 In our continuous effort to enhance the NSPanel's utility and efficiency, we're pleased to announce that the Home page now accommodates a fourth value, complete with its icon.
 This addition allows for a more comprehensive at-a-glance view of your essential metrics directly from the home screen, ensuring that crucial information is always just a glance away.
 
+### Automatic Font Size Adjustment for Entity Page Values
+We've enhanced the entities pages with an automatic font size adjustment feature to improve the display of values, especially for longer strings or values with lengthy units.
+This smart adjustment reduces the occurrence of truncated values by dynamically resizing the font based on the string length.
+While the selection of fonts for the panel remains limited, this automatic resizing significantly enhances readability, ensuring that all displayed information is clear and fully visible at a glance.
