Liveblocks dev server (v1.5.0)

• Add --random-port (-P) flag to liveblocks dev: bind a random free port instead of an explicit port number. With --cmd (-c), the chosen port is exposed to the command via LIVEBLOCKS_DEV_SERVER_PORT. Ideal for CI (no port collisions ever).
• Fix LiveList.push() so concurrent pushes from multiple clients no longer settle out of order.

v3.19.3

• Fix unexpected disconnects that could happen while receiving large or long-running streaming responses from the server (e.g. when loading a large initial storage state).

v3.19.2

Examples

• Added AI comments, buttons, and presence to Linear-like Issue Tracker. It can read and edit issue content and properties.
• Added AI comment pins to Collaborative Flowchart AI. It can read and edit flow state.

v3.19.0

• Add new markdownToCommentBody helper to convert Markdown strings into CommentBody objects.

• room.history.disable(fn) is now officially supported and no longer experimental. It allows running storage mutations without them appearing on the undo/redo stacks and it’s intended for background/async writes (e.g. writing back AI generation results) that should not be undoable.

• Fix keyboard shortcut in strikethrough tooltip. (Thanks @HellBoy-OP for the contribution!)

• Fix Yjs undo/redo silently breaking after editor.registerPlugin / unregisterPlugin is called (e.g. when Tiptap's BubbleMenu, DragHandle, or SlashCommand mount). The reattach restore() is now installed unconditionally on view destroy, matching upstream @tiptap/extension-collaboration. (Thanks @lucasmotta for the contribution!)

Liveblocks dev server (v1.4.1)

• Fix: client.getOrCreateRoom() no longer errors when the room already exists, matching production behavior.
• Fix: Yjs document updates made via PUT /v2/rooms/<roomId>/ydoc now get broadcast to connected WebSocket clients, matching production behavior.

v3.18.0

For full upgrade instructions, see the 3.18 upgrade guide.

• Breaking: useStorage now returns plain objects for LiveMap values instead of Map instances. Legacy APIs have been removed: .toImmutable(), .toObject(), .toArray().

• New .toJSON() on all Live structures, returning a cached JSON-compatible snapshot. JSON.stringify(root) now just works.

• New LiveObject.from(obj) to create a LiveObject from plain JSON, recursively converting nested objects/arrays to Live structures.

• New .reconcile(obj) to efficiently reconcile a LiveObject tree to match a JSON snapshot, only mutating what changed.

• initialStorage accepts LiveObject.from() result directly.

• New mutateFlow() API for reading and mutating React Flow data from a Node.js backend. Install via npm i @liveblocks/react-flow, import from @liveblocks/react-flow/node.

• Add standalone Avatar component to complement AvatarStack for more fine-grained customization.

• Add variant prop to AvatarStack to support outlined avatars.

• Fix: Initial storage seeding no longer creates an undo frame.

• Fix: Presence updates are now batched with storage updates.

Liveblocks dev server (v1.4.0)

• Add Feeds: room-scoped feeds with metadata and messages and APIs to list, create, update, and delete feeds and messages (fetchFeeds, fetchFeedMessages, addFeed, updateFeed, deleteFeed, addFeedMessage, updateFeedMessage, deleteFeedMessage).
