containerd 1.0.2-rc.1 Welcome to the v1.0.2-rc.1 release of containerd! *This is a pre-release of containerd* This is the second patch release for `containerd` in the 1.0 series. There are several fixes to reduce memory usage and garbage collection pressure in the shim. The content store has a few fixes to address cases where download resumption wasn't working properly. The image store has fixes to be more efficient and to handle edge cases in the garbage collector. Less CPU will be used when collecting cgroup metrics. The most critical fix addresses a hang in runc that can happen due to a race condition around FIFOs. Make sure to update your runc binary if you are affected. The fix is described in https://github.com/opencontainers/runc/pull/1698. Make sure to update to the runc version in https://github.com/containerd/containerd/blob/master/RUNC.md to ensure you are not affected. In addition to the above, a few fixes for handling of layer files have been backported. https://github.com/containerd/containerd/pull/2063 addresses an issue where duplicate directory entries can land in a layer diff if both the metadata and a child entry are changed. https://github.com/containerd/containerd/pull/2103 where whiteout files for parent directories may be missing. The license of the dependency `BurntSushi/toml` has been updated to an MIT license. We also now ensure that the vendor directory contents are as expected. Please try out the release binaries and report any issues at https://github.com/containerd/containerd/issues.
