 # Changelog
 
-## Unreleased performance pass
+## v0.4.3 Alpha 1 (2026-07-26)
+
+* Copy and Move now work like a file-manager clipboard: select items, stage the
+  action, navigate to a destination, then choose **Paste Here**
+* Restored double-click folder opening while keeping single-click selection and
+  the explicit **Open** button
+* Fixed the upload drop area consuming the file-list height in short or empty
+  folders
+* Dragging files anywhere over the browser now reveals the upload state and
+  accepts the drop
+* Fixed virtual scrolling to listen to the actual file-list scroller
+* Reorganized file actions and disabled controls that do not apply to the
+  current selection
+* The clipboard panel now explains the workflow, shows staged items and the
+  current destination, and includes quick destination shortcuts
+* The three-column layout collapses earlier so the clipboard no longer gets
+  clipped on common laptop-sized browser windows
 
 * Large regular-file copies overlap sequential reads with one writer through
   two fixed 8 MiB, PS5-page-aligned slots; small files and initialization

 - Free space check before copy/move when size is known
 - Same-device, no-symlink recursive traversal with a 64-level depth cap and immediate abort on fatal storage/vnode errors
 - ShadowMountPlus warning before writes to its common scan roots
-- Folder size on click
+- Single-click selects; double-click opens folders; the Open button works with controllers
+- Folder size is calculated when a folder is selected
 
 **Selection**
 - Checkboxes + select all (works fine with a controller)

+# BFpilot v0.4.3 Alpha 1
+
+This alpha contains the work added after v0.4.0:
+
+- Separate Media tile installer, one `/data/BFpilot` data directory, and clean
+  reinjection/shutdown behavior
+- Payload loading through elfldr, chmod, case-insensitive paths, multi-select,
+  and RAR/7z/ZIP extraction
+- Safe text editing, recursive folder upload, conflict handling, staged
+  overwrite/merge, physical no-symlink traversal, and ShadowMountPlus warnings
+- Faster bounded large-file copies, writeback checkpoints, download tuning,
+  and earlier-return search queries with expanded telemetry
+- Clipboard-style Copy/Move/Paste, restored double-click folder opening,
+  selection-aware actions, fixed drag feedback, correct empty-folder sizing,
+  and responsive clipboard layout
+
+This still needs hardware testing for copy/move conflicts, large transfers,
+Rest Mode, and USB disconnect behavior before it should be considered stable.
