+Changes since 5.01: * Reworked PAM code to support fingerprint readers, etc.
+ * Ported 'webcollage' to OSX.
+ * Added OSX 10.2 and 10.3 kernel panics to `bsod'.
+ * Fixed a Xinerama crash when changing the screen count.
+ * New blobbier `mirrorblob'.
+ * Minor updates to `lisa', `bsod', `ifs', `hypertorus',
+ `polytopes', `circuit', `endgame', `crackberg',
+ `flipflop', `flipscreen3d', `fliptext', and `carousel'.
+ * Enabled multi-threaded OpenGL on OSX.
+Changes since 5.00: * Backed out recent locale-related changes, since they
+ broke far more things than they fixed.
+ * Fail gracefully with ridiculously small window sizes.
+ * `xflame' and `flag' ignore bitmap option on MacOS.
+ * `speedmine' prefs work on MacOS.
+ * Better explosions in `boxed'.
+ * More dynamic motion in `sproingies'.
+ * More options in `flipflop'.
+ * Minor updates to `topblock'.

+Changes since 4.24: * Ported to MacOS X! (10.4.0 or newer)
+ * API change: instead of providing a single screenhack()
+ function that does not return, screen savers using the
+ screenhack.h framework must now provide "init" and
+ "draw one frame" functions instead. All bundled savers
+ have been updated; third-party patches will need work.
+ * All image-loading happens asynchronously.
+ * xscreensaver-getimage-file caches the contents of the
+ image directory for a few hours, so consecutive runs
+ won't have to re-list the whole directory tree.
+ * New hacks, `topblock' and `glschool'.
+ * Removed `xteevee' (superceded by `xanalogtv').
+ * Added variable-sized puzzle pieces to `jigsaw'.
+ * Changes to the defaults and command-line options of
+ many hacks to make the .xml files more consistent.
+ * Reap zombies in `glslideshow' and `carousel'.
+ * `sonar' works without setuid on OSX (dgram icmp).
+ * `xmatrix -mode pipe' displays the text of a subprocess.
+ * `endgame' has higher resolution chess-piece models.
+ * `webcollage' takes a -directory option to get images
+ from a local directory.
+ * The RPM spec file no longer auto-restarts xscreensaver
+ when a new version is installed. Restart it manually.
+Changes since 4.23: * New versions of `cube21', `glsnake', `celtic'.
+ * Backed out a DPMS-related patch that cause desktop
+ flickering with some X servers.
+ * Fixed startup crash in getgroups() when running setuid.
+ * Default to not displaying stderr on the saver window.
+ * Fixed bad free() in "Documentation" button.
+ * Don't try to run hacks that aren't installed.
+ * Minor fixes to various XML config files and man pages.
+Changes since 4.22: * New hacks, `glhanoi', `cube21', `timetunnel',
+ `juggler3d', and `celtic'.
+ * New versions of `tangram', `webcollage', `hypertorus',
+ `polytopes', and `ripples'.
+ * `sonar' is now quiet about unresolvable hosts.
+ * Minor corrections to BASIC code in `apple2'.
+ * xscreensaver-demo now provides an RPM clue when none
+ of the hacks seem to be installed.
+ * Don't install `ant' by default, since there is some
+ Java tool of that name, which was causing confusion.
+ And also it's boring.
+ * Made screen grabbing work again on MacOS 10.4.2.
+ * No longer prints bogus warnings about ClientMessages
+ intended for the window manager.
+ * Ignore unprintable characters in passwd entry field.
+ * Fixed yet another cross-host-display image-loading
+ endian problem.
+ * `xscreensaver-command -watch' and `-time' now work
+ on 64-bit machines.
