 # Release notes
 
+## [v4.0.1](https://github.com/mdn/browser-compat-data/releases/tag/v4.0.1)
+
+August 26, 2021
+
+### Notable changes
+
+- `css.types.ellipse` was moved to `css.types.basic-shape.ellipse` to correct improper nesting of features. ([#12075](https://github.com/mdn/browser-compat-data/pull/12075))
+
+- `css.types.filter-function.constrast` was renamed to `css.types.filter-function.contrast` to correct a typo. ([#12074](https://github.com/mdn/browser-compat-data/pull/12074))
+
+- The following non-existent, long-removed, or otherwise irrelevant features have been removed:
+
+  - `api.FileError` ([#12089](https://github.com/mdn/browser-compat-data/pull/12089))
+  - `api.Headers.getAll` ([#12166](https://github.com/mdn/browser-compat-data/pull/12166))
+  - `api.Window.onpaint` ([#12167](https://github.com/mdn/browser-compat-data/pull/12167))
+  - `api.XRPermissionDescriptor` ([#10672](https://github.com/mdn/browser-compat-data/pull/10672))
+
+### Known issues
+
+- In [v3.3.9](https://github.com/mdn/browser-compat-data/releases/tag/v3.3.9), the structure of features for `css.properties.place-content`, `place-items`, and `place-self` changed ([#11214](https://github.com/mdn/browser-compat-data/pull/11214)). This is an incomplete fix to the problem of undocumented namespaces appearing in places where you might otherwise expect compatability data. The restructuring of the data is a work in progress and may change again in a future release. See [#6175](https://github.com/mdn/browser-compat-data/issues/6175) for more information.

 ### Notable changes
 
 - [Deno](https://deno.land/), the JavaScript and TypeScript runtime, has been added as a new engine. Deno data is included for JavaScript and some Web APIs, much like Node.js data. ([#10753](https://github.com/mdn/browser-compat-data/pull/10753))
