+The `core.css` file has been updated to enable dynamic font scaling by default.

+Developers who had previously chosen dynamic font scaling by activating it in their global stylesheets can revert to the default setting by removing their custom CSS. In doing so, their application will seamlessly continue utilizing dynamic font scaling as it did before. It's essential to note that altering the font-size of the html element should be avoided, as it may disrupt the proper functioning of dynamic font scaling.
