Hopefully this will become a standard library in the tradition of gettext. I think this may have been on Slashdot too, but it deserves re-mention. Note that the sources are only available from CVS, some people have been confused about the licensing because the web site only has binaries. It almost requires 3D acceleration to be fast enough, but it's pretty cool. For now it's a fun standalone application.
Icons now use bilinear scaling for higher quality scaled images.
Zooming in the icon view now shows more information at higher zoom levels. What information is shown in what order is customizable. The appearance of the side panel and the way meta-views display there is being reworked, but is not done yet. Nautilus can now properly embed Bonobo controls and subdocuments. The usual bunch of bug fixes.
