Enhancements:

• Performance optimization for "select *"
• Improved error handling if the data to be inserted doesn't include timestamp
• Performance optimization when there is "IN" clause in both inner and outter query
• Performance optimization when counting disordered data of NCHAR type
• Optimization for interp()

• Crash caused by querying last_row() on a table of 4,000 columns
• Crash caused by "select count(1)"
• Crash caused by tag length exceeding the schema definition
• Crash casued by commiting NONE or NULL to disk

• "Invalid read of size 1" reported by Valgrind
• Duplicate child table name is generating when creating child table automatically
• Incorrect result returned by fill_history + partition by tbname + interval
• Database should not be created if its name exceeds the upper limit
• Other dnodes go to offline if one node is down and restarted
• User should not be created if the password length exceeds upper limit
