Codex CLI 0.146.0-alpha.12

• [removed] The CODEX_SANDBOX_NETWORK_DISABLED environment variable is no longer supported.
• [changed] Remote network proxy configuration was reshaped (launch and runtime settings updated together).
• [new] Exec/server network policy requests are modeled end-to-end so sandbox networking can be decided through the policy path rather than a blunt env kill-switch.
• [changed] ItemCompleted carries a slightly richer payload than before.
• [changed] User audio input handling was unified under a single audio input variant (replacing the older local-audio form).
• [new] Collaboration sessions emit a waiting-end event when a wait completes.
• [new] Denied MITM/hook failures surface as their own failure signal.

Under the hood

• TUI chat turns pick up a dedicated turn-runtime module for clearer session/turn lifecycle handling.
• Additional typed payloads land for HTTP request body deltas, secrets requests, personality snapshots, GitHub pull-request API items, and related release-info metadata.
• OpenTelemetry exporter wiring favors OTLP/HTTP over the previous OTLP/gRPC path; thread-store and sandbox-policy deserialization enums were tightened in the same pass.
• Web-search action and scheduled-task schedule variants were adjusted (including weekday schedules in place of the older hourly form).
• New color_quant dependency for image color quantization support.
