A full list of commits can be found at `https://github.com/ansible/awx/releases/tag/<version>`. -# (TBD) +# (March 19, 2021) + +**IMPORTANT INSTALL AND UPGRADE NOTES** + +Starting in version 18.0, the [AWX Operator](https://github.com/ansible/awx-operator) is the preferred way to install AWX: https://github.com/ansible/awx/blob/devel/INSTALL.md#installing-awx + +If you have a pre-existing installation of AWX that utilizes the Docker-based installation method, this install method has ** notably changed** from 17.x to 18.x. For details, please see: + +- https://groups.google.com/g/awx-project/c/47MjWSUQaOc/m/bCjSDn0eBQAJ +- https://github.com/ansible/awx/blob/devel/tools/docker-compose +- https://github.com/ansible/awx/blob/devel/tools/docker-compose/docs/data_migration.md + +### Introducing Execution Environments + +After a hurculean effort from a number of contributors, we're excited to announce that AWX 18.0.0 introduces a new concept called Execution Environments. + +Execution Environments are container images which consist of everything necessary to run a playbook within AWX, and which drive the entire management and lifecycle of playbook execution runtime in AWX: https://github.com/ansible/awx/issues/5157. This means that going forward, AWX no longer utilizes the [bubblewrap](https://github.com/containers/bubblewrap) project for playbook isolation, but instead utilizes a container per playbook run. + +Much like custom virtualenvs, custom Execution Environments can be crafted to specify additional Python or system-level dependencies. Ansible Builder outputs images you can upload to your registry which can *then* be defined in AWX and utilized for playbook runs. + +To learn more about Ansible Builder and Execution Environments, see: https://www.ansible.com/blog/introduction-to-ansible-builder + +### Other Notable Changes + +- Removed `installer` directory. + - The Kubernetes installer has been removed in favor of [AWX Operator](https://github.com/ansible/awx-operator). + - The "Local Docker" install method has been removed in favor of the development environment. Details can be found at: https://github.com/ansible/awx/blob/devel/tools/docker-compose/README.md +- Removal of custom virtual environments https://github.com/ansible/awx/pull/9498 + - Custom virtual environments have been replaced by Execution Environments - Added user interface for the activity stream: https://github.com/ansible/awx/pull/9083 - Converted many of the top-level list views (Jobs, Teams, Hosts, Inventories, Projects, and more) to a new, permanent table component for substantially increased responsiveness, usability, maintainability, and other 'ility's: https://github.com/ansible/awx/pull/8970, https://github.com/ansible/awx/pull/9182 and many others! - Added click-to-expand details for job tables -- Add search filtering to job output https://github.com/ansible/awx/pull/9208 - Added the new migration, update, and "installation in progress" page https://github.com/ansible/awx/pull/9123 - Added the user interface for job settings https://github.com/ansible/awx/pull/8661 - Runtime errors from jobs are now displayed, along with an explanation for what went wrong, on the output page https://github.com/ansible/awx/pull/9264 |
