Polypane 24.1 introduces several new features for web developers. A new Measure overlay lets you drag a rectangle on the page to measure arbitrary areas and screenshot the selection. An XML/RSS Viewer (similar to the existing JSON viewer) supports tree view, filtering, syntax highlighting, and link recognition for inspecting RSS, OPML, and other XML files. The Find by CSS Selector tool now includes an inspect icon to open found elements directly in the elements panel. Additional improvements include double-click tab editing, per-tab ruler visibility, and an updated LinkedIn share preview in the Meta panel. Notable bug fixes address a Pointer Lock API crash, hover syncing failures, devtools panel resizing issues, and a startup crash on Windows ARM.
