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.

The key reason for doing this, as stated in the article:

ultimately they say "the straw that broke the camel's back" to abandon Red Hat Enterprise Linux for their industrial accelerator-control computers was the "-march=x86-64-v2" compiler flag default as "forced obsolescence" for old hardware.

From what I understand, the v2 option requires relatively newer CPU instruction sets, making it incompatible with some older CPUs, even 64 bit ones. I don't know what is gained by using the v2 flag, but I would imagine that it may be something performance-related, by more fully utilizing those newer instruction sets.

Or they're deprecating shit just because, the manteiner must be just a late zoomer that drank the cool aid saying that removing old hw support is the way to go.
