 h2. Upgrade Notes:
  * Upgrading from 0.18 requires issuing a full flush of all the indices in the cluster (@curl host:9200/_flush@) before shutting down the cluster, with no indexing operations happening after the flush.
  * The local gateway state structure has changed, a backup of the state files is created when upgrading, they can then be used to downgrade back to 0.18. Don't downgrade without using them.
+

+ * API: Multi Search ("#1722":http://github.com/elasticsearch/elasticsearch/issues/issue/1722)

+ * Return 503 for search against a node which is not yet ready ("#1713":http://github.com/elasticsearch/elasticsearch/issues/issue/1713)

+ * StackOverflowError when accessing NodeIndicesStats.refresh() ("#1706":http://github.com/elasticsearch/elasticsearch/issues/issue/1706)

+ * Search: When using @_all@ for types, field name/type resolution might fail ("#1704":http://github.com/elasticsearch/elasticsearch/issues/issue/1704)
