+### Apollo Client (2.3.7)
+
+- Release 2.3.6 broke Typescript compilation. `QueryManager`'s
+  `getQueryWithPreviousResult` method included an invalid `variables` return
+  type in the auto-generated `core/QueryManager.d.ts` declaration file. The
+  type definition had a locally referenced path, that appears to have been
+  caused by the typescript compiler getting confused at compile/publish time.
+  `getQueryWithPreviousResult` return types are now excplicity identified,
+  which helps Typescript avoid the local type reference. For more details,
+  see https://github.com/apollographql/apollo-client/issues/3729.
