 19/3/12 started 7.29.0
-- better PNG alpha handling
 - sanity-check PNG read geometry
 - nearest-neighbor interpolation rounds coordinates to nearest instead of 
   rounding down (thanks Nicolas)
 - add dzsave, save in deep zoom format
 - rework im_shrink() as a class
 - remove im_rightshift_size(), just a convenience function now
-- fix write RGBA as JPG (thanks Tobias)
+
+18/6/12 started 7.28.8
+- fixes for centos5 portability
 
 18/6/12 started 7.28.7
 - add vips_flatten() -- flatten RGBA to RGB
 - better alpha handling in PNG load
 - don't save RGBA PNG as CMYK JPG (thanks Tobsn)
 - fix a crash with malformed jpg files (thanks Grigoriy)
+- vipsthumbnail enables sequential mode more and caches lines better
 
 19/4/12 started 7.28.6
 - better resolution unit handling in deprecated im_vips2tiff()
