 Detailed Notes
--  When including scalarfield.h into an application, 
+-  The older version of pybind11 has a python array descriptor
+   which was incompatibile with numpy 2.x, leading to a bug
+   wehn using the python client. This bumps the pybind11
+   version to add support for numpy 2.x while retaining
+   support for numpy 1.x
+   ([PR531](https://github.com/CrayLabs/SmartRedis/pull/531))
+-  When including scalarfield.h into an application,
    MetadataBuffer was never defined. Add an explicit include
    to the header file to ensure that applications can build.
