+Changes since 4.07: * New hacks, `atunnels' and `piecewise'.
+ * Physics improvement in `fluidballs'.
+ * Various fixes for XDarwin systems (X11 on MacOS X.)
+ * Added -clock option to `barcode'.
+ * Minor fixes to `endgame', `flurry', `flipscreen3d',
+ and `gflux'.
+Changes since 4.06: * New hacks, `flurry', `metaballs', `eruption',
+ `popsquares', and `barcode'.
+ * Minor updates to `maze' for high density mazes.
+ * Added double buffering to `fluidballs' and `whirlygig'.
+ * Bug fixes for running xscreensaver to a remote XFree86
+ display (which nobody would ever do...)
+ * Updated `webcollage' (faster Alta Vista searching.)
+ * Updated `glplanet' so the sun sets in the west.
+ * Updated `sproingies' with smooth, unsegmented surfaces.
+ * Fixed Perl version-sensitivity in
+ `xscreensaver-getimage-file'.
+ * Fixed GTK2 scrolling bug in `xscreensaver-demo'.
+Changes since 4.05: * New hack, `glblur' (disabled by default, since it
+ requires fast OpenGL texture support.)
+ * New hack, `halftone'.
+ * Updates to `endgame', `queens', `bumps', `glplanet',
+ `engine', and `circuit'.
+ * New version of `menger' that uses far fewer polygons.
+ * Fixed minor bug in `critical' that could cause some
+ bogus X servers to crash.
+ * Better labels in `molecule': the labels now appear to
+ be attached to the atoms, instead of floating in front
+ of the whole scene.
+ * Fixed bug that could rarely cause GL hacks to fail to
+ double-buffer (causing intermittent flickering.)
+ * Fixed a relative-URL-parsing bug in `webcollage'.
+ * Fixed a bug that (sometimes) caused the window manager
+ close box to kill `xscreensaver-demo' with a crash
+ instead of a graceful exit.
+ * Updated xscreensaver.pam to the Red Hat 7.3 way.
+ * More Gnome2-related configure crap.
+ * Updated to latest `config.guess' and `config.sub'.
+ * Fixed occasional core dump in `distort'.
+ * Added a Linux fsck failure and kernel panic to `bsod'.
+ * Added MacOS X kernel panic to `bsod'.
+ * Fixed a bug in `bsod' (all bsod bugs are ironic.)
+ * Fixed a bug that caused `xscreensaver-gl-helper' to
+ print a nonsense visual ID with some versions of
+ `printf': this could cause GL programs to display
+ incorrectly (e.g., flickery.)
+Changes since 4.04: * More `configure' tweaks to try and get things working
+ on systems that both Gtk 1.x and 2.x installed.
+ * New hack, `endgame'.
+ * Minor updates to `gltext'.
