Hello,

You are right, we broke API compatibility between Gazebo 1.2 and Gazebo 1.3 without a proper tick-tock. Version 1.2 of Gazebo marked when Gazebo first started to adopt the tick-tock model, and we obviously missed a function. We have since improved our efforts, and there is a person looking into maintaining API and ABI compatibility within Gazebo.

Thank you for your report and concern. We'll do our best to prevent future occurrences.

Thanks, Nate. I appreciate all the hard work you and the Gazebo developers are doing. It's really improving rapidly.

It's good you are starting tick-tock now. That will help a lot. 

But, the bigger issue is that 1.3 should not have been added to ROS after Groovy final. It needed to wait until Hydro (which is not very long).

Regards,
