The installable version of CircleCI 2.5.0 includes the following fixes and improvements:
- This release fixes a problem with DNS resolution failure on alpine-based containers. This problem was observed in the 2.3 release and was fixed for some service containers in 2.4. The 2.5 update fixes the issue for all service containers.
- This release includes improvements to scaling and garbage collection in the VM Service that should improve performance for installations with heavy use of
machineexecutors or remote Docker.
