Fix a rare bug where rows containing only null values are not returned
to the client. This only occurs when an entire result page contains only
null values. The only known case is a query over an ORC encoded Hive table
that does not perform any transformation of the data.
Fix incorrect results when performing comparisons between values of approximate
data types (REAL, DOUBLE) and columns of certain exact numeric types
(INTEGER, BIGINT, DECIMAL).
Add initial support for CROSSJOIN against LATERAL derived tables.
Add support for VARBINARY concatenation.
Add Thrift Connector that makes it possible to use Presto with
external systems without the need to implement a custom connector.
Add experimental /v1/resourceGroupState REST endpoint on coordinator.
Fix skipping short decimal values in the optimized Parquet reader
when they are backed by the int32 or int64 types.
Ignore partition bucketing if table is not bucketed. This allows dropping
the bucketing from table metadata but leaving it for old partitions.
Improve error message for Hive partitions dropped during execution.
The optimized RCFile writer is enabled by default, but can be disabled
with the hive.rcfile-optimized-writer.enabled config option.
The writer supports validation which reads back the entire file after
writing. Validation is disabled by default, but can be enabled with the
hive.rcfile.writer.validate config option.
Add support for INSERT.
Add support for pushdown of non-equality predicates on clustering keys.
JDBC Driver Changes
Add support for authenticating using Kerberos.
Allow configuring SSL/TLS and Kerberos properties on a per-connection basis.

Add support for executing queries using an HTTP proxy.
