 # Changelog
 
+* **v0.99 (Jule 2024)**
+	* Add new parameter `title` for setting an overall title
+	* Internal refactoring: Switch to gretl's built-in gridplot aparatus which means that all the graphics file formats supported by gretl can be used.
+	* It also means that usage via gretlcli in "display" mode works.
+	* In case the user's specification calls for just a single plot, no "multiplot" is created.
+	* The graphical interface is enhanced, with more options.
+
 * **v0.98 (April 2024)**
 	* Make width, height, fontsizes and pointsize a function of the number of variables for better readability in case of many variables.
 	* Set parameter `transparency per default to 90.
