Ubuntu / ROS release cadence

Ubuntu releases long-term support (LTS) distributions in April of even years with 5 years of support. At any given time, 2 or 3 Ubuntu LTS releases are supported.

ROS releases a new distribution in May every year:

  • In even years, it is an LTS release, with support for 5 years on the latest Ubuntu LTS (starting with ROS Humble)
  • In odd years, it has ~18 months of support on the same Ubuntu version as most recent ROS LTS

With releases in April and May, the LTS ROS and Ubuntu support windows are almost perfectly aligned.

Gazebo release cadence and ROS alignment

Gazebo is released in August or September every year using the most recent Ubuntu LTS. Each Gazebo release will be supported by the next ROS distribution to be released the following May. The Gazebo support window should match the support window of the co-supported ROS distribution.

In the year before Ubuntu and ROS LTS releases, the Gazebo release also has 5 years of long-term support.
