## <a href="https://github.com/apache/calcite/releases/tag/calcite-1.9.0">1.9.0</a> / 2016-09-16
{: #v1-9-0}

This release includes extensions and fixes for the Druid adapter. New features were
added, such as the capability to
<a href="https://issues.apache.org/jira/browse/CALCITE-1357">recognize and translate Timeseries and TopN Druid queries</a>.
Moreover, this release contains multiple bug fixes over the initial implementation of the
adapter. It is worth mentioning that most of these fixes were contributed by Druid developers,
which demonstrates the good reception of the adapter by that community.

We have added new SQL features too, e.g.,
<a href="https://issues.apache.org/jira/browse/CALCITE-1309">support for `LATERAL TABLE`</a>.
There are multiple interesting extensions to the planner rules that should contribute to
obtain better plans, such as
<a href="https://issues.apache.org/jira/browse/CALCITE-1288">avoiding doing the same join twice</a>
in the presence of `COUNT DISTINCT`, or being able to
<a href="https://issues.apache.org/jira/browse/CALCITE-1220">simplify the expressions</a>
in the plan further. In addition, we implemented a rule to
<a href="https://issues.apache.org/jira/browse/CALCITE-1334">convert predicates on `EXTRACT` function calls into date ranges</a>.
The rule is not specific to Druid; however, in principle, it will be useful to identify
filter conditions on the time dimension of Druid data sources.

Finally, the release includes more than thirty bug-fixes, minor enhancements and internal
changes to planner rules and APIs.

Compatibility: This release is tested
on Linux, Mac OS X, Microsoft Windows;
using Oracle JDK 1.7, 1.8;
Guava versions 14.0 to 19.0;
other software versions as specified in `pom.xml`.
