Week 27

v3.21.0

All packages

• 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.

@liveblocks/client

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