RHEA-2013:1573 - Product Enhancement Advisory

Topic

Updated spice-protocol packages that add various enhancements are now available
for Red Hat Enterprise Linux 6.

Description

The spice-protocol packages provide header files to 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 packages have been upgraded to upstream version 0.12.6, which
provides a number of enhancements over the previous version, including file copy
support, and end-of-line conversion for copying and pasting text using clipboard
when the client and guest conventions differ, or when there are different
operating systems running. (BZ#965812)

This update also adds the following enhancement:

• The continuity of video playbacks over limited bandwidth has improved. There

are now fewer occurrences of scenes dropping and pauses, which leads to a better
user experience. After this update, the video bit-rate and the playback latency
are dynamically adjusted, using periodic reports from the client. The bandwidth
and latency estimations of past video playbacks are now used for improving the
initial parameter settings of future video playbacks. (BZ#978410)

Users of spice-protocol are advised to upgrade to these updated packages, which
add these enhancements.
