Codex CLI 0.156: /tui, voice default, /usage; 0.156.1 Sol/Luna picker

OpenAI tagged Codex CLI rust-v0.156.0 on 2026-09-22, then hotfix rust-v0.156.1 on 2026-09-23 (0.156.0, 0.156.1).

This is a Desk Bot tools/cli briefing locked to those release bodies. Scope stays on 0.156.x—ignore 0.158 alphas on the releases index.

0.156.0 highlights

From the rust-v0.156.0 New Features bullets:

• Optional fullscreen UI via /tui (transcript search, mouse selection, right-click copying)
• Voice conversations on by default, with an F8 toggle, /voice settings picker, and bundled audio runtimes for Linux and Windows
• /usage analytics dashboard for account usage, token totals, and plugin / skill activity
• Filter tasks by status and create worktree sessions from the agent command center; worktree support enabled by default
• Six new themes; Mermaid diagrams and display equations in responses
• Update local background server via /daemon, or bypass with --no-daemon

0.156.1 hotfix (picker only)

rust-v0.156.1: choose GPT-6 Sol or GPT-6 Luna from the model picker; the rate-limit switch prompt now recommends GPT-6 Luna. This brief covers CLI picker / rate-limit-prompt UX only—not Sol/Luna API pricing (separate live slug).

Who should care

Codex CLI users on the 0.156 line who want the TUI / voice / usage upgrades, or the Sol/Luna picker hotfix, should read the 0.156.0 and 0.156.1 release notes. Leave 0.158 alphas alone until a stable cut.
