Remove ReflectiveSchema.name field, now that https://github.com/julianhyde/optiq/issues/214 is fixed.
Allow schema-qualified calls to user-defined aggregate functions.
Fix https://github.com/julianhyde/optiq/issues/245, "Off-by-one translation of ON clause of JOIN".
Fetch and Limit RexNodes are ignored when creating a new SqlRel object from existing SqlRel.

Cleanup by Julian Hyde:
* Make SqlToRelConverterTest flatten & decorrelate by default.
* Fix resulting asserts in the copy methods of various RelNode sub-types.
* Add tests that combine decorrelation with ORDER BY, LIMIT, OFFSET.
Update history.
Upgrade to linq4j-0.2.

Adapt newest linq4j by avoiding sharing of "unboxed values".

Use better names for local variables: use field index to simplify debugging.
Up minor version ahead of release. For the version sanity-check, redefine sanity.
[maven-release-plugin] prepare release optiq-parent-0.6
[maven-release-plugin] prepare for next development iteration
Fix https://github.com/julianhyde/optiq/issues/205, "Suspicious map.get in VolcanoPlanner.reregister".
Fix https://github.com/julianhyde/optiq/issues/238, "Add adapter that generates TPC-H data".

Added TpchSchemaFactory. TPC-H tests are run if -Doptiq.test.slow=true is specified.
Some TPC-H columns have type DATE.
Remove some obsolete classes.
Remove unused constructor parameter.
Fix https://github.com/julianhyde/optiq/issues/242, "SplunkAdapterTest fails".

The Splunk adapter had been broken by various changes, including the factoring out of Avatica JDBC and removing the schema parent from a table. SplunkAdapterTest now succeeds, and can be run as part of the regular suite if you specify -Doptiq.test.splunk=true.
SplunkAdapterTest now uses the same Foodmart database as JdbcTest.

Begin support for a mock Splunk connection; when it is a complete, you will be able to run the Splunk test suite without Splunk being present.
Implement scalar sub-query in SELECT clause.
Fix https://github.com/julianhyde/optiq/issues/175, "Modify Schema SPI to allow caching".

Added "cache" attribute of Schema JSON element; add method contentsHaveChangedSince to Schema SPI (breaking change, if you've written a schema that does not extend AbstractSchema); big rework of how OptiqSchema builds maps of tables, functions and sub-schemas and how it handles case-insensitive matches.
Tweak parallelism of optiq-plus test suite.
Fix https://github.com/julianhyde/optiq/issues/37, "Document JSON model file format"
