Codex CLI 0.156.0 introduces new features like a fullscreen UI and voice conversations, along with several bug fixes.

Why it matters: Users who rely on Codex CLI for development will benefit from enhanced usability and new features.

Choose an optional fullscreen UI with /tui for your next launch, including transcript search, mouse selection, and right-click copying.
Voice conversations are enabled by default, with an F8 toggle, a /voice settings picker, and bundled audio runtimes for Linux and Windows.
Explore account usage, token totals, and plugin and skill activity through the /usage analytics dashboard.
Filter tasks by status and create worktree sessions from the agent command center; worktree support is now enabled by default.
Customize the terminal with six new themes and view supported Mermaid diagrams and display equations directly in responses.
Update the local background server through /daemon, or bypass it with --no-daemon.

Preserve streamed answers and plans when turns fail, are interrupted, or receive subagent completion events.
Fix clipboard forwarding in tmux and SSH sessions and preserve tab indentation when terminals send pasted text as individual keystrokes.
Restore Plan mode when resuming sessions and preserve thread identity and settings when editing earlier prompts.
Recover login through system proxies and refresh MCP credentials when OAuth discovery returns a 503 error.
Prevent speech from being dropped during playback pauses or bursts of incoming audio.
Close sandbox isolation gaps involving inbound Windows connections, privileged Linux/macOS sockets, and writes through read-only macOS file handles.

Clarify that deprecated friendly and pragmatic personality settings no longer select response styles.
Explain how ? matches a single character in network proxy allow and deny patterns.
