Codex spent the day correcting which side of a connection owns startup defaults, and shipped a recovery path for a Windows ACL file whose corruption used to halt deny-read reconciliation entirely.

Use server model defaults for connected TUI fresh starts openai/codex

by copyberry

Fresh starts against a local daemon or remote server now read server configuration before model bootstrap, so they no longer pick up stale client model settings; the change also unblocks startup when the model catalog is empty but managed new-thread defaults supply a model. Explicit model and reasoning-effort overrides still win.

Honor server reasoning summary defaults in new TUI threads openai/codex

by copyberry

Embedded and remote thread starts now share the same launch override handling, so server configuration and model defaults decide reasoning summaries instead of a client-side setting that previously forced summaries off whenever none was explicitly configured.

Recover malformed Windows deny-read ACL state safely openai/codex

by copyberry

Malformed deny_read_acl_state.json used to fail deny-read ACL reconciliation outright. Codex now retries the malformed read for up to two seconds, then rebuilds bookkeeping only after excluding active writers and applying current ACLs, preserving unknown historical denies and leaving linked file contents untouched.

Gate stable environment tool exposure behind a feature flag openai/codex

by copyberry

The default-off stable_environment_tools flag makes an experimental path opt-in: enabled, environment-backed tools are advertised before an executor is ready, selectors stay stable as readiness changes, and shell and login parameters are included. Execution still requires a usable environment and its policy.

v7.28.0 openai/openai-node

by openai-sdks[bot]

openai-node 7.28.0 landed with custom voice creation and agent session events in the API surface. The codex desk also added tools_change_count to turn profiles and analytics events, comparing the model-visible tool list before each sampling request and baselining on the first.
