We've come a long way since 2.4.0 was released, and the end of the road is in sight for 2.5.0. 2.5.0_rc1 looks quite solid, and I'd like to get more people using it. This is the first pre-release of 2.5.0 that has been built for both Leopard and SnowLeopard. The Leopard version still installs to /usr/X11 and X11.app while the SL version installs to /opt/X11 and XQuartz.app to avoid the Software Update collisions that were so common in the Leopard days. With this release, I've created a separate Software Update feed that will contain beta versions (as well as final release versions). To switch to this feed rather than the final-release feed, please execute the following: SnowLeopard: defaults write org.macosforge.xquartz.X11 SUFeedURL http://static.macosforge.org/xquartz/downloads/sparkle/beta.xml Leopard: defaults write org.x.X11 SUFeedURL http://static.macosforge.org/xquartz/downloads/sparkle/beta.xml Assuming you have 2.4.0 on Leopard or one of the earlier 2.5.0 betas for SL, you should see an auto-update notification the next time you start X11 after running the above command. If you don't want to use the SU, you can just download the installer from these links: SnowLeopard: http://static.macosforge.org/xquartz/downloads/SL/XQuartz-2.5.0_rc1.dmg Leopard: http://static.macosforge.org/xquartz/downloads/Leopard/X11-2.5.0_rc1.dmg The full ChangeLog from 2.4.0 can be seen in the draft release notes: http://xquartz.macosforge.org/trac/wiki/X112.5.0 Please hammer this release. I feel confident that it is release quality, but I want to get a wider audience first. Thanks, Jeremy
