+### Stateless Webserver using DAG Serialization
+
+The Webserver can now run without access to DAG Files when DAG Serialization is turned on.
+The 2 limitations we had in 1.10.7-1.10.9 (
+https://airflow.apache.org/docs/1.10.7/dag-serialization.html#limitations)
+have been resolved.
+
+The main advantage of this would be reduction in Webserver startup time for large number of DAGs.
+Without DAG Serialization all the DAGs are loaded in the DagBag during the
+Webserver startup.
+
+With DAG Serialization, an empty DagBag is created and
+Dags are loaded from DB only when needed (i.e. when a particular DAG is
+clicked on in the home page)
+
+Details: http://airflow.apache.org/docs/1.10.10/dag-serialization.html
+
+### Dummy Operators are no longer sent to executor
+
+The Dummy operators does not actually do any work and are mostly used for organizing/grouping tasks along
+with BranchPythonOperator.
+
+Previously, when using Kubernetes Executor, the executor would spin up a whole worker pod to execute a dummy task.
+With Airflow 1.10.10 tasks using Dummy Operators would be scheduled & evaluated by the Scheduler but not sent to the
+Executor. This should significantly improve execution time and resource usage.
+
+### Allow passing DagRun conf when triggering dags via UI
+
+When triggering a DAG from the CLI or the REST API, it s possible to pass configuration for the DAG run as a JSON blob.
+
+From Airflow 1.10.10, when a user clicks on Trigger Dag button, a new screen confirming the trigger request, and allowing the user to pass a JSON configuration
+blob would be show.

 the legacy Flask-admin based UI. This UI can be enabled by setting `rbac=True` in `[webserver]` section in your `airflow.cfg`.
 
 Flask-admin based UI is deprecated and new features won't be ported to it. This UI will still be the default
