+Changes since 4.20: * New hack: `fliptext'.
+ * Changed default configure installation directories:
+ /usr/bin/ for xscreensaver, etc.;
+ /usr/libexec/xscreensaver/ for hacks;
+ /usr/share/xscreensaver/config/ for xml files.
+ * All the text-manipulating screen savers can have their
+ text source configured via `xscreensaver-demo' now.
+ * xscreensaver.spec now builds three RPMs:
+ base (no hacks); extras (2d hacks); and gl-extras.
+ * Added `-program' and `-front' option to `gltext'.
+ * Added `-shells' to `molecule'.
+ * Fixed text-alpha glitch in `carousel'.
+ * New `pacman': the ghosts can be killed now.
+ * Fixed a bug in screen-grabbing GL hacks where images
+ would be tiled instead of scaled on machines that
+ can't do large textures.
+ * `webcollage' can hit Flickr now.
+ * New (rewritten) implementation of `ifs'.
+ * The unlock dialog can be made to have a "New Login"
+ button that will run `gdmflexiserver'. Experimental!
+ * Fixed non-ASCII display bug in `starwars'.
+ * Configure finds a default for imageDirectory.
+ * "xscreensaver-command -lock" now works even if
+ in "screensaver disabled" mode.
+ * If a bad password is typed while CapsLock is on, the
+ unlock dialog says "CapsLock?" instead of "Sorry".
+ * Mouse motion only counts as activity if the mouse moved
+ more than 10 pixels (so the screen won't unblank every
+ time you bump your desk.)
+ * New mode option "random-same": if you have multiple
+ monitors, this will run the *same* randomly chosen
+ hack on each screen, instead of different ones on each.
+Changes since 4.19: * New hacks, `fiberlamp', `boing', `boxfit', and
+ `carousel'.
+ * Rewrote `glslideshow' again: should be faster now.
+ * Sped up loading of images in GL programs.
+ * `starwars' uses texture-mapped fonts now.
+ * New `bsod' modes: tru64, hppa, and nvidia.
+ * Updates to `webcollage', `juggle', `pinion',
+ `fireworkx', `sonar', `extrusion', `substrate', and
+ `pong'.
+Changes since 4.18: * New hacks, `substrate', `intermomentary', `fireworkx',
+ and `pinion'.
+ * New version of `flow'.
+ * Made /proc/interrupts work again on Linux 2.6.
+ * Made `analogtv' not hog the CPU.
+ * Made analogtv-based hacks work properly on PPC/ARM.
+ * Fixed a bad memory leak in `piecewise'.
+ * Minor updates to `sonar', `molecule', `glmatrix',
+ `galaxy', and `webcollage'.
+ * Removed support for GTK 1.x (everyone uses 2.x now.)
