[Xquartz-dev] XQuartz 2.7.10_rc1

[Jeremy Huddleston Sequoia]

I built 2.7.10_rc1 against the 10.12 SDK.  This has introduced some compatibility issues when running on older OS versions.  I'm going to rebuild an rc2 against the 10.11 SDK and aim to have it available tomorrow.

In the mean time, please go back to 2.7.10_beta2 if you have issues.

See: https://bugs.freedesktop.org/show_bug.cgi?id=97757

Thanks,
Jeremy

Because of issues with applications that use both Motif and libXaw, I've abandoned the previous approach of shipping /opt/X11/lib/libXt.6.dylib as flat_namespace and /opt/X11/lib/libXt.7.dylib as the two-level namespace version.  Now, /opt/X11/lib/libXt.6.dylib is two-level namespace, and /opt/X11/lib/libXt.7.dylib is provided as a symlink to it for compatibility.  This means that Motif based applications will fail to launch by default unless this bug is fixed in Motif.
