Changelog
=========
Breaking Changes
----------------
- Changed default required shard copies for table creation and write
operations from ``quorum`` to ``all``.
- Changed the default value of ``number_of_replicas`` from ``1`` to ``0-1``.
Changes
-------
- Expose new setting ``write.wait_for_active_shards`` to allow users to
adjust the required shard copies for write operation to their needs.
- Expose fields for ``information_schema.columns`` and
``information_schema.tables`` so that it conforms to SQL-99 standard.
Fixes
-----
- Added missing table setting ``translog.durability`` which is required and
must be set accordingly so that ``translog.sync_interval`` takes effect.
- Fixed a NPE when querying ``sys.shards`` table.
- Log failed authentication attempts at log level ``WARN``.
