Woofun AI reports that OpenAI has released a Codex update addressing long conversation navigation and UI scaling issues. The new navigation rail allows users to preview and jump to nearby conversation turns, while thread scrolling now maintains browsing position during switches.

The update includes alignment protection for tooltips, menus, and dialogs during scaling, alongside expanded search controls and synchronized unread badges. Performance improvements reduce background workload for thread switches, and copying text to Slack now retains Markdown formatting.
