• Rewrote workspace handling--windows can now appear on multiple workspaces, with each instance having different properties (position, size, whatever...)

  Create new window instances by using the copy-to-next-workspace, copy-to-previous-workspace, and copy-to-workspace:n commands. Merge instances by moving them to the same workspace, or using the delete-window-instance command

• Added linear-viewport commands--indexing two-dimensional virtual workspace areas by one-dimensional values (adapted from code by Eric Kidd)

• Rewrote tooltips; especially how they're removed (also, don't show null keymaps)

• Added new match-window property ungrouped. Means to put the window in a group on its own

• Translation additions/updates: da (Wandy Christiansen), en_GB (me), es (Iñaki García Etxebarria), fr (Christian Gillot), gl (Jesus Bravo Alvarez)

• Fixed bug of not refocusing unshaded windows

• Fixed bug of not notifying windows of their actual position after placing them

• Fixed bug when grabbing Hyper-modified buttons

• Fixed the focus-flickering when moving windows opaquely

• Fixed the commandp function when applied to autoload stubs

• Fixed typo in gnome-logout command (Jens Finke)

• Fixed raise-window-and-pass-through-click command to pass click2, etc, events through to frame parts

• Fixed infinite-regress bug when reading GNOME menu entries (`Type=directory', but actually a file)

• Fixed bug when showing window-move position with snapped movement (adapted from merlin@merlin.org)

• Fixed bug when matching null text properties
