Go 1.20 is the last version that supports Microsoft Windows 7 / 8 / Server 2008 / Server 2012. Starting with Go 1.21, users need to run on Windows 10 or Windows Server 2016 and later.

Go 1.20 also abandoned support for the macOS 10.13 and 10.14 series.

Experimental support for FreeBSD on RISC-V has been introduced.

Go build and go install and other build-related commands now support the "- cover" flag to enable builds with code coverage detection.

Optimize the garbage collector to reduce memory footprint and improve CPU performance by up to 2%.

Preview support for Profile Guided Optimizations (PGO).

On Linux, the linker can choose a dynamic interpreter for glibc or musl.

A new crypto / ecdh package is introduced to provide explicit support for NIST curve and elliptic curve Diffie-Hellman key exchange on Curve25519.
