It's been about 2 months since the last release (2.3.3.2), and I hope it has been worth the wait. 2.4.0 is finally ready to enter rc status. I'm fairly confident that it is in a production-ready state, but I want a wider audience to begin using it for the next week or so before I give it the gold stamp. 2.4.0 introduces a bunch of fixes and feature requests that have been pending for a while including: * Automatic updates * linking issues with libOSMesa * fork()ing issues with libfreetype * Auto-quit support via quartz-wm * misc Xorg packages updated to the latest releases * Stabilization of and transition to the 1.5.x server branch (which includes improved AIGLX support). http://static.macosforge.org/xquartz/downloads/X11-2.4.0_rc1.dmg A more detailed ChangeLog is here: http://xquartz.macosforge.org/trac/wiki/X112.4.0 === Testing Automatic Updates === This past week, beta users were testing the automatic updates feature in X11, and I think all the kinks have been worked out. If you'd like to test the automatic updates, you can do so by "tricking" X11 into thinking it's outdated. To do so, edit /Applications/Utilities/ X11.app/Contents/Info.plist and change CFBundleVersion to a lover value (like 2.4.0). When you restart X11, you can goto "X11->Check for Updates..." and you should be able to "update" to the newer version. === Known Issues === The automatic updates don't give you an "Are you sure you want to quit?" dialog before restarting. This is fixed in git already. Thanks, Jeremy
