EDIT: Due to the customer feedback we have received we’ve decided to not change the default image for the machine executor in April 2019. We are now working on a plan for making this update safer and more compatible for customer jobs. We will update here as we have a new date for the change and a plan for rolling the change out.
We are excited to announce a new machine executor image with Ubuntu 16.04 and Docker 18.09.3. The new image is
ubuntu-1604:201903-01, and is available now. See the machine executor docs for more information about how to use the image.
On April 28th, 2019 this image will become the default image for all
machine jobs. All existing jobs which use the default image will start using the new image on this date. The current default image will continue to be available under the name
circleci/classic:201710-01. If you would like to continue to use the current default image you must change your jobs to use
circleci/classic:201710-01 before April 28th. We recommend that you use the new image, as the circleci/classic image uses Ubuntu 14.04 which will reach end-of-life on April 30th, 2019.
