What

The session client gains ways to take, discard or adopt events that never reached the client, so a new connection can pick up where a closed one left off. Events marked ephemeral are always filtered out.

Details
  • New calls: take, discard and adopt undelivered client events.
  • The remote bridge now explicitly discards undelivered events when its v2 connection closes rather than dropping them silently.

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
