+## 4.13.0 PySimpleGUI 18-Dec-2019
+
+Table and Tree header colors, expanded Graph methods
+
+* Element.expand new parameter - expand_row. If true then row will expand along with the widgets. Provides better resizing control
+* Using math.floor now instead of an int cast in Graph Element's unit conversions
+* Graph.draw_point - now using caller's graph units for specifying point size
+* Graph.draw_circle - converted radius size from user's graph units.
+* Graph.draw_circle - added line_width parameter
+* Graph.draw_oval - added line_width parameter
+* Graph.get_figures_at_location - new method for getting a list of figures at a particular point
+* Graph.get_bounding_box - returns bounding box for a previously drawn figure
+* Table and Tree Elements
+	* 3 new element creation parameters
+		* header_text_color - color of the text for the column headings
+		* header_background_color - color of the background of column headings
+		* header_font - font family, style , size for the column headings
+	* Defaults to using the current look and feel setting
+		* Uses similar algorithm as Tabs - Input Text background and text colors are used
+* Spin element - fixed bug that showed "None" if default value is "None"
+* Test Harness sets incorrect look and feel on purpose so a random one is chosen
+
 ### Upcoming
 
 There will always be overlapping work as the ports will never actually be "complete" as there's always something new that can be built.  However there's a definition for the base functionality for PySimpleGUI.  This is what is being strived for with the currnt ports that are underway.

+
+Table and Tree header colors, expanded Graph methods
+
+* Element.expand new parameter - expand_row. If true then row will expand along with the widgets. Provides better resizing control
+* Using math.floor now instead of an int cast in Graph Element's unit conversions
+* Graph.draw_point - now using caller's graph units for specifying point size
+* Graph.draw_circle - converted radius size from user's graph units.
+* Graph.draw_circle - added line_width parameter
+* Graph.draw_oval - added line_width parameter
+* Graph.get_figures_at_location - new method for getting a list of figures at a particular point
+* Graph.get_bounding_box - returns bounding box for a previously drawn figure
+* Table and Tree Elements
+	* 3 new element creation parameters
+		* header_text_color - color of the text for the column headings
+		* header_background_color - color of the background of column headings
+		* header_font - font family, style , size for the column headings
+	* Defaults to using the current look and feel setting
+		* Uses similar algorithm as Tabs - Input Text background and text colors are used
+* Spin element - fixed bug that showed "None" if default value is "None"
+* Test Harness sets incorrect look and feel on purpose so a random one is chosen

 ### Upcoming
 
 There will always be overlapping work as the ports will never actually be "complete" as there's always something new that can be built.  However there's a definition for the base functionality for PySimpleGUI.  This is what is being strived for with the currnt ports that are underway.
