The latest version of xscreensaver is always available on the web at http://www.jwz.org/xscreensaver/. ============ +Changes since 3.33: * Turned `memoryLimit' off by default, sigh. Apparently + some versions of the GL libraries (appear to) allocate + hundreds of megs for every GL program, so `memoryLimit' + was causing GL programs to malfunction or crash on + those systems. + * Improved fading on TrueColor XFree86 4.1.x systems. + * New GL hack, `circuit'. + * Added `fuzz' mode to `decayscreen'. + * New version of `whirlygig'. + * Added links to `glplanet' and `sphereEversion'. + * Fixed rare race condition that could make `sonar' hang. + * Fixed potential crash in `speedmine'. + * Made `xscreensaver-demo' not crash when imageDirectory + was set to a non-existent directory. + * Made `xscreensaver-getimage-video' invoke XawTV's + `streamer' program better. + * Made `phosphor' and `starwars' deal with CR, LF, + or CRLF line endings. + * Changes for Cygwin compilation environments. + * Made `sonar' compile on systems that can't ping. + * Configure changes for HPUX 10.20. + * Made PAM code work on Red Had 4.2 systems. + * Made `xscreensaver-command -deactivate' work when the + saver is not active: what that does is reset the idle + timer, as if keyboard input had been detected. This + was added for the benefit of people writing DVD-playing + software: they can now prevent the screensaver from + kicking in by sending a -deactivate message once a + minute while the movie is playing and not paused. + * Various minor portability tweaks. +Changes since 3.32: * New hacks, `speedmine' and `whirlygig'. + * Sped up `pyro', made the explosions look a bit better. + * Added better stars to `glplanet' and `starwars'. + * Many internal changes to `webcollage'. + * Some new options to `attraction'. + * Minor fix to `noseguy' to avoid un-erased pixels. + * Rewrote the screen-eraser effects so that they complete + in the same amount of time regardless of how slow + your X server is (some of them were glacial on servers + with slow blitting.) + * Fixed a potential free memory reference that could + sometimes cause a crash at startup. + * Possibly fixed a problem that could cause the daemon + to crash with an X error. I was never able to + reproduce this problem, but I think I might have + figured out what caused it. + * Worked around a problem that caused PAM authentication + to fail on some Red Hat 7.x systems. + * Added a `memoryLimit' parameter that controls the + amount of memory a graphics hack may allocate: if they + try to allocate more than this, malloc() will fail + (and they will exit or (safely) crash, rather than + hogging memory.) Default is 50M. + * Made `gnome-help-browser' be the default way to display + man pages in `xscreensaver-demo', if running on a + GNOME system. +Changes since 3.31: * The image-manipulating hacks (`slidescreen', etc.) can + now operate on randomly chosen image files from disk, + or on frames captured from the system's video input, + instead of (or in addition to) manipulating images of + the desktop. + * Rewrote `vidwhacker' to use the new image-grabbing + mechanism. + * Made fading work on TrueColor XFree86 4.x systems. + * Fixed a subtle rendering bug in `atlantis' (the fish + were inside out!) + * Made `atlantis' have a texture simulating light + reflections from the surface of the ocean. + * Fixed up label placement in `molecule'. + * Better color bars in `xteevee'. + * Made `install-strip' not try to strip scripts. +Changes since 3.30: * Put in more sensible defaults for DPMS, and updated + the documentation to reflect the fact that all your + DPMS settings are now belong to xscreensaver. + * Fixed the `xscreensaver.spec' file so that `--force' + is no longer needed. + * New versions of `rotzoomer' and `nerverot'. + * Fixed an OSF/1 compilation problem in `molecule'. +Changes since 3.29: * New hacks, `molecule' `dangerball', and `rotzoomer'. + * New version of `gflux'. + * Made `gltext' able to display the current time. + * Fixed a floating-point-precision problem in `gltext' + that sometimes caused horizontal lines to vanish. + * Removed the `-window-id' option from the hacks: + it never worked right, and was unnecessary. + * Made the `starwars' hack use thicker lines, antialias + the text, and fade out at the far edge instead of just + dropping off. + * Fixed an SHM segment leak in `moire'. +Changes since 3.28: * Better rendering of the new logo. + * New hack, `gltext'. + * Added `-planetary' option to `gears', to draw a + different kind of gear system. + * Made motion and rotation be smoother in `gears', + `glplanet', `moebius', `rubik', and `sierpinski3d'. + * Improved coloration in `sierpinski3d'. + * Made the GL hacks react to window size changes. + * Made most of the GL hacks take a -fps option (like + `pulsar' did), so you can use them to benchmark your + 3D hardware. + * Fixed the previous fix to `sonar'. + * Minor fix to `nerverot'. + Made sonar able to ping hosts on DEC OSF1. + * Eliminated a bogus "didn't get enough colors" warning + in some of the hacks. +Changes since 3.27: * New logo for xscreensaver! + * New hacks, `starwars' and `stonerview'. + * Made the motion of the bouncing ball in `stairs' be a + little less jerky. + * Made newly-added screenhacks be added to .xscreensaver + automatically: if there are hacks in the app-defaults + file that are not also in ~/.xscreensaver, they will + be added to the end of the list. + * Redid the `Screensaver Options' part of the control + panel; xscreensaver now lets you configure