Codex CLI 0.155.0-alpha.16 changelog - what changed

[new] --no-daemon — Run Codex without the shared background server, even when one is already running. Supported on the main CLI and on resume / fork. The agents overview still needs the shared server, so the flag is rejected there.
[changed] Shell completions — bash, fish, and zsh completions include --no-daemon and its help text for the relevant commands.
[removed] exclude_slash_tmp config key — This configuration option is no longer recognized.

Under the hood

Realtime history presentation work in core for how session history is shaped for display.
Chat composer updates in the TUI, including new sparkle field support in the bottom pane.
TUI chat keymap model expanded; several internal config and payload types (analytics, context management, goals, profile invocation, and related snapshots) were reshaped.
Client messaging and error/event paths adjusted (including TUI suspend-failure handling), along with routine dependency lockfile churn.
