Introduction

LXD 3.1 is the first feature release following our last LTS release (3.0).
As a feature release, it will only be supported until LXD 3.2 is released next month.

We recommend critical production environments stick to the LTS branch instead.
If you’re using the snap, you can enforce that with snap refresh lxd --channel=3.0.

Note that LXD does not support downgrades, so a system that’s upgraded to LXD 3.1 will not be able to go back to LXD 3.0.0.

Note for Ubuntu users

LXD 3.1 will only be made available as a snap package. We will not be uploading it as a deb to Ubuntu 18.10 or through backports to previous releases. Moving forward all feature releases of LXD will only be available through the snap.

Note that this does NOT affect users of LXD 3.0.x as present in Ubuntu 18.04 where further bugfix/security releases will be uploaded as debs until Ubuntu 18.04 reaches end of life.

The changes in this release include

Features:

  • Introduced a new backup API and ability to export/import containers using it.
    In the CLI those are new lxc export and lxc import commands:
    asciicast
  • Made it possible to override the LXD socket path with LXD_SOCKET
  • Made it possible to disable the use of privileges containers through a new LXD_UNPRIVILEGED_ONLY environment variable.
  • Improved the lxd sql command to support interacting with both databases, support making database and schema dumps, run multiple queries an read from a script.

Hi Stéphane. I know this is an old topic, but it seems to be the first feature release for which this is true:

LXD 3.1 will only be made available as a snap package.

Would it please be possible to update the Getting started - command line page to reflect this? Currently it says that feature releases can be installed from xenial-backports on Ubuntu 16.04. The following section covering the snap package could also be updated to explain that this is the way to get feature releases from now on.

Many thanks
Andy
