Internal Implementation Changes

Any compatible new release of the shared object that consists of an update to the implementation of the object -- for example, a bug fix or performance improvement -- should be accompanied by a weak version definition. This new version definition should inherit the latest version definition present at the time the update occurred.

The following mapfile example generates a weak version definition SUNW_1.1.1. This new interface indicates that the internal changes were made to the implementation offered by the previous interface SUNW_1.1:

$ cat mapfile
SUNW_1.1.1 { } SUNW_1.1;     # Release X+1.

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