The release 0.4.4 includes the following changes (from 0.3.0):

* Bugfixes:
- Draw much less (but still enough
- Fix memory leaks

* API changes:
- scw_view_set_column_foldable():
Add a boolean argument to control the foldability
(previously you couldn't undo setting foldability)
- New signal: "buffer-request"
- New method: scw_view_scroll_to_row():
Scrolls the view to given row (a GtkTreePath)

* Gtk-docs, at last!

(and possibly more, but haven't managed to keep track of all the individual fixes)
