- Noteworthy changes coreutils in release 7.0 (2008-10-05) [beta]
- New features
chgrp, chmod, chown, chcon, du, rm: now all display linear performance, even when operating on million-entry directories on ext3 and ext4 file systems. Before, they would exhibit O(N^2) performance, due to linear per-entry seek time cost when operating on entries in readdir order. Rm was improved directly, while the others inherit the improvement from the newer version of fts in gnulib.
