   rather than dotnet 6. For packages that still need dotnet 6, use
   `dotnet-sdk_6`, etc.
 
+- `nerdfonts` has been separated into individual font packages under the namespace `nerd-fonts`. The directories for font
+  files have changed from `$out/share/fonts/{opentype,truetype}/NerdFonts` to
+  `$out/share/fonts/{opentype,truetype}/NerdFonts/<fontDirName>`, where `<fontDirName>` can be found in the
+  [official website](https://www.nerdfonts.com/font-downloads) as the titles in preview images, with the "Nerd Font"
+  suffix and any whitespaces trimmed.
