+#### User-visible changes
+
+- when the package is loaded, a message warns the users if they use a version of 'htmlwidgets' < 1.5.1.9000. The latest version of this package, available on GitHub, avoids troubles with the use of dynamic graphics of the 'dygraphs' package (called by the <code>dyplot&#42;()</code> and the <code>ShinyGR()</code> functions)
+
+- it is now possible to use the GR4H and GR5H hourly models with or whithout CemaNeige. For that, in the <code>PrepGR()</code>, the <code>HydroModel</code> argument could be set to <code>"GR4H"</code> or <code>"GR5H"</code>. In the GUI, launched by <code>ShinyGR()</code> function, nothing changed, only the daily models are available
