  ---------------------------------------------------------
** Version 4.8.0 **
  (see http://www.gnu.org/software/xboard/whats_new/4.8.0/ )

  * New features in this release
    * Resuming saved unfinished games
    * Setting up positions more easily
    * Bitbase adjudication
    * Showing tablebase hits
    * A new ICS window
    * Recalling board themes (XBoard)
    * Playing moves by clicking them
    * Fonts in the XBoard GTK build
    * Using the mousewheel (XBoard)
    * Displaying a blunder graph
    * Slicing up a PGN database
    * Auto-install of engines

  * New variant support
    * ASEAN Chess
    * Chu Shogi
    * Mighty Lion
    * Highlighting squares on engine command
    * Let the engine finish a user move
    * Non-standard variant names
    * Fischer castling in any variant
    * Knowing the moves of unknown pieces

  * Fixed bugs
    * Fix crash on using some Browse buttons in dialogs of the GTK
      build.
    * Fix buffer overflow in PGN parser, when all lines end in
      comments.
    * Fix crash on specifying non-existent board texture.
    * Prevent crash on double-click in XB Game List Tags dialog.
    * Fix the auto-display comment control in the General Options
      dialog of WinBoard, which was ignored.
    * Fix adjusting clocks by clicking them in Xaw build.
    * Fix zooming of Evaluation Graph XB with mousewheel, which was
      not working at all.
    * Fix sticky-windows feature WB for Windows 8, where it did not
      work at all.
    * WinBoard's seek graph is now sized to also cover any board rim.
    * Key bindings XB for non menu items are no longer ignored.
    * Set castling rights correctly after loading of game file from
      command line.
    * Allow castling and e.p. moves to be edited into opening book
      (and prevent their disappearance from it).
    * The sorting of engine output was made more robust against
      engines that send thinking output on fail lows.
    * Fix node-count display, which was clipped to 32 bits.
    * Suppress board-size oscillations in GTK build.
    * Fixed detection of screen size in GTK.  (This is a mixed
      blessing, as now it picks the largest possible window size, and
      in GTK interactive down-sizing is not possible.)
    * Fix mode highlighting after refusal of Two Machines mode because
      2nd engine did not support variant.
    * Blow up textures that are too small.
    * Ignore invalid color specs in stead of treating them as black
      (important because Cairo does not understand old xpm color
      names).
    * Prevent XB and WB from becoming unresponsive during lengthy
      tasks such as book building.
    * Fix slowdown of WB during loading of huge PGN files due to
      Game-List window update.
    * Limit width of menu bar for small board sizes in GTK build.
    * Improve the code to kill rogue engines in XB.
    * Drawing of pieces outside the board (in maximaized windows),
      which left lots of debris, is now suppressed.
    * Make WB window sizing handle multiple screens.
    * 50-move counter is no longer reset on Chess960 castlings.
    * Fix legality testing of A-side castling in FRC (which was
      allowed with Rook on a- and blocker on b-file).
    * Fixed piece ID of Falcon in Falcon Chess, which was written as
      '.' and could not be selected on promotion.
    * Fix cross-edge e.p. captures in Cylinder Chess (which was not
      recognized as e.p.).
    * Fix animation of Seirawan Chess castling + gating at Rook
      square, which made Rook disappear.
    * Fix adjudication of stalemates in variant Giveaway.
    * Display of the variant tag in the Game List now works.
    * Reset move entry (clearing target-square markers) on 'clear
      board' in Edit Position mode.
    * The Game List is automatically updated when you alter the tag
      selection for the game lines.
    * Indicate current variant in New Variant dialog of the GTK build
      (by printing it in boldface on the button).

  * Known Problems
    * GTK: in a tiling window manager the size of the board seems to be
      calculated incorrectly. A temporary fix for this is to use a fixed
      size by using the "-size <N>" and "-fixedSize true" options
      on the command line.
