LXD 5.9 has been released

Introduction

The LXD team is very excited to announce the release of LXD 5.9!

This is going to be our last release of 2022.
We wish you all happy holidays and look forward to seeing you all in 2023!

As the last release of the year, this was also a shortened development cycle of just three weeks, most of which was spent on bugfixes and performance improvements, perfect to wrap up the year!

Enjoy!

New features and highlights

Network zones project feature

Prior to this release, network zones (DNS) were tied to features.networks, effectively requiring the use of OVN in order to get per-project DNS zones.

This has now been split up into a new features.networks.zones allowing for use of per-project zones in environment that don’t use features.networks. When dealing with a shared network, that network may specify multiple zones (comma separated). Each zone will then only contain records for the project it belong to.

Hi!!

The section is in the wrong place. The position of " Complete changelog".

Fixed thanks!

Is the new zones feature documented yet? I would like to play around with it. I will also watch the YouTube video again.

Yes, see How to configure network zones - LXD documentation

Specifically Project views is the new feature.

See DNS not created for containers created in user projects - #20 by tomp for an example of such a setup.

Also see the video for the original network zones feature:

The lxc network list-leases command has also been updated to align with the automatic entries added to network zone project views. You can use the --project flag to alter the view for the list-leases command.

Perfect. Thank you, Thomas. That helps a lot.
