- `services.chronyd` is now started with additional systemd sandbox/hardening options for better security.
+
- PostgreSQL has opt-in support for [JIT compilation](https://www.postgresql.org/docs/current/jit-reason.html). It can be enabled like this:
+
```nix
+
{
+
services.postgresql = {
+
enable = true;
+
enableJIT = true;
+
};
+
}
+
```
+
- `services.dhcpcd` service now don't solicit or accept IPv6 Router Advertisements on interfaces that use static IPv6 addresses.
- The module `services.headscale` was refactored to be compliant with [RFC 0042](https://github.com/NixOS/rfcs/blob/master/rfcs/0042-config-option.md). To be precise, this means that the following things have changed:

## JIT (Just-In-Time compilation) {#module-services-postgres-jit}
+
+
[JIT](https://www.postgresql.org/docs/current/jit-reason.html)-support in the PostgreSQL package
+
is disabled by default because of the ~300MiB closure-size increase from the LLVM dependency. It
+
can be optionally enabled in PostgreSQL with the following config option:
+
+
```nix
+
{
+
services.postgresql.enableJIT = true;
+
}
+
```
+
+
This makes sure that the [`jit`](https://www.postgresql.org/docs/current/runtime-config-query.html#GUC-JIT)-setting
+
is set to `on` and a PostgreSQL package with JIT enabled is used. Further tweaking of the JIT compiler, e.g. setting a different
+
query cost threshold via [`jit_above_cost`](https://www.postgresql.org/docs/current/runtime-config-query.html#GUC-JIT-ABOVE-COST)
+
can be done manually via [`services.postgresql.settings`](#opt-services.postgresql.settings).
+
+
The attribute-names of JIT-enabled PostgreSQL packages are suffixed with `_jit`, i.e. for each `pkgs.postgresql`
+
(and `pkgs.postgresql_<major>`) in `nixpkgs` there's also a `pkgs.postgresql_jit` (and `pkgs.postgresql_<major>_jit`).
+
Alternatively, a JIT-enabled variant can be derived from a given `postgresql` package via `postgresql.withJIT`.
+
This is also useful if it's not clear which attribute from `nixpkgs` was originally used (e.g. when working with
+
[`config.services.postgresql.package`](#opt-services.postgresql.package) or if the package was modified via an
+
overlay) since all modifications are propagated to `withJIT`. I.e.
+
+
```nix
+
with import <nixpkgs> {
+
overlays = [
+
(self: super: {
+
postgresql = super.postgresql.overrideAttrs (_: { pname = "foobar"; });
+
})
+
];
+
};
+
postgresql.withJIT.pname
+
```
+
+
evaluates to `"foobar"`.
