/ 2017-01-11
+{: #v1-11-0}
+
+Nearly three months after the previous release, there is a long list
+of improvements and bug-fixes, many of them making planner rules
+smarter.
+
+Several adapters have improvements:
+
+* The JDBC adapter can now push down DML (`INSERT`, `UPDATE`, `DELETE`),
+  windowed aggregates (`OVER`), `IS NULL` and `IS NOT NULL` operators.
+* The Cassandra adapter now supports authentication.
+* Several key bug-fixes in the Druid adapter.
+
+For correlated and uncorrelated sub-queries, we generate more
+efficient plans (for example, in some correlated queries we no longer
+require a sub-query to generate the values of the correlating
+variable), can now handle multiple correlations, and have also fixed a
+few correctness bugs.
+
+New SQL syntax:
+
+* `CROSS APPLY` and `OUTER APPLY`;
+* `MINUS` as a synonym for `EXCEPT`;
+* an `AS JSON` option for the `EXPLAIN` command;
+* compound identifiers in the target list of `INSERT`, allowing you to
+  insert into individual fields of record-valued columns (or column
+  families if you are using the Apache Phoenix adapter).
+
+A variety of new and extended built-in functions: `CONVERT`, `LTRIM`,
+`RTRIM`, 3-parameter `LOCATE` and `POSITION`, `RAND`, `RAND_INTEGER`,
+and `SUBSTRING` applied to binary types.
+
+There are minor but potentially breaking API changes in
+[<a href="https://issues.apache.org/jira/browse/CALCITE-1519">CALCITE-1519</a>]
+\(interface `SubqueryConverter` becomes `SubQueryConverter` and some
+similar changes in the case of classes and methods\) and
+[<a href="https://issues.apache.org/jira/browse/CALCITE-1530">CALCITE-1530</a>]
+\(rename `Shuttle` to `Visitor`, and create a new class `Visitor<R>`\).
+See the cases for more details.
+
+Compatibility: This release is tested
+on Linux, macOS, Microsoft Windows;
+using Oracle JDK 1.7, 1.8;
+Guava versions 14.0 to 19.0;
+Druid version 0.9.1.1;
+other software versions as specified in `pom.xml`.
