Chrome 138 DevTools introduces significant improvements across multiple panels. The Performance panel now shows preconnected origins, server response times, and redirects while reducing noise from V8 compile events. The Elements panel enhances CSS debugging with tooltips showing full variable definition chains and step-by-step calculations for complex values, plus adds @function support. The Network panel adds a has-request-header filter and Direct Sockets monitoring for Isolated Web Apps. The Sensors panel now supports geolocation accuracy emulation. Additional improvements include accessibility enhancements, deprecated Web SQL removal, and various UI refinements across panels.
