Weekly status for the week of the 5th to the 11th of November.
Introduction
Our focus this past week was on finishing up the container refresh feature for LXD 3.7, then fixing a few more minor bugs before we finally released LXD 3.7 on Thursday.
This was followed by the usual amount of packaging work to get this new release to our users, finishing with it being promoted to the stable channel today.
This week, the entire LXD team is travelling to Vancouver, BC for the Linux Plumbers Conference and Kernel Summit. If you’re over there, come say Hi, we’ll be running the containers micro-conference. If you’re not, you you should expect us to be slightly less reactive than usual since we’ll be pretty busy over there.
We’re hiring!
The LXD team at Canonical is hiring!
We’re looking for a work from home software engineer based in the Americas or EMEA.
This is to work on LXD itself, designing and implementing new features, helping our users and squashing those pesky bugs!
