-* Improvements in the Drill JDBC driver including inclusion of
-[Javadocs]({{site.baseurl}}/api/1.2/jdbc/) and better application dependency compatibility
-* Enhancements to Avro file formats
- * [Support for complex data types](https://issues.apache.org/jira/browse/DRILL-3565), such as UNION and MAP
- * [Optimized Avro file processing](https://issues.apache.org/jira/browse/DRILL-3720) (block-wise)
-* Partition pruning improvements
-* A number of new [SQL window functions]({{site.baseurl}}/docs/sql-window-functions)
- * NTILE
- * LAG and LEAD
- * FIRST_VALUE and LAST_VALUE
-* [HTTPS support]({{site.baseurl}}/docs/configuring-web-console-and-rest-api-security/) for Web Console operations

-* [Optimized reads]({{site.baseurl}}/docs/querying-hive/#optimizing-reads-of-parquet-backed-tables) of Parquet-backed, Hive tables
-* Read support for the [Parquet INT96 type]({{site.baseurl}}/docs/parquet-format/#about-int96-support) and a new TIMESTAMP_IMPALA type used with the [CONVERT_FROM]({{site.baseurl}}/docs/supported-data-types/#data-types-for-convert_to-and-convert_from-functions) function decodes a timestamp from Hive or Impala.
-* [Parquet metadata caching]({{site.baseurl}}/docs/optimizing-parquet-metadata-reading/) to improve query performance on a large number of files

-## Important Unresolved Issues
-
-* The Drill error message about JSON syntax that appears when Drill cannot find the JDBC driver during configuration of the JDBC storage plugin is misleading. To configure the JDBC plugin, you must put the JDBC driver in the `<drill_installation_directory>/jars/3rdparty` directory. [DRILL-3985](https://issues.apache.org/jira/browse/DRILL-3958)
-* The MySQL TEXT type is not supported. The popular classicmodels database uses the TEXT type, and therefore cannot be used as is until this issue is resolved. [DRILL-3956](https://issues.apache.org/jira/browse/DRILL-3956)

+- Drill implicitly interprets the INT96 timestamp data type in Parquet files.
+- Support for Kerberos authentication between the client and drillbit.
+
