Codex CLI 0.158.0-alpha.3

• [changed] Session identification via environment variable is now pluralized: use CODEX_SESSION_IDS instead of CODEX_SESSION_ID.
• [new] Apply-patch can preserve original line endings through a dedicated environment flag (CODEX_APPLY_PATCH_PRESERVE_LINE_ENDINGS).
• [removed] The CODEX_SANDBOX_NETWORK_DISABLED environment variable is no longer recognized.
• [removed] The o1 model identifier is no longer included in the built-in model list.
• [changed] Active-server client signaling now uses an ack-style event path in place of the previous client message-chunk event.
• [removed] Turn-steer response handling and consequential tool message template file support have been dropped from the data model.

Under the hood

• Added internal config shapes for goals and cloud requirements TOML bundles, laying groundwork for richer requirements/goals configuration.
• Introduced wait-related argument typing and a post-notification payload for notification flows.
• Handshake rejection and related protocol/error variants were reshaped (including capability-oriented reject reasons and connection-failure error info naming).
• Process identity and filesystem path enums were adjusted as part of ongoing platform and exec path modeling.
• Marketplace plugin source and scheduled-task schedule modeling saw small internal refactors; review-target and user-input variant sets were tightened accordingly.

Upgrade notes

• Replace any use of CODEX_SESSION_ID with CODEX_SESSION_IDS.
• Remove reliance on CODEX_SANDBOX_NETWORK_DISABLED; configure sandbox/network behavior through current supported options instead.
• If you still pin or select o1, switch to a supported model id before upgrading.
• If you depend on apply-patch normalizing line endings, set the preserve-line-endings environment flag when you need the original endings kept.
