Support for Oracle 10g and 11g: DB Link provides native libraries for these versions of Oracle.

Support for IBM DB2 9.x: New libraries are provided for all ports.

Support for IBM Informix: The former library for Informix version 9, has been compiled against Informix C SDK 3.0. Thus, as stated in the Informix documentation, provides support for Informix versions 5.x to 11.x

Oracle: type BINARY_FLOAT and BINARY_DOUBLE are supported by the libraries for versions 10 and 11.

DB2: The library for version 9.x supports the SQL type DECFLOAT.

This is not a new feature but it lacked documentation in previous versions. DB Link does not provide proper support for long integer SQL types like Informix INT8 or DB2 BIGINT. The size of integer values is limited to the C type long, DB Link does not use the long long (or int64) C type.
