(1) blurry chapters/pages have been replaced
(2) chapters/pages that contain nonmanga related ads were removed
(3) missing chapters/pages were added
(4) duplicate chapters/pages were removed
(5) chapters/pages not in order were corrected

What's the matter on this site ? I receive many notifications for updates but in fact most of the manga have no updates. It's very boring and disagreable...
