+> <b>argmin</b> offers a range of numerical optimization methods in Rust.
+
+The previous release added (optional) L1-regularization to L-BFGS which increased the trait bounds on the acceptable types.
+Unfortunately these traits where only partially implemented for the `nalgebra` backend, therefore L-BFGS could not be used with `nalgebra` types anymore.
+The 0.2.1 release of `argmin-math` fixes this and adds an L-BFGS example for `nalgebra` types to the `examples/` directory.
