A new connection option, prefetch, allows applications to scroll through large query result sets, N records at a time. See Connector/ODBC Connection Parameters for details.

The SQLTables() function did not return the catalog correctly if the wildcard or SQL_ALL_CATALOGS was used. (Bug #13914518)

The fraction member in SQL_TIMESTAMP_STRUCT was always set to 0 when a timestamp was retrieved using SQLGetData(). The fix causes the fraction member to be correctly set, with a value representing nanoseconds. This issue did not occur when a result was retrieved as a string (SQLGetData() with SQL_C_CHAR). (Bug #12767740, Bug #60646)

Fractional seconds part of timestamp was ignored in prepared statements that use SQLBindParameter and SQL_C_TIMESTAMP type. For example, a prepared query comparing two timestamp values that only differed in the fractional part would consider the values identical. (Bug #12767761, Bug #60648)

On Windows platforms, some memory was leaked on each connection attempt due to an incorrect response to a SQLGetDiagRec() call. (Bug #11766029, Bug #59059)
