OpenAI AI Updates: May 27, 2026

1. Codex CLI 0.134.0 adds searchable conversation history, concurrent read-only MCP tools, and a primary —profile selector

OpenAI. OpenAI released Codex CLI 0.134.0 with searchable local conversation history featuring case-insensitive content matching and inline result previews, so engineers can find prior threads without leaving the terminal. The update promotes --profile to the primary profile selector across CLI, TUI permissions, and sandbox flows, rejecting legacy profile configurations with migration guidance. MCP setup gains per-server environment targeting and OAuth options for streamable HTTP servers, and read-only MCP tools can now run concurrently when they advertise the readOnlyHint. Bug fixes include websocket reconnection for remote reliability, Windows TUI rendering corrections, and preserved permission profile metadata during auto-review settings sync. Source
