Hi All,

The new simulator_gazebo 1.6
release<http://ros.org/wiki/simulator_gazebo/ChangeList/1.6> and
the pr2_simulator 1.8
release<http://www.ros.org/wiki/pr2_simulator/ChangeList/1.8> shipped
with ROS Fuerte <http://ros.org/wiki/fuerte>, are based on the Gazebo 1.0.0
release candidate which is now considered API stable.

On the gazebo side, major changes from Electric
simulator_gazebo<http://ros.org/wiki/simulator_gazebo/ChangeList/1.4>
(pre
gazebo-1.0.0-RC) to the Fuerte
version<http://ros.org/wiki/simulator_gazebo/ChangeList/1.6>
(gazebo-1.0.0-RCX) can
be found on the gazebo change list wiki
page<http://gazebo.willowgarage.com/wiki/change_list>.
 Notably, the new Gazebo plugins have been redesigned to be more flexible
to the end-users, but unfortunately, this means the new plugin API is not
backwards compatible with the old version.  To convert old style plugins to
the 1.0.0-RC plugin, please take a quick look at the plugin
tutorials<http://gazebosim.org/wiki/tutorials/plugins>,
in particular, this
tutorial<http://gazebosim.org/wiki/tutorials/plugins/converting_old_plugins>
tries
to provide an overview on the conversion process.  For additional
reference, you can also take a look at the updates in
gazebo_plugins<http://ros.org/wiki/gazebo_plugins>
 and pr2_gazebo_plugins <http://ros.org/wiki/pr2_gazebo_plugins> packages.
 For questions or troubleshooting the conversion process, please make use
of answers <http://answers.ros.org/questions/> or the gazebo mailing
list<https://kforge.ros.org/mailman/listinfo/gazebo-list>
.

Lastly, you might have noticed that the gazebo
project<http://gazebosim.org/> has
been migrated from sourceforge to kforge (see the gazebo project page on
kforge <https://kforge.ros.org/projects/gazebo/>), please submit
gazebo-specific tickets to the new
trac<https://code.ros.org/trac/ros-pkg/report/8> and
feel free to checkout the mercurial
repository<https://kforge.ros.org/projects/gazebo/services/hg/>
.

Thanks,
John
