+## [2.8.3] — 2026-10-19
+
+### Changed
+
+- Windows Viewer: show the current Browse folder in a distinct, medium-weight header with a neutral background and thin separator above both list and grid views, with compact path text and keyboard-accessible full-path copying; keep parent and drive navigation unchanged. (#121)
+
+### Fixed
+
+- Windows Viewer: prepare directory listings before replacing Browse contents, preserving the previous folder, selection, scroll and image on access or device failures; explain explicit failures without repeated background-refresh dialogs and discard superseded navigation results. (#121)
