### New structs package

The new [structs] package provides
types for struct fields that modify properties of
the containing struct type such as memory layout.

In this release, the only such type is
[`HostLayout`](/pkg/structs#HostLayout)
which indicates that a structure with a field of that
type has a layout that conforms to host platform

## Notable Packages

- The [x/telemetry/counter](https://pkg.go.dev/golang.org/x/telemetry/counter)
  package provides a library for instrumenting programs with counters and stack
  reports.
- The [x/telemetry/upload](https://pkg.go.dev/golang.org/x/telemetry/upload)
  package provides a hook for Go toolchain programs to upload telemetry data,
  if the user has opted in to telemetry uploading.

// Package gover implements support for Go toolchain versions like 1.21.0 and 1.21rc1.
// (For historical reasons, Go does not use semver for its toolchains.)
// This package provides the same basic analysis that golang.org/x/mod/semver does for semver.
// It also provides some helpers for extracting versions from go.mod files
// and for dealing with module.Versions that may use Go versions or semver
// depending on the module path.

// The computed hash values depend only on the initial seed and
// the sequence of bytes provided to the Hash object, not on the way
// in which the bytes are provided. For example, the three sequences
//
//	h.Write([]byte{'f','o','o'})
//	h.WriteByte('f'); h.WriteByte('o'); h.WriteByte('o')
//	h.WriteString("foo")
//
// all have the same effect.
