 ### JS API
 
+* Backport the deprecation options (`fatalDeprecations`, `futureDeprecations`,
+  and `silenceDeprecations`) to the legacy JS API. The legacy JS API is itself
+  deprecated, and you should move off of it if possible, but this will allow
+  users of bundlers and other tools that are still using the legacy API to
+  still control deprecation warnings.

 * Fix a bug where accessing `SourceSpan.url` would crash when a relative URL was
   passed to the Sass API.

 * Fix a race condition where the embedded host could fail to shut down if it was
