 - `zfs` was updated from 2.1.x to 2.2.0, [enabling newer kernel support and adding new features](https://github.com/openzfs/zfs/releases/tag/zfs-2.2.0).
 
+- Elixir now defaults to version
+  [v1.15](https://elixir-lang.org/blog/2023/06/19/elixir-v1-15-0-released/).
+
 - A new option was added to the virtualisation module that enables specifying explicitly named network interfaces in QEMU VMs. The existing `virtualisation.vlans` is still supported for cases where the name of the network interface is irrelevant.
 
 - DocBook option documentation is no longer supported, all module documentation now uses markdown.
