 - The `services.fwupd` module now allows arbitrary daemon settings to be configured in a structured manner ([`services.fwupd.daemonSettings`](#opt-services.fwupd.daemonSettings)).
 
+- The `zramSwap` is now implemented with `zram-generator`, and the option `zramSwap.numDevices` for using ZRAM devices as general purpose ephemeral block devices has been removed.

 - The `unifi-poller` package and corresponding NixOS module have been renamed to `unpoller` to match upstream.
 
 - The new option `services.tailscale.useRoutingFeatures` controls various settings for using Tailscale features like exit nodes and subnet routers. If you wish to use your machine as an exit node, you can set this setting to `server`, otherwise if you wish to use an exit node you can set this setting to `client`. The strict RPF warning has been removed as the RPF will be loosened automatically based on the value of this setting.
