Over the next few hours we will be removing the Xcode 11.3.0 and 11.4.0 images and redirecting requests for these images to 11.3.1 and 11.4.1 respectively.
Doing this will allow us to free up vital space on our fleet to ensure we can get the next round of Xcode images out to customers as soon as possible.
How Will This Affect Jobs?
11.3.1 and 11.4.1 are only minor bug fix releases and have minimal minor supporting software changes in the images. This means there should be no noticeable impact to customer jobs on these images.
Once 11.3.0 and 11.4.0 have been removed, requests for these images will be redirected to 11.3.1 and 11.4.1 respectively, so no config change is required if you wish to use these images.
If you do experience any issues once this change goes live, please contact support referencing this announcement and we will provide assistance.
