 # Changelog
 
+## 2026-01-28 - 1.9.0 - feat(s3-columns)
+load full prefix path on initial load and add folder upload support
+
+- loadInitialColumn now loads all prefix path segments in parallel and pre-selects child prefixes so multi-column path is restored
+- added getPathSegments helper and auto-scroll to show the rightmost column after load
+- added separate hidden folder input (webkitdirectory) and folder upload flow; triggerFileUpload now accepts 'files' | 'folder'
+- replaced generic 'Upload...' with 'Upload Files...' and added 'Upload Folder...' menu items
+- updated updated() to react to currentPrefix changes and cleaned up folder input on disconnectedCallback
+
 ## 2026-01-28 - 1.8.1 - fix(cli)
 set executable permission on cli.js
