What’s New in Release 2.19.07

Fixes

• Fixed a bug that was preventing authentication to China region ECR images in the docker executor.
• Removed the recursive chown from startup of the fileserverd service. In instances of heavy usage this was causing the startup process to take a long time, or in some cases, startup was blocked.

Known Issues

• If any changes have been made to your networking configuration from the default, you should run the following steps to ensure you can use SSH to inspect your builds (for further information on SSH reruns see the SSH Rerun Guide):
  • For customers using AWS, make sure that you have the latest Launch Configuration configured for Nomad clients, and that exiting Nomad clients were spun up using the Launch Configuration.
  • On each Nomad Client machine, create /etc/circleci/public-ipv4
  • This file should contain the public (if applicable) or private IP of the nomad client
