-The Sanitizer API is scheduled to be launched in stages. The API availability
+An initial version of the Sanitizer API is enabled by default. Additional
+features are scheduled to be launched in stages. The API availability
 can be controlled via flags:
 
-* `--enable-blink-features=SanitizerAPIv0`: This includes the basic Sanitizer
-  API with configuration and the `Element.setHTML` method, but not the
-  `.sanitizeFor` or `.sanitize` methods. This flag is on by default.
-* `--enable-blink-features=SanitizerAPI`: This includes `SanitizerAPv0`
-  plus the sanitization methods of the `Sanitizer` object, as specified
-  as of 04/2022. These APIs are likely to change.
+* `--enable-blink-features=SanitizerAPI`: This includes the sanitization
+  methods of the `Sanitizer` object, as specified as of 04/2022.
+These APIs are likely to change.
 
 The general `--enable-experimental-web-platform-features` flag implies the full
 `--enable-blink-features=SanitizerAPI` feature set.
