- added 'datasizes' script that shows you the size allocated
for each symbol, usually answering those "why is does my binary have such a lot of BSS" questions. - stop binpackage looking in /var/spool for package files. - let makewhatis recognize .Sh as heading name - setup, fsck, df: allow >4kB block sizes painlessly - mkfs: new #-of-inodes heuristic that depends on kb, not on blocks; i've run out of inodes on my /usr - asmconv: don't silently truncate .aligns to 16 bytes - ipc* commands for shared memory support
