An updated spice-protocol package that adds several enhancements is now available for Red Hat Enterprise Linux 6.
The spice-protocol package contains header files that describe the SPICE protocol and the QXL para-virtualized graphics card. The SPICE protocol is needed to build newer versions of the spice-client and the spice-server packages.
The spice-protocol package has been upgraded to upstream version 0.10.1, which provides a number of enhancements over the previous version, including support for USB redirection.
All users who build spice packages are advised to upgrade to this updated package, which adds these enhancements.
