LXD weekly status #44

Introduction

Another week of bugfixes for us as more and more people update to the 3.0 releases!

Quite a bit of work went into improving the handling of the two database in LXD 3.0, making it easier for us to debug issues and provide fixes to our users when something goes wrong. Work is also continuing on the new backup/restore API for LXD with it hopefully landing later this week.

We’re also excited to see LXD debuts on the Chromebooks through the new Crostini feature. This also led to a minor change to LXD to allow restricting users to unprivileged containers as was needed for those users.

Now that LXD 3.0 is mostly behind us, we’re focusing on the roadmap for the next 6 months and early preparation for LXD 3.1 to be released in a couple of weeks.
