The following package has been upgraded in the Cygwin distribution:

* cpuid 20211114

The program displays detailed information about the CPU(s) gathered from
the CPUID instruction, and also determines the exact model of CPU(s).

Whereas /proc/cpuinfo is like an abstract of the features important to
Linux in a system, cpuid is a standalone utility which writes a paper
expounding on every feature in each CPU's architecture and what it can
do, at about the one line per bit level.

It is updated and released frequently and appears current with Intel and
AMD information and supports other vendors' chips.

See the project home page for more information:
