CRI-O v1.8.0 and v1.0.4 released
I’m pleased to announce two new CRI-O releases. The new CRI-O v1.8.0 is our new major release supporting Kubernetes 1.8 while CRI-O v1.0.4 is a new patch release targetting Kubernetes 1.7.
The new v1.8.x release cycle is meant to follow Kubernetes 1.8 and as such it comes with new features from the CRI interface along with many bugs and performance fixes and additional Prometheus metrics focused on the CRI API operations in CRI-O:

[...]The v1.0.4 release is a minor release with bug fixes back ported along with the new Prometheus metrics from above.
cri-o-1.8 is released into Fedora Rawhide. cri-o-1.0.4 is in updates testing for Fedora 27/26.
Note: OpenShift Origin currently requires Kubernetes 1.7, so we are sticking with the default CRI-O for these releases as 1.0 for now.
Packages should be available for Ubuntu/CentOS shortly. Please test the new version and send feedback or suggestions. Don’t be shy. Reach out to us on Github, Freenode #cri-o, or directly tweet me :)
Grazie mille!
