+#### Don't lowercase element names in CSS selectors ([#6947](https://github.com/prettier/prettier/pull/6947) by [@ark120202](https://github.com/ark120202))
+
+Previously, Prettier already preserved casing of unknown element names, but it did lowercase names of HTML elements.
+This caused issues when CSS was applied to a case-sensitive document and an there was an element with the same name as in HTML, which is the case in NativeScript.
+Prettier now always preserves original casing.
