OpenAI
OpenAI's Codex released rust-v0.156.0 on Sep 22 with an optional fullscreen UI via /tui (transcript search, mouse selection), voice conversations enabled by default (F8 toggle), a /usage analytics dashboard, worktree sessions by default, and Mermaid/equation inline rendering. The release also closed sandbox isolation gaps on Windows inbound connections and privileged Linux/macOS sockets, and bundled OpenSSL 3.6.4. Alpha train 0.157.0-alpha.2 through alpha.10 landed across Sep 21-22.
Why it matters
Fullscreen transcript search and per-skill usage analytics make Codex noticeably more usable as a daily-driver terminal agent.
