 - The default Android NDK version has been raised to 27, and the default SDK version to 35.
   NDK 21–26 have been removed, as they are end‐of‐life.
 
+- `nuget-to-nix` has been removed as it was deprecated in favor of `nuget-to-json`. Out-of-tree packages that were using `nuget-to-nix` should migrate to use `nuget-to-json` instead for generating .NET dependency lock files.
+
 - `conftest` since `0.60.0` has moved to use rego `v1` as default. To continue using `v0` use `--rego-version v0`. For more information about upgrading to Rego v1 syntax, see the [upstream docs](https://www.openpolicyagent.org/docs/latest/v0-upgrade/).
 
 - Zig 0.12 has been removed.
