What's New

v1.16.20 adds Codex session management and JSON output improvements.

New Features

Added `claude_session_id` and `claude_turn_uuid` to JSON receipts.
Added `session send --json` and `session send-status --json` for Claude sessions.
Added long follow-up support for Claude sessions.

Improvements

Enhanced JSON output for receipts with correlation IDs.
Improved Codex session isolation and output binding.
`session send --wait` now respects caller timeout instead of internal limit.

Bug Fixes

Fixed Codex child sessions to no longer bind sibling rollouts.
Fixed Codex identity persistence at launch, output, stop, and archive.
Fixed `session send --wait` timeout behavior for long turns.
Fixed profile-scoped Codex configuration directory recall.

Upgrade Notes

No configuration changes are required. Note that JSON receipts for Claude sessions now include `claude_session_id` and `claude_turn_uuid` fields, which may affect consumers of the JSON output.
