[services.grafana.provision.dashboards.settings.apiVersion](#opt-services.grafana.provision.dashboards.settings.apiVersion)).
- Instead of declaring datasources and dashboards in pure Nix, it's also possible
to specify configuration files (or directories) with YAML instead using
[services.grafana.provision.datasources.path](#opt-services.grafana.provision.datasources.path) (or
[services.grafana.provision.dashboards.path](#opt-services.grafana.provision.dashboards.path). This is useful when having
provisioning files from non-NixOS Grafana instances that you also want to
deploy to NixOS.
__Note:__ secrets from these files will be leaked into the store unless you use a
[**file**-provider or env-var](https://grafana.com/docs/grafana/latest/setup-grafana/configure-grafana/#file-provider) for secrets!
- `services.grafana.provision.notifiers` is not affected by this change because
this feature is deprecated by Grafana and will probably be removed in Grafana 10.
It's recommended to use `services.grafana.provision.alerting.contactPoints` instead.
- The `services.grafana.provision.alerting` option was added. It includes suboptions for every alerting-related objects (with the exception of `notifiers`), which means it's now possible to configure modern Grafana alerting declaratively.
- Synapse now requires entries in the `state_group_edges` table to be unique, in order to prevent accidentally introducing duplicate information (for example, because a database backup was restored multiple times). If your Synapse database already has duplicate rows in this table, this could fail with an error and require manual remediation.
- The `diamond` package has been update from 0.8.36 to 2.0.15. See the [upstream release notes](https://github.com/bbuchfink/diamond/releases) for more details.
- The `guake` package has been updated from 3.6.3 to 3.9.0, see the [changelog](https://github.com/Guake/guake/releases) for more details.
- The `netlify-cli` package has been updated from 6.13.2 to 12.2.4, see the [changelog](https://github.com/netlify/cli/releases) for more details.
- `dockerTools.buildImage`'s `contents` parameter has been deprecated in favor of `copyToRoot`.
Use `copyToRoot = buildEnv { ... };` or similar if you intend to add packages to `/bin`.
- The `proxmox.qemuConf.bios` option was added, it corresponds to `Hardware->BIOS` field in Proxmox web interface. Use `"ovmf"` value to build UEFI image, default value remains `"bios"`. New option `proxmox.partitionTableType` defaults to either `"legacy"` or `"efi"`, depending on the `bios` value. Setting `partitionTableType` to `"hybrid"` results in an image, which supports both methods (`"bios"` and `"ovmf"`), thereby remaining bootable after change to Proxmox `Hardware->BIOS` field.
- memtest86+ was updated from 5.00-coreboot-002 to 6.00-beta2. It is now the upstream version from https://www.memtest.org/, as coreboot's fork is no longer available.
- Option descriptions, examples, and defaults writing in DocBook are now deprecated. Using CommonMark is preferred and will become the default in a future release.
- The `documentation.nixos.options.allowDocBook` option was added to ease the transition to CommonMark option documentation. Setting this option to `false` causes an error for every option included in the manual that uses DocBook documentation; it defaults to `true` to preserve the previous behavior and will be removed once the transition to CommonMark is complete.
- The Redis module now persists each instance's configuration file in the state directory, in order to support some more advanced use cases like Sentinel.
- `protonup` has been aliased to and replaced by `protonup-ng` due to upstream not maintaining it.
- The udisks2 service, available at `services.udisks2.enable`, is now disabled by default. It will automatically be enabled through services and desktop environments as needed.
This also means that polkit will now actually be disabled by default. The default for `security.polkit.enable` was already flipped in the previous release, but udisks2 being enabled by default re-enabled it.
