[haskell-flake](https://github.com/srid/haskell-flake) makes writing Nix `flake.nix` for Haskell projects simpler.

This release includes fine-grained default settings for configuring multiple packages (e.g.: all local packages) easily. It includes several fixes, and is being used in most Haskell projects at [Juspay](https://juspay.in/) as well as open source projects like [`hackage-server`](https://github.com/haskell/hackage-server/blob/bec983da63c867781983cdcb2fad315addc0d041/flake.nix#L44-L83).

`haskell-flake` uses `flake-parts` (which brings NixOS-like module system to Nix flakes). If you’d like to run services (e.g.: postgres, redis, the Haskell app, etc.) locally for your Haskell project all managed by Nix, checkout [`services-flake`](https://community.flake.parts/services-flake).
