There's a new 'capture option', 'in-depth
capture':
which enables you to capture ... linked
pages [to a] deeper level.
'Depth to follow links' option enables us to capture Web-site
entirely.
'Filter' option enables us to restrict URLs by domain, directory
and string.
After completing captures, all pages are linked each other.
Source: the
in-depth capture section on the feature page.
There's another new feature I find interesting,
auto-generating a site map when the in-depth capture technique
is used.
Coming in 0.18.0: combining pages, an
example
of which is here.
