Codex CLI 0.156.0-alpha.7 changelog - what changed

[new] codex doctor accepts --probe-filesystem-path for an isolated filesystem probe that exits before configuration is loaded (shell completions updated for bash, fish, and zsh).
[new] Config key exclude_slash_tmp for controlling whether slash/temp path handling excludes /tmp.
[removed] The o1 model identifier is no longer included in the built-in model list.
[changed] Shell completion scripts refreshed for the current CLI surface.

Under the hood

Plugin/executor wiring was reworked (plugin_app / executor provider paths) in place of the previous connector plugin provider layout.
Model-provider workspace routing support landed for directing work across workspace context.
App-server daemon launch and TUI daemon startup paths were extended for cleaner daemon bring-up.
Session guardian checkpoints and shared thread instructions improve session continuity and instruction reuse across threads.
Agent completion control and exec-server relay protocol pieces advanced the control/relay plane between components.
Filesystem sandbox and related config/requirements shapes were tightened (including Windows and broader config TOML requirements).
Plugin detail/release payloads and several app-server request/response types were adjusted as the plugins and remote-control surfaces evolve.
Dependency cleanup: dropped the headers crate.
