This release ORDER BY analysis for index generation, an ORDER BY-specific rewrite (const-field removal), ORDER BY-specific static checks, table and field alias support, and improved error reporting.

A crash with bigint, datetime, and enum field types was fixed. The covering index generation algorithm was fixed.
