+## Version 0.1.0
+
+While version 0.1.0 sounds like a small number, this project is out there since quite some years already
+and actively used by Contour Terminal.
+
+The biggest movements lately are major performance improvements in accessing Unicode properties,
+fixing bugs as usual, and apart from being a modern C++ Unicode library, we've now also added
+a command line tool to query Unicode properties in the hope it'll be useful to you.
