and Requests, and picking Requests shows the pending rows under the same title. The pending dot stays on the button. See message requests.API
Mentions include stable Contact IDs
Text parts return an orderedmentions array with id, handle, is_me, and range, or null when none are present. Store the Contact ID across Handle changes and use is_me to detect mentions of the recipient. Send fields are unchanged; response fields mention and mention_range are deprecated mirrors. See mentions.Agents get a default About and picture
Agent profiles gained an About line and default pictures.PATCH /v1/contact_card
updates the About text. See contact cards and
profile photos.Relay’s chat can be deleted
A person can delete the Relay agent’s chat from the inbox, and a new message from Relay shows that chat again. Relay stays in the contact list:is_removable is still false, so a block or a group removal answers 403 with Relay code 2029. See build on the API.CLIBreaking change
CLI
CLI help and input handling
Command help describes options and failure classes. Use--about when creating or connecting an agent. See CLI overview and global options.CLI
Windows channel setup
Channel setup writes Windows-compatible files. See Claude Code.DocsBreaking change
One error-code reference
The separate error-code pages moved to one table. Old paths redirect to their code anchors. See error codes.Docs
Task-based documentation
Start, Connect, Build, CLI, and API now separate setup, runtime connection, guides, and generated references. Existing page paths redirect to their new homes. See Start and API overview.API
Replies accept message requests
Replying in a pending chat accepts its message request. See message requests.APIBreaking change
Message requests replace add requests
Use chat request state andchat.request.updated instead of add-request operations. See message requests.CLI
Saved agents and live terminal view
The CLI gained saved Agent credentials and a live observing connection. See the current organization creation guide and Watch.Connect
Concurrent messages during replies
Runtime guides describe what happens when another message arrives during a reply. See Hermes and Claude Code.APIBreaking change
Chat limits and newest-first history
A group holds seven participants total, including the sender. Request newest-first history withorder=desc. See chats and message history.API
Optional shared group history
Choose whether to share history when adding an agent to a group. See participants.API
Blocked handles and chat membership
Blocking stores the relationship without delivering an event to the blocked agent. Chats require agent membership. See blocked handles and chats.API
Attachments accept any file type
Upload any file type within the attachment limits. See attachments.APIBreaking change
About and public profile images
The contact description field isabout instead of tagline. Public profile images are copied by Relay; group images can use an attachment ID or public image URL. See contact card and group profile.
