What
Print mode is the non-interactive way of running Claude Code with claude -p, where it answers and exits instead of opening a chat screen. Several of its outputs change:
Text results can now be printed as each turn ends, not only when Claude Code exits. Empty successful results are skipped, and several results are separated by blank lines. This is controlled by the gate tengu_jazzy_puddle; nothing has been read about its state.
When input is closed and Claude Code keeps waiting on background tasks or a scheduled wakeup, it now prints a one-time notice saying what it is waiting for (Waiting for background work to finish). It goes to stderr (the error output) or the debug log.
The content_block_stop, message_delta and message_stop events in the live SDK stream (the event feed a program reads when driving Claude Code from code) are now built with extra context added into them.
Why
Headless runs that looked stuck now say why they are waiting. Scripts that run several turns may now see intermediate results printed, and programs that read stream events may see extra fields on those three events.

Nothing here resolved what this flag was doing on this version, so nothing here should be read as on or off.

These values were read against a different version of Claude Code, so treat them as the nearest reading available instead of one taken on this release.

Anthropic's release notes agreeAdded a line on stderr, when it is a terminal, that says what a claude -p run is waiting for when it stays open after its last turn
