11 releases in June 2026.
What's new in OpenAI Codex CLI, June 2026
Codex CLI adds /import from Claude Code, session archive and delete, and /usage views
OpenAI Codex CLI in June 2026 added session management commands, a way to import from Claude Code, and account usage views. Eleven releases shipped, from rust-v0.136.0 to rust-v0.142.4.
Sessions can be archived with /archive or codex archive and codex unarchive, and permanently removed with codex delete or /delete. /import brings setup, project configuration and recent chats over from Claude Code, and typing @ opens a unified mentions menu for files, plugins and skills. /usage shows daily, weekly and cumulative token activity and can redeem usage-limit reset credits. /app hands the current thread off to Codex Desktop on macOS and Windows.
Other work covered plugins (codex plugin list --json, a reorganized /plugins menu), remote execution over encrypted Noise relay channels, MCP tool search by default, and opt-in Windows and macOS system proxy support. The last two patch releases (rust-v0.142.3 and rust-v0.142.4) had no user-facing changes.
