+
+This release comes two months after 1.20.0. It includes more than 100 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.
+
+* Added support for implicit type coercion in various contexts
+(<a
href="https://issues.apache.org/jira/browse/CALCITE-2302";>CALCITE-2302</a>).
+* Pig Latin scrips can now be transformed into algebraic plans
+(<a
href="https://issues.apache.org/jira/browse/CALCITE-3122";>CALCITE-3122</a>).
+* The basic features of MATCH_RECOGNIZE are now implemented
+(<a
href="https://issues.apache.org/jira/browse/CALCITE-1935";>CALCITE-1935</a>).
+* Correlated ANY/SOME/ALL subqueries are now supported
+(<a
href="https://issues.apache.org/jira/browse/CALCITE-3031";>CALCITE-3031</a>).
+* The parser has been enhanced to handle ROW, ARRAY, and COLLECTION types
+(<a href="https://issues.apache.org/jira/browse/CALCITE-3250";>CALCITE-3250</a>,
+<a href="https://issues.apache.org/jira/browse/CALCITE-3233";>CALCITE-3233</a>,
+<a href="https://issues.apache.org/jira/browse/CALCITE-3231";>CALCITE-3231</a>).
+* New join algorithms for the Enumeberable convention have been added
+(<a href="https://issues.apache.org/jira/browse/CALCITE-2979";>CALCITE-2979</a>,
+ <a href="https://issues.apache.org/jira/browse/CALCITE-2973";>CALCITE-2973</a>
+ <a
href="https://issues.apache.org/jira/browse/CALCITE-3284";>CALCITE-3284</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 `pom.xml`.
#### Breaking Changes
-* core parser config.fmpp#dataTypeParserMethods should return `SqlTypeNameSpec`
+* Core parser config.fmpp#dataTypeParserMethods should return `SqlTypeNameSpec`
instead of `SqlIdentifier`.
+* The description of converter rules has slightly changed (
+ <a
href="https://issues.apache.org/jira/browse/CALCITE-3115";>CALCITE-3115</a>).
+ In some rare cases this may lead to a `Rule description ... is not valid`
+ exception. The exception can easily disappear by changing the name of the
+ `Convention` which causes the problem.
