# Release 3.0.16 #978

Closed jcvenegas closed 6 years ago

jcvenegas commented 6 years ago

Welcome to Clear Containers release 3.0.16!.

For this release we have updated virtcontainers package which provides important refactoring of the code regarding the proxy and shim interfaces. Our documentation was updated to remove references to Clear Containers proxy service (now each VM has its own proxy). The collect-data script now collects Kata Containers data. Finally, now the kernel params line options defined in Clear Containers configuration file will take priority over defaults defined by the runtime.

I'll note, it looks like the metrics CI failed in some odd way - I'll go check that out - no doubt spurious and not related to this PR.

grahamwhaley commented 6 years ago

Just to update on the metrics CI status - this failed due to timeouts trying to connect to the docker hub.
