BusyBox, the lightweight open-source project that provides several Unix/Linux tools in a single executable for POSIX systems, had its first unstable release in the 1.21 series on Monday.
As shown on
the BusyBox news page there's many changes to the BusyBox 1.21.0 unstable release. BusyBox is still very small on size, but some of the 1.21 changes include improving Debian compatibility of the
ifupdown command, build system improvements, lots of
mdev work, a new
sha3sum applet,
tar command improvements, new sub options supported for
ln, Btrfs/NILFS2/HFSPLUS file-system support in
blkid, and a variety of other work.
The last BusyBox release (1.20.2) happened six months ago.
