+# Development report for 22 May 2017
+
+The tenth weekly development report. Feel free to send PRs if you want to add to these reports (or correct them).
+
+There is now a new [linuxkit/virtsock] repository that contains Go bindings and sample code for 
+Hyper-V sockets and virtio sockets.
+
+A [SIG Security](https://github.com/linuxkit/linuxkit/blob/master/sigs/security/README.md) has been instituted and there will be a [call on 24 May 2017](https://github.com/linuxkit/linuxkit/blob/master/reports/sig-security/2017-05-24.md).
+
+## Overview
+
+- We have mostly added a registry and hub org override so you can do `make ORG=myorg` when building packages, rather than pushing to the `linuxkit` org.
+- ongoing work has continued to move all builds to use the same Alpine base package. [linuxkit/linuxkit#1856] [@rneugeba]
+- Label support - images may now specify an `org.mobyproject.config` label which contains a JSON version of the config. Anything set in this config will be the default, but can be overridden by the yaml file. In many cases this means that the yaml is nor needed, simplifying the config a lot. [linuxkit/linuxkit#1862] [@justincormack]
+- Testing has been significantly improved and more tests are being added.
