Known breaks in Codex CLI from github.com/openai/codex, with quoted workarounds and fixed-in versions where they exist.
Type the version you're about to install (or just upgraded to). Lists tracked issues that mention it. Same data as /api/issues/codex.json.
Pulled from public GitHub issues updated in the last 45 days and filtered for always-on problems: install and update breakage, crashes and hangs, gateway/daemon trouble, auth, and headless setups. Ranked by engagement, weighted toward always-on, self-hosting, install/update, crash, auth, MCP and daemon problems (cosmetic desktop-UI issues are down-weighted). Workarounds and "fixed in" versions are quoted only when the issue or its top comments state them. Severity is an automatic estimate from labels, keywords, and engagement, not an official rating.
