  1. Add (long overdue) support for RIGHT and FULL OUTER JOIN<\/a>.\n<\/li>\n
  2. Add new binary comparison operators IS NOT DISTINCT FROM<\/a> and IS DISTINCT FROM<\/a>
    \n that are equivalent to IS and IS NOT, respective, for compatibility with
    \n PostgreSQL and SQL standards.\n<\/li>\n
  3. Add a new return code (value \"3\") from the sqlite3_vtab_distinct()<\/a>
    \n interface that indicates a query that has both DISTINCT and ORDER BY
    \n clauses.\n<\/li>\n
  4. Added the sqlite3_db_name()<\/a> interface.\n<\/li>\n
  5. The unix os interface resolves all symbolic links in database
    \n filenames to create a canonical name for the database before the
    \n file is opened.\n<\/li>\n
  6. Defer materializing views until the materialization
    \n is actually needed, thus avoiding unnecessary work if the materialization turns
    \n out to never be used.\n<\/li>\n
  7. The HAVING clause<\/a> of a SELECT statement<\/a> is now allowed on any aggregate query,
    \n even queries that do not have a     GROUP BY clause<\/a>.\n<\/li>\n
  8. Many microoptimizations<\/a> collectively reduce CPU cycles by about 2.3%.\n
