- `kanidm` has been updated to 1.1.0-alpha.10 and now requires a TLS certificate and key. It will always start `https` and-–-if enabled-–-an LDAPS server and no HTTP and LDAP server anymore.
- riak package removed along with `services.riak` module, due to lack of maintainer to update the package.
- ppd files in `pkgs.cups-drv-rastertosag-gdi` are now gzipped. If you refer to such a ppd file with its path (e.g. via [hardware.printers.ensurePrinters](options.html#opt-hardware.printers.ensurePrinters)) you will need to append `.gz` to the path.
- xow package removed along with the `hardware.xow` module, due to the project being deprecated in favor of `xone`, which is available via the `hardware.xone` module.
- dd-agent package removed along with the `services.dd-agent` module, due to the project being deprecated in favor of `datadog-agent`, which is available via the `services.datadog-agent` module.
- `teleport` has been upgraded to major version 10. Please see upstream [upgrade instructions](https://goteleport.com/docs/ver/10.0/management/operations/upgrading/) and [release notes](https://goteleport.com/docs/ver/10.0/changelog/#1000).
- `lib.closePropagation` now needs that all gathered sets have an `outPath` attribute.
- lemmy module option `services.lemmy.settings.database.createLocally`
moved to `services.lemmy.database.createLocally`.
- virtlyst package and `services.virtlyst` module removed, due to lack of maintainers.
- The `nix.checkConfig` option now fully disables the config check. The new `nix.checkAllErrors` option behaves like `nix.checkConfig` previously did.
- `generateOptparseApplicativeCompletions` and `generateOptparseApplicativeCompletion` from `haskell.lib.compose`
(and `haskell.lib`) have been deprecated in favor of `generateOptparseApplicativeCompletions` (plural!) as
provided by the haskell package sets (so `haskellPackages.generateOptparseApplicativeCompletions` etc.).
The latter allows for cross-compilation (by automatically disabling generation of completion in the cross case).
For it to work properly you need to make sure that the function comes from the same context as the package
you are trying to override, i.e. always use the same package set as your package is coming from or – even
better – use `self.generateOptparseApplicativeCompletions` if you are overriding a haskell package set.
The old functions are retained for backwards compatibility, but yield are warning.
- The `services.graphite.api` and `services.graphite.beacon` NixOS options, and
the `python3.pkgs.graphite_api`, `python3.pkgs.graphite_beacon` and
`python3.pkgs.influxgraph` packages, have been removed due to lack of upstream
maintenance.
- The `trace` binary from `perf-linux` package has been removed, due to being a duplicate of the `perf` binary.
- The `aws` package has been removed due to being abandoned by the upstream. It is recommended to use `awscli` or `awscli2` instead.
- The [CEmu TI-84 Plus CE emulator](https://ce-programming.github.io/CEmu) package has been renamed to `cemu-ti`. The [Cemu Wii U emulator](https://cemu.info) is now packaged as `cemu`.
- `systemd-networkd` v250 deprecated, renamed, and moved some sections and settings which leads to the following breaking module changes:
* `systemd.network.networks.<name>.dhcpV6PrefixDelegationConfig` is renamed to `systemd.network.networks.<name>.dhcpPrefixDelegationConfig`.
* `systemd.network.networks.<name>.dhcpV6Config` no longer accepts the `ForceDHCPv6PDOtherInformation=` setting. Please use the `WithoutRA=` and `UseDelegatedPrefix=` settings in your `systemd.network.networks.<name>.dhcpV6Config` and the `DHCPv6Client=` setting in your `systemd.network.networks.<name>.ipv6AcceptRAConfig` to control when the DHCPv6 client is started and how the delegated prefixes are handled by the DHCPv6 client.
* `systemd.network.networks.<name>.networkConfig` no longer accepts the `IPv6Token=` setting. Use the `Token=` setting in your `systemd.network.networks.<name>.ipv6AcceptRAConfig` instead. The `systemd.network.networks.<name>.ipv6Prefixes.*.ipv6PrefixConfig` now also accepts the `Token=` setting.
