- `/var/lib/headscale` and `/var/run/headscale` is no longer created automatically, see [container docs](./docs/running-headscale-container.md)
- Prefixes are now defined per v4 and v6 range. [#1756](https://github.com/juanfont/headscale/pull/1756)
- `ip_prefixes` option is now `prefixes.v4` and `prefixes.v6`
- `prefixes.allocation` can be set to assign IPs at `sequential` or `random`. [#1869](https://github.com/juanfont/headscale/pull/1869)
