• Deprecate session.FULL_ACCESS and session.READ_ACCESS in favor of ["*:write"] and ["*:read"] respectively.

• Deprecate room.getStorageSnapshot() in favor of room.getStorageOrNull().

Examples

v3.19.5

• Fix a LiveList divergence after reconnects: a pending push could under specific timing conditions during a reconnect still cause a divergence between clients, despite the fix from 3.19.4.

Liveblocks dev server (v1.6.1)

• Fix a LiveList divergence after reconnects: when a client re-sends a pending push op whose node the server had already stored (the original ack got lost in the disconnect)

v3.19.4

• Fix LiveList.push() so concurrent pushes from multiple clients no longer settle out of order.
• Fix a bug where a LiveObject key deleted while a client was offline would reappear on reconnect, preventing the two clients from reconverging.
• Fix a bug where reconnecting would emit too many update notifications for LiveObject keys whose values had not actually changed.
• Fix a bug where deleting a nested live value from a LiveObject omitted the removed value (deletedItem) from the change notification.

Examples

• New example: Collaborative SuperDoc editor.

• Fix LiveList.push() so concurrent pushes from multiple clients no longer settle out of order.

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.
