Weekly status for the week of the 18th to the 24th of June 2018.
Introduction
The main focus this week was the release of LXD 3.2.
After running into a few last minute issues with the proxy device, we finally made the release on Thursday. It’s now available in the candidate snap channel.
LXD 3.0.1 has now been pushed to all Ubuntu 18.04 users and we expect it to be made available to Ubuntu 16.04 users later this week.
We’ve now started working on the next set of features targeted at LXD 3.3 as well as fixing a number of small issues in the 3.2 release which we’ll include in the stable snap prior to release.
