JDBC Driver JAR Files - Mailing list pgsql-jdbc

In the default installation of PostgreSQL that comes with RedHat Linux,
there are two JDBC JAR files.  These are

    jdbc7.0-1.1.jar
and
    jdbc7.0-1.2.jar

Does anyone know what the difference is (besides the obvious release level)?
Which is the 'better' one to use?

Thanks in advance.
