Codex CLI 0.145.0-alpha.4 changelog - what changed

[new] Amazon Bedrock is available as a login account option.
[new] Scheduled tasks support additional schedule kinds: hourly, daily, weekdays, and weekly.
[new] Tool approval handling includes a dedicated approvals path, including patch approval responses and network permission modeling.
[changed] Turn completion and turn abort events carry additional structured fields.
[changed] Plugin detail and remote plugin release payloads were updated (including marketplace source handling).
[removed] The personality migration path has been dropped.
[removed] Legacy client relay events (Ack / ClientMessage and related variants) are no longer part of the event set.

Under the hood

MCP OAuth refresh is more robust, with explicit refresh locking and transactional refresh handling so concurrent refreshes do not race.
Rollout reading gained a reverse JSONL scanner for scanning session history from the end of a log.
Exec-server noise relay work continues: message framing was added, and the previous relay protobuf surface was removed.
The exec JSONL event-processor path was removed in favor of the current event pipeline.
Config and model info shapes were tightened slightly (field-level adjustments on core config/model types).
Additional failure signaling covers denied MITM hook cases.
Dependency and version metadata were bumped for the alpha.4 tag.

If you still depended on automatic personality migration from older configs, re-check personality-related settings after upgrading—that migration path is gone.
Alpha builds may still change event and plugin payload shapes; pin integrations that parse those structures carefully.
