Updated Removing EOL Banner on build emails
Updated VM Service stability improvements
Bug Fix Fix issue with contexts that would break after 32 days
Bug Fix Vault auth tokens will now renew periodically to prevent expiration
Bug Fix Fix for an issue where workflow listing pages would intermittently fail to render
Bug Fix We have fixed a small number of bugs affecting processing incoming web hooks from GitHub to CircleCI.
Bug Fix For installs that are using an HTTP or HTTPS proxy, the jobs will now ignore that proxy so that setup_remote_docker works.
Bug Fix Reduced the number of connections 1.0 builders make to the PostgreSQL database.
Security Fix Security fixes for potential cross-site scripting vulnerability and HTTP header injection vulnerability
Security Fix Forked PRs can no longer write the caches of parent projects by default for security reasons. It is possible to still write parent project caches from the fork if the “Pass secrets to builds from forked pull requests” (in Advanced settings) is enabled.
Update Improved metrics for VM provisioning for machine executor. This changed metric names, so if you are monitoring VM provisioning in your install already, you will need to reconfigure the monitoring dashboards for these new metrics.
- New metrics:
- vm-service.gauges.available-vms and vm-service.gauges.running-vms replaced by vm-service.gauges.vms_by_status
- vm-service.gauges.running-tasks replaced by vm-service.gauges.tasks_by_status
- vm-service.gauges.oldest-unassigned-task replaced by vm-service.gauges.unassigned_tasks_age
Known Issue(s)
When a saved context is removed during the build graph phase it can cause a silent failure during job execution.
In some instances the metrics section becomes hidden in the settings page. Please see this Knowledge article for instructions.
