Codex CLI 0.155.0-alpha.3 changelog - what changed

[new] codex mcp login accepts --no-browser to print the authorization URL and complete the OAuth callback without opening a browser (shell completions updated for bash, fish, and zsh).
[new] New exclude_slash_tmp configuration key.

Under the hood

MCP login/OAuth callback handling is split into dedicated CLI and client paths so the no-browser auth flow can collect the callback URL cleanly.
Config path-context support and expanded config-requirements modeling for stricter, more structured configuration checks.
Session plugin-selection support, plus realtime history presentation and TUI realtime settings work.
TUI turn-runtime and system-motion pieces for smoother session/turn handling in the interface.
Additional typed surfaces for remote-control pairing, workspace plugins, realtime voice listing, thread usage queries, and related thread/turn events.
