• New option to only highlight frame parts when their window is focused (highlight-when-unfocused)

• Typing ESC while moving/resizing a window cancels the operation, restoring the original geometry

• New session management hook sm-after-restore-hook

• New function set-frame-part-value---makes customizing the frame-part-classes variables easier

• Support for loading themes from tar files; needs librep 0.7

• Fix bug when allocating colors (choosing an incorrect cached color)

• Fix image tiling in frame part backgrounds

• Handle shifted keysyms when passive grabbing

• Fix another race condition when active grabbing

• Fix _WIN_CLIENT_LIST property not being set properly (both missing windows immediately after they're adopted, and of intentionally skipping ignored windows)

• Fix some problems with viewports when exiting/restarting

• Fix broken stacking of windows after they're mapped

• Prevent smart window placement blowing up when large numbers of windows are open/opened (throttle back to random placement when the event queue is too large, as well as trying to prune the search space)
