Codex CLI 0.111.0: Fast Mode Default, MCP Elicitation

Fast mode is now default in Codex CLI 0.111.0. Plus: local ESM imports in js_repl, better plugin discovery, and structured MCP elicitation in app-server v2.

TL;DR

Fast mode is now the default; TUI header shows which mode you're running
js_repl can now dynamically import local .js and .mjs files from your workspace
Codex tells the model which plugins are enabled at session start for better MCP discovery
App-server v2 exposes MCP elicitation as structured request/response instead of raw events
Thread resume now preserves git context and keeps apps enabled

New

Fast mode default — Fast mode is now enabled by default, and the TUI header displays whether your session is running in Fast or Standard mode.
Local ESM imports in js_repl — The js_repl can now dynamically import local .js and .mjs files, making it easier to reuse workspace scripts directly from the REPL.
Plugin discovery at session start — Codex now tells the model which plugins are enabled when a session starts, improving discovery of installed MCPs, apps, and skills.
MCP elicitation as structured API — App-server v2 now exposes MCP elicitation as a structured request/response flow instead of raw events, simplifying client integrations.
Expanded image workflow support — Clients can now handle image-generation events client-side and access model metadata for image-capable web search.

Fixed

Thread resume state preservation — Resuming a thread now preserves its stored git context and keeps apps enabled, avoiding broken state after codex resume.
