主要更新内容如下：
Fixed an issue which prevents java client from running explain
statements.
Fixed an issue which caused `current_timestamp` as part of a generated
expression to not work correctly.
This fix will only affect new tables. Tables which already contain a
generated column which uses `current_timestamp` will need to be recreated.
Improved error handling when grouping by invalid data types.
Fixed an issue when ordering by a function on a joined query.
Fixed an issue which could lead to wrong Error messages due to a
race condition.
Fix: Arrays of geo_point can be used in insert/update
statements as literals as well as bind arguments.
Fixed a read isolation issue which could cause joins involving
system and blob tables to return inconsistent results.
On Hunspell dictionary configuration, the parameter
indices.analysis.hunspell.dictionary.location has been removed and
s always used.
Fixed a bug that prevented join and sort on blob tables.
Adapted behaviour of stats.enabled, stats.jobs_log_size and stats.operations_log_size settings
to match behaviour of other cluster wide settings like for example minimum_master_nodes.
Fix: Do not fetch table stats when node is not fully available yet.
This could have led to NullPointerExceptions during long recovery
process on node start.
Fixed an issue which prevented running join queries on empty partitioned
tables.
Fix: the ``hostname`` column of the ``sys.nodes`` table returns a hostname
instead of an IP address.
Fixed an issue that caused select statements to get stuck if used as part of
a bulk request. Now a proper error is raised.
Updated Elasticsearch to 2.3.4
Fix: the ``within`` scalar function now allows querying geo_shapes within
geo_shapes.
