- FoundationDB now defaults to major version 7.
- Support for WiFi6 (IEEE 802.11ax) and WPA3-SAE-PK was enabled in the `hostapd` package, along with a significant rework of the hostapd module.
## New Services {#sec-release-23.11-new-services}
- [MCHPRS](https://github.com/MCHPR/MCHPRS), a multithreaded Minecraft server built for redstone. Available as [services.mchprs](#opt-services.mchprs.enable).

- The latest version of `clonehero` now stores custom content in `~/.clonehero`. See the [migration instructions](https://clonehero.net/2022/11/29/v23-to-v1-migration-instructions.html). Typically, these content files would exist along side the binary, but the previous build used a wrapper script that would store them in `~/.config/unity3d/srylain Inc_/Clone Hero`.
- The `services.hostapd` module was rewritten to support `passwordFile` like options, WPA3-SAE, and management of multiple interfaces. This breaks compatibility with older configurations.
- `hostapd` is now started with additional systemd sandbox/hardening options for better security.
- `services.hostapd.interface` was replaced with a per-radio and per-bss configuration scheme using [services.hostapd.radios](#opt-services.hostapd.radios).
- `services.hostapd.wpa` has been replaced by [services.hostapd.radios.<name>.networks.<name>.authentication.wpaPassword](#opt-services.hostapd.radios._name_.networks._name_.authentication.wpaPassword) and [services.hostapd.radios.<name>.networks.<name>.authentication.saePasswords](#opt-services.hostapd.radios._name_.networks._name_.authentication.saePasswords) which configure WPA2-PSK and WP3-SAE respectively.
- The default authentication has been changed to WPA3-SAE. Options for other (legacy) schemes are still available.
- `python3.pkgs.fetchPypi` (and `python3Packages.fetchPypi`) has been deprecated in favor of top-level `fetchPypi`.
- `mariadb` now defaults to `mariadb_1011` instead of `mariadb_106`, meaning the default version was upgraded from 10.6.x to 10.11.x. See the [upgrade notes](https://mariadb.com/kb/en/upgrading-from-mariadb-10-6-to-mariadb-10-11/) for potential issues.
