+[nalgebra] ([GitHub], [Discord]) by [Dimforge] is a general-purpose
+linear-algebra library.
+
+With its version 0.26, [nalgebra] replaced the use of [generic-arrays] by
+regular Rust arrays using const-generics. See the [blog-post] to get all
+the details! In particular, this results in significant benefits:
+
+- Simpler generic programming with statically-sized vectors/matrices.
+- Much simpler debugging: inspect the content of vectors/matrices more easily.
+- Vectors and matrices with dimensions known at compile-time can be
+  constructed in a const-fn context.
