Status in Autoware 2.0.0#

The milestones of February and April 2026 are complete. In Autoware 2.0.0:

  • The autoware.dev_env.install_dev_env Ansible playbook installs ROS 2 Humble on Ubuntu 22.04 and ROS 2 Jazzy on Ubuntu 24.04. It stops on other Ubuntu versions. See install_dev_env.yaml.
  • The Docker images are built for Humble and Jazzy, for amd64 and arm64, for example ghcr.io/autowarefoundation/autoware:universe-cuda-jazzy-2.0.0. Jazzy is the default ROS_DISTRO in docker-bake.hcl.
  • A pull request to autoware, autoware_core, or autoware_universe must pass the required build checks for both Humble and Jazzy before it can merge.

Next steps#

The milestones after Autoware 2.0.0 are the plan from the tracking issue:

  1. 2027 January: Humble soft-freeze. The standard support for Humble ends. After this date, Humble gets only critical fixes.
  2. 2027 May: Jazzy exclusive mode. The CI checks only Jazzy, and the support for Humble ends.
