+
+This release comes five months after 1.21.0. It includes more than 250 resolved issues, comprising a large number of new features as well as general improvements and bug-fixes. Among others, it is worth highlighting the following.
+
+* Supports SQL hints for different kind of relational expressions (<a href="https://issues.apache.org/jira/browse/CALCITE-482">CALCITE-482</a>)
+* The project has migrated from Maven to Gradle and introduces many nice features, i.e. auto check style fix (<a href="https://issues.apache.org/jira/browse/CALCITE-2905">CALCITE-2905</a>)
+* A new Redis adaptor (<a href="https://issues.apache.org/jira/browse/CALCITE-3510">CALCITE-3510</a>)
+* More Oracle and MySQL functions are supported, i.e. Oracle XML function (<a href="https://issues.apache.org/jira/browse/CALCITE-3579">CALCITE-3579</a>, <a href="https://issues.apache.org/jira/browse/CALCITE-3580">CALCITE-3580</a>), MySQL math functions (<a href="https://issues.apache.org/jira/browse/CALCITE-3684">CALCITE-3684</a>, <a href="https://issues.apache.org/jira/browse/CALCITE-3695">CALCITE-3695</a>, <a href="https://issues.apache.org/jira/browse/CALCITE-3707">CALCITE-3707</a>)
+
+We have also fixed some important bugs:
+* The metadata cache is fixed for rare cases that RelSets are merging (<a href="https://issues.apache.org/jira/browse/CALCITE-2018">CALCITE-2018</a>)
+* The GROUP_ID now returns correct results (<a href="https://issues.apache.org/jira/browse/CALCITE-1824">CALCITE-1824</a>)
+* Correlate row count estimate has been fixed, it is always 1 before (<a href="https://issues.apache.org/jira/browse/CALCITE-3711">CALCITE-3711</a>)
+* The modulus precision inference of DECIMALs has been fixed (<a href="https://issues.apache.org/jira/browse/CALCITE-3435">CALCITE-3435</a>)
+
+Compatibility: This release is tested on Linux, macOS, Microsoft Windows;
+using Oracle JDK 8, 9, 10, 11, 12, 13 and OpenJDK 8, 9, 10, 11, 12, 13;
+Guava versions 19.0 to 27.1-jre; Apache Druid version 0.14.0-incubating;
+other software versions as specified in gradle.properties.
#### Breaking Changes
-* Constructors for `Project`, `TableScan`, `Calc`, `Aggregate` and `Join` introduce new parameter named "hints";
-* Logical `RelNode`'s `create` method need to pass in hints explicitly;
-* `Project` names will not represent in `RelNode` digest anymore;
-* `RexCall`s are default to be normalized in the `RelNode` digest.
+* Constructors for `Project`, `TableScan`, `Calc`, `Aggregate` and `Join` introduce new parameter named "hints" (<a href="https://issues.apache.org/jira/browse/CALCITE-482">CALCITE-482</a>)
+* Logical `RelNode`'s `create` method need to pass in hints explicitly (<a href="https://issues.apache.org/jira/browse/CALCITE-3723">CALCITE-3723</a>)
+* `Project` names will not represent in `RelNode` digest anymore (<a href="https://issues.apache.org/jira/browse/CALCITE-3713">CALCITE-3713</a>)
+* `RexCall`s are default to be normalized in the `RelNode` digest (<a href="https://issues.apache.org/jira/browse/CALCITE-2450">CALCITE-2450</a>)
+* RelBuilder.aggregate now would prune the unused fields from the input, thus the plan may change (<a href="https://issues.apache.org/jira/browse/CALCITE-3763">CALCITE-3763</a>)
+* RelBuilder.scan and sql-to-rel conversion always invoke RelOptTable.toRel now, so there may be some plan changes for the TableScan node if your RelOptTable.toRel returns a physical rel before
