v3.21.0

• Add support for public and private threads. Threads now have a visibility property that is "public" by default but can be set to "private" when created. Permissions can be used to decide which threads a user has access to, and threads can also be queried by their visibility to create filtered views.

• Add scoped comments permissions such as comments:public:write and comments:private:none.

• Breaking: Remove type and kind fields from HistoryVersion type. The backend no longer returns these.

• Add visibility to createThread.

• Support querying by visibility in getThreads.

• Add visibility to useCreateThread.

• Support querying by visibility in useThreads.

• Add useHistoryVersionYjsData() hook to retrieve raw Yjs binary data for a given version. Deprecate useHistoryVersionData() in its favor.

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
