These packages were built with libjpeg-turbo 1.1.1:

Package signatures

To ensure the integrity of the VirtualGL binary packages, the RPM and DEB files and the source tarball are signed using the following key:
http://www.VirtualGL.org/key/VGL-GPG-KEY-1024
http://pgp.mit.edu/pks/lookup?op=get&search=0x6BBEFA1972FEB9CE
and the Windows installers are signed using a code signing certificate.

2.3

Significant changes relative to 2.3 beta1:

1. Fixed a regression whereby GLXSpheres would ignore the first argument after -fs.

2. glXChooseFBConfig() and glXChooseFBConfigSGIX() were erroneously returning an error when a NULL attribute list pointer was passed to them. They now behave correctly.

3. Fixed a regression whereby VirtualGL would deadlock when using the X11 Transport with a remote X connection.

4. Fixed a GL_INVALID_OPERATION error that would occur after a call to glXSwapBuffers(), when a context with the OpenGL Core Profile was being used.

5. Fixed an issue whereby VirtualGL, when compiled with GCC 4.6, would abort with terminate called after throwing an instance of 'rrerror' whenever a 3D application running in VirtualGL exited.

6. Added a new configuration option (VGL_DEFAULTFBCONFIG) that can be used to manually specify the rendering attributes of the default FB config that VirtualGL uses whenever a 3D application does not specify a desired set of visual attributes (which it would normally do by calling glXChooseVisual().) Refer to the User's Guide for more information.

7. Worked around an issue whereby using very large fonts with glXUseXFont() would cause Pixmap allocation failures with certain X servers.
