# Revision history for distribution-nixpkgs
## 1.6.2
* Expect `MonadFailDesugaring` (or equivalent behavior) to be the default,
requiring GHC >= 8.6.1. Adds support for GHC 9.2.1 (rc1).
## 1.6.1
* `Distribution.Nixpkgs.Meta`: support `aarch64-darwin`
* Render `Platform AArch64 OSX` to `"aarch64-darwin"`
* Add `Platform AArch64 OSX` to `allKnownPlatforms`
## 1.6.0
* `Distribution.Nixpkgs.PackageMap`
* `readNixpkgPackageMap`: instead of a list of arguments to pass to
`nix-env`, take path to nixpkgs and an optional nix expression
to pass to it as arguments.
* `readNixpkgPackageMap`: populate `PackageMap` with *all* attribute
paths that point to derivations instead of just one per derivation.
This fixes `resolve` not finding certain identifiers if there were
two attributes pointing to the same derivation in nixpkgs. See also
[#9](https://github.com/NixOS/distribution-nixpkgs/issues/9).
