Resuming a remote session can check subagent transcripts and load them later

When Claude Code rebuilds a remote session so you can carry on with it, it can now be told to verify the transcripts of subagents. A subagent is a helper Claude starts to work on part of a task, and its transcript is the record of what it did. With that option set, subagent history is loaded lazily, meaning only when it is needed rather than all at once.

The usage report sent when the rebuild finishes can now also include hashed, scrambled forms of the project folder, the local session id, and the folder and session that were behind the latest point of the session.
