Codex CLI 0.158.0 released

#What changed

#New Features

• Configure copy-on-select and right-click paste in the fullscreen TUI. Copied transcript selections now preserve Markdown formatting. (#47639, #47896, #48118)
• Connect to MCP servers that require pre-registered OAuth client secrets, including through codex mcp add --oauth-client-secret. (#47891)
• Secure direct exec-server WebSocket connections with bearer tokens, including connections configured through app-server. (#47601, #47648)
• Image generation and editing can explicitly request transparent backgrounds, and edits now accept file-backed conversation images. (#47484, #47956)
• Terminal input approval is enabled by default for commands running with elevated permissions; runtime-only grants no longer cause unnecessary reviews. (#47799, #48073)

#Bug Fixes

• Fixed Windows sandbox failures involving ordinary Windows 10 paths, rejected stored credentials, and large permission policies. (#47672, #47695, #47919)
• Fixed Linux sandbox startup with nested writable roots and preserved Git metadata protections across writable roots on Linux and macOS. (#47623, #47974)
• macOS patch operations now recognize system path aliases covered by existing permissions, avoiding unnecessary approval prompts. (#47879)
• Approval reviews now retry when new user input arrives, so a status question does not automatically abort a pending action. (#47819)
• Mermaid flowcharts now render quoted labels and ampersands; unsupported diagrams explain why they fall back to source. (#47572, #47678)
• Command completion events now include early output and report process-launch failures to clients. (#47529, #47665)
