Release Notes

New Features - Introducing GPT-5.3-Codex. Learn More - Steer mode is now stable and enabled by default, so Enter sends immediately during running tasks while Tab explicitly queues follow-up input. (10690) Bug Fixes - Fixed resumeThread() argument ordering in the TypeScript SDK so resuming with local images no longer starts an unintended new session. (10709) - Fixed model-instruction handling when changing models mid-conversation or resuming with a different model, ensuring the correct developer instructions are applied. (10651, 10719) - Fixed a remote compaction mismatch where token pre-estimation and compact payload generation could use different base instructions, improving trim accuracy and avoiding context overflows. (10692) - Cloud requirements now reload immediately after login instead of requiring a later refresh path to take effect. (10725) Chores - Restored the default assistant personality to Pragmatic across config and related tests/UI snapshots. (10705) - Unified collaboration mode naming and metadata across prompts, tools, protocol types, and TUI labels for more consistent mode behavior and messaging.
