From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

This is the best summary I could come up with:

One of the interesting improvements to note with GNU Coreutils 9.5 is that the cp, mv, install, cat, and split commands can now read/write a minimum of 256KiB at a time.

Previously there was a 128KiB minimum while this has been doubled in order to enhance the throughput of Coreutils on modern systems.

The throughput with Coreutils 9.5 thanks to this change increases by 10~20% when reading cached files on modern systems.

This default I/O size update was last adjusted a decade ago.

GNU Coreutils 9.5 also has fixed various warnings when interacting with the CIFS file-system, join and uniq better handle multi-byte characters, tail no longer mishandles input from /proc and /sys file-systems, various new options for different commands, SELinux operations during file copy operations are now more efficient, and tail can now follow multiple processes via repeated "--pid" options.

More details on all of the GNU Coreutils 9.5 changes via the release announcement.
