 │ Release notes for i3 v4.23   │
 └──────────────────────────────┘

This is i3 v4.23. This version is considered stable. All users of i3 are
strongly encouraged to upgrade.

The biggest feature of this release is i3bar’s workspace button protocol,
which allows the workspace_command program or script to filter, re-arrange,
or otherwise customize the displayed workspaces:
