Codex 0.153.0 ships; Claude Code latest is 2.1.259 with managed MCP and headless deny.

openai/codex rust-v0.153.0: Vim undo/redo that keeps pastes and attachments, plugin CLI for remote marketplaces, optional tui.auto_recap = false, fuller TUI history, earlier half-allowance warning for Plus/Team in the ~5h window, and TUI reconnect after app-server drops without losing drafts.¹

claude-code v2.1.259 adds managedMcpServers (org HTTP/SSE MCP for every user; command-shaped entries skipped) and --permission-prompts none for unattended hosts. Concurrent sessions no longer clobber ~/.claude.json; Bash Read deny rules cover option values and cd && cat compounds. npm: stable 2.1.236 / latest 2.1.259.²³
