Go 1.20 released
Wednesday February 1, 2023. 10:33 PM , from LWN.net
Version 1.20 of the Go language
has been released. We’re particularly excited to launch a preview of profile-guided optimization (PGO), which enables the compiler to perform application- and workload-specific optimizations based on run-time profile information. Providing a profile to go build enables the compiler to speed up typical applications by around 3–4%, and we expect future releases to benefit even more from PGO. Since this is a preview release of PGO support, we encourage folks to try it out, but there are still rough edges which may preclude production use. Go 1.20 also includes a handful of language changes, many improvements to tooling and the library, and better overall performance.
