Enhancements:
- Adjusted the behavior of limit/slimit with group by to be compatible with 2.x
- Performance improvement for count(1)
Fixed bugs:
- non-root user query information_schema.ins_dnodes caused client crash
- group by tag with limit doesn't work
- last() result is not correct when queryPolicy is set to 3
- filter for non-key timestamp caused too many window
- Errors reported in writing with schemaless
- Stream doens't work after the table schema was altered
- Group by doesn't return expected result
- Improper error message was reported when using order by
