Weekly status for the week of the 18th to the 24th of September 2017.
Introduction
The main highlight of this week was the release of LXD 2.18.
We’ve otherwise been busy tracking down and fixing a number of issues, extended the user-agent string that LXD uses when talking to our image server and been working on a number of fixes for LXC 2.1.
We’re also making good progress on the stable release branches and hope to get to tag a number of stable bugfix releases next week.
Upcoming conferences and events
- Open Source Summit Europe (Prague, October 2017)
- Linux Piter 2017 (St. Petersburg - November 2017)
Ongoing projects
The list below is feature or refactoring work which will span several weeks/months and can’t be tied directly to a single Github issue or pull request.
- External authentication support for LXD servers
- LXD documentation improvement
- Distributed database for LXD clustering
- Stable release work for LXC, LXCFS and LXD.

This section is used to track the work done in downstream Linux distributions to ship the latest LXC, LXD and LXCFS as well as work to get various software to work properly inside containers.
Ubuntu
- LXD 2.18-0ubuntu1 was uploaded to the Ubuntu 17.10 archive.
- LXD 2.18-0ubuntu2 was uploaded a bit later with a couple of cherry-picked fixes.
Snap
