# Release 16.09 (“Flounder”, 2016/09/??)

In addition to numerous new and upgraded packages, this release has the following highlights:

- PXE "netboot" media has landed in . See for documentation.

- Xorg-server-1.18.*. If you choose `"ati_unfree"` driver, 1.17.* is still used due to ABI incompatibility.

The following new services were added since the last release:

- `(this will get automatically generated at release time)`

When upgrading from a previous release, please be aware of the following incompatible changes:

- Shell aliases for systemd sub-commands were dropped: `start`, `stop`, `restart`, `status`.

- Redis now binds to 127.0.0.1 only instead of listening to all network interfaces. This is the default behavior of Redis 3.2

- Gitlab's maintainence script gitlab-runner was removed and split up into the more clearer gitlab-run and gitlab-rake scripts because gitlab-runner is a component of Gitlab CI.

- `services.xserver.libinput.accelProfile` default changed from `flat` to `adaptive`, as per official documentation.

Other notable improvements:

- Revamped grsecurity/PaX support. There is now only a single general-purpose distribution kernel and the configuration interface has been streamlined. Desktop users should be able to simply set

      security.grsecurity.enable = true

  to get a reasonably secure system without having to sacrifice too much functionality. See for documentation