your DPMS + settings. + * Fixed some Makefile problems with non-GL builds. + * Fixed detection of MesaGL for version 3.3. + * Better workaround to Red Hat 7.0's broken gcc. + * Added Sparc Solaris kernel panic to `bsod'. +Changes since 3.26: * New hacks: `zoom' and `whirlwindwarp'. + * Fixed a free-memory-reference bug in `sonar'. + * Better error handling when there are no suitable GL + visuals. + * Added diagnostic dialog when xscreensaver-demo is + unable to launch xscreensaver (e.g., when running as + root.) + * Fixed a bug that caused screenhack argument changes + to be ignored when xscreensaver-demo was running as + root (if "root" and "nobody" have different home + directories.) + * Made the programs default to ":0" if $DISPLAY is unset. + * Made the `-verbose' output include information about + which server extensions were supported at compile time. + * Worked around Red Hat 7.0's broken gcc 2.96. + * Updated default delays on the GL hacks to look better + on machines with super-fast 3D hardware. + * Install `screensaver-properties-capplet' to work around + the usual egregious GNOME lossage. +Changes since 3.25: * Added "enabled" checkboxes in the list of hacks in + xscreensaver-demo (Gtk version only.) + * New hacks `hyperball', `xrayswarm', and `gflux'. + * New versions of `nerverot', `galaxy', and `hypercube'. + * Small fixes to `phosphor', `shadebobs', `xflame', + and `sonar'. + * Added external helper program `xscreensaver-gl-helper' + to figure out which X visual to use for OpenGL + programs. + * Configure updates for XFree86 4.0, and for BSD. + * Made it be more tolerant of bogus /etc/group files. + * When installing the PAM config file, first try to just + copy an existing "xdm" or "login" config file, so that + xscreensaver does authentication in the same way as the + rest of the system. +Changes since 3.24: * New hack, `nerverot'. + * Added BSD kernel panic to `bsod'. + * New version of `shadebobs'. + * New version of `petri'. + * Updated `webcollage' to handle recent Altavista URL + format changes; made it search the AP photo gallery. + * Revamped command-line options of `sonar' and made it + properly handle subnets. + * The `bubbles' hack can now trickle up or down the + screen. + * The `xsublim' hack can now read its text from programs. + * Support for GLE version 3 in `extrusion'. + * Fixed compilation problems in `maze'. + * Fixed a rare crash in `flow'. + * Fixes for minor installation problems. +Changes since 3.23: * Added `-ignorant' option to `maze' hack. + * Updates to `critical', `bsod', `xflame', and `flow'. + * Added support for Kerberos 5 (via its Kerberos 4 + compatibility layer.) + * Fixed a bad leak in `xteevee'. + * Updated `webcollage' to handle recent Altavista URL + format changes. + * Removed xscreensaver-demo's `Ok' and `Cancel' buttons, + since they were confusing people: all changes are now + instantanious. + * Made xscreensaver-demo install itself into the Gnome + Control Center. +Changes since 3.22: * Fixed some misplaced text fields in the Motif version + of xscreensaver-demo; fixed a crash in the Gtk version + that would happen if the programs list was empty. + * Fixed a recently-introduced bug in `pulsar'. + * Made `sierpinski3d' use solid tetrahedrons instead of + points. + * Added `-trace' option to `xmatrix'. + * Added new hacks `xteevee' and `xspirograph'. +Changes since 3.21: * Fixed some bugs in xscreensaver-demo. + * Rewrote the Motif version of xscreensaver-demo to + match the new Gtk version. + * The Athena toolkit is no longer supported. +Changes since 3.20: * Tweaked the xscreensaver-demo UI (Gtk only.) + * Fixed a few visual selection bugs. I think the proper + GL visual should be used with nVidia systems now. + * Made the Makefiles obey $install_prefix. + * Made the `xscreensaver.spec' file able to generate both + GL and non-GL packages simultaneously. +Changes since 3.19: * Added new hacks `ripples' and `sierpinski3d'. + * Made `xscreensaver-command -exit' be silent when no + screen saver was running (instead of complaining.) + * Made `webcollage' and `vidwhacker' use `xloadimage' + when available (in addition to `xli' and `xv'.) + * Improved memory usage in `petri' and gave it a hard + cap on how much memory it can allocate. + * Added `-watch' option to `xscreensaver-command'. + * Made `xscreensaver-demo' come up with the + most-recently-run hack selected by default. + * Rewrote the Gtk version of `xscreensaver-demo'. + It's a lot easier to use now. + * Extended the format of the programs list in the + .xscreensaver file, for the benefit of the new + capabilities of `xscreensaver-demo'. + NOTE: you might want to delete your ~/.xscreensaver + file and allow it to be re-created! The old one + should still work, but xscreensaver-demo won't be as + pretty. +Changes since 3.18: * Fixed gcc dependencies in `bumps' and `ccurve'. + * New hack, `extrusion'. + * Some of the web sites that `webcollage' was using as + its sources changed formats; tweaked it to understand + the current layouts. + * Added typeahead in the password dialog: if the screen + is locked, and you unlock it by typing a character, + that key will be automatically inserted in the + password dialog (unless it is Return, Enter, Space, + or a non-printing key like Shift.) + * Made `xmatrix' take a `-small' option, since some + folks with tiny screens prefer a smaller font. Changes since 3.17: * New versions of `shadebobs', `lmorph', and `distort'. * Added `ccurve', `blaster', and `bumps' hacks. * Replaced `forest' hack with a rewritten version.
