Weekly status for the week of the 17th to the 23rd of September.
Introduction
This past week, the entire LXD team was working together in Brussels.
Part of this was to focus on two features we’ve been working on, snapshots of custom storage volumes and the upcoming LXD projects feature.
The custom storage volume snapshots have now been merged and we’ve made some excellent progress on the LXD projects.
The rest of the code merged this week was primarily bugfixes, some performance improvements and a few minor feature additions.
