Highlights In addition to numerous new and upgraded packages, this release has the following highlights:
New Services The following new services were added since the last release: Besides the existing module which targets Prometheus-1 a new module has been added which targets Prometheus-2. Both modules can be enabled at the same time. In fact this is needed for upgrading existing Prometheus-1 data to Prometheus-2 .
Backward Incompatibilities When upgrading from a previous release, please be aware of the following incompatible changes: The option has been removed. The directory where Prometheus will store its metric data will now always be set to /var/lib/prometheus and to /var/lib/prometheus2 when using .
Other Notable Changes The module gained an option named which makes the generated configuration.nix 5 manual page include all options from all NixOS modules included in a given configuration.nix configuration file. Currently, it is set to false by default as enabling it frequently prevents evaluation. But the plan is to eventually have it set to true by default. Please set it to true now in your configuration.nix and fix all the bugs it uncovers.
