+## 0.34.3
+* Non-breaking AST changes in support for the control_flow_collections and
+  spread_collections experiments.  Clients who wish to begin adding support for
+  these experiments can depend on this release of the analyzer and begin writing
+  visit methods.  The visit methods won't be added to the AstVisitor base class
+  until 0.35.0.
+* Bug fixes: #35551, #35708, #35723.
+
 ## 0.34.2
 * Removed support for the `@checked` annotation.  Please use the `covariant`
   keyword instead (#28797).
