New Symbols and Internal Implementation Changes

If both internal changes and the addition of a new interface has occurred during the same release, both a weak version and an interface version definition should be created. The following example shows the addition of a version definition SUNW_1.2 and an interface change SUNW_1.1.1, which are added during the same release cycle. Both interfaces inherit the original interface SUNW_1.1:

$ cat mapfile
SUNW_1.2 {                   # Release X+1.
        global:
                foo3;
} SUNW_1.1;

SUNW_1.1.1 { } SUNW_1.1;     # Release X+1.

SUNW_1.1 {                   # Release X.
        global:
                foo2;
                foo1;
        local:
                *;
};

The comments for the SUNW_1.1 and SUNW_1.1.1 version definitions indicate that they have both been applied to the same release.
