 The Ginkgo team is proud to announce the new Ginkgo minor release 1.9.0.
 This release brings new features such as:
-- Supporting half precision (IEEE FP16). The type `gko::half` can now be selected in most instances as the value-type
+- Supporting half precision (IEEE FP16). The type `gko::half` can now be selected in most instances as the value type
   of a matrix, solver, preconditioner, etc. If the selected backend supports FP16 as a native type, the native type is
   used within the kernels, otherwise an overhead might occur. The new behavior is enabled by default, but it can be 
   turned off during configuration.
