v1.3.0

• #322 — Add Presence functionality (@gkubisa, @curran, @alecgibson)
  • Warning - This current presence implementation may not scale to hundreds of subscribed clients on a given doc, as a new client subscribing to presence for a doc will request presence data from all other clients subscribed to presence on that doc.
  • To enable presence handling for a server, pass options.presence: true to the ShareDB Backend constructor.
  • See README
  • Also see the presence example
