New Features

• The /app command can now hand off the current CLI thread into Codex Desktop on macOS and native Windows, and Windows workspace launches can open directly into Desktop instead of stopping at a manual prompt. (#25638, #26500)
• Local image attachments and standalone image generations now expose their saved file paths to the model, which makes follow-up edits and file references more reliable. (#25944, #25947)
• Reasoning effort selection is more flexible: the TUI adds fallback shortcuts for terminals that miss Alt bindings, and model-defined effort levels now flow through in the order advertised by the model. (#25623, #26444, #26446)
• App-server integrations can now read account token usage, and Codex auth supports v2 personal access tokens in CLI and app-server flows. (#25344, #25731)
• Plugin automation got richer structured output: add/remove and marketplace commands support --json, plugin list JSON includes marketplace source, and plugin detail data now exposes default prompts, remote MCP servers, and unavailable app templates. (#26631, #26417, #25887, #26453, #26317)

Bug Fixes

• Goal workflows are more predictable: multiline paste in /goal edit no longer submits early, idle auto-turns stay out of Plan mode, and goals stop auto-continuing after terminal turn failures. (#26047, #26147, #26690)
• Forked threads now keep user-renamed titles instead of falling back to the original first-prompt name. (#26075)
• The TUI no longer adds extra blank space while streaming, and cancelled prompts reopen with the cursor at the end so you can keep editing naturally. (#26636, #26457)
• TUI config write failures now show the underlying cause, making validation problems and read-only filesystem issues much easier to diagnose. (#26537)
• Startup is more resilient across environments, with support for /usr/bin/bash, shorter Linux proxy socket paths, and pre-refresh of expired OAuth-backed MCP credentials. (#26538, #26553, #26482)
• Workspace instruction loading is more accurate for remote and symlinked workspaces, so the right AGENTS.md files are picked up consistently. (#26205, #26465)

Documentation

• The CLI README was refreshed to remove stale guidance and better match the current documentation flow. (#26313)

Chores

• TUI startup does less repeated plugin work by reusing discovery results and loading only hook metadata on the critical path. (#26469, #26272)
• resume --last now finds the newest matching session through the state DB first, which speeds up restore on large local histories. (#26462)
• Large MCP/Ollama streams and long message histories process much faster thanks to optimized byte scanning. (#26265)
