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.
