+### Deprecations
+
+#### Importing files from the core or overrides layers
+
+If you import specific files from the core or overrides layers, you should import the `base` file first:
+
+```scss
+@import "node_modules/govuk-frontend/govuk/base";
+
+@import "node_modules/govuk-frontend/core/typography";
+```
+
+Importing files from the core or overrides layers without importing `base` will [no longer work as of GOV.UK Frontend v4.0](https://github.com/alphagov/govuk-frontend/issues/1800).
