Go 1.21 and earlier do not understand this line, causing "go mod vendor" of //go:build go1.22-tagged code that uses this feature to fail. The solution is to include the go/build change to skip over the line in Go 1.22 (making "go mod vendor" from Go 1.22 onward work with this change) and then wait to deploy the cgo change until Go 1.23, at which point Go 1.21 and earlier will be unsupported. For #56378. Fixes #63293.

As always, there are various minor changes and updates to the library,

made with the Go 1 <a href="/doc/go1compat">promise of compatibility</a>
|

There are also various performance improvements, not enumerated here.

The new <a href="/pkg/database/sql/#Null"><code>Null[T]</code></a> type
|

provide a way to scan nullable columns for any column types.

|
|
The <a href="/pkg/reflect/#Value.IsZero"><code>Value.IsZero</code></a>
|
|
method will now return true for a floating-point or complex
|
|
negative zero, and will return true for a struct value if a
|
|
blank field (a field named <code>_</code>) somehow has a
|
|
non-zero value.
|
|
These changes make <code>IsZero</code> consistent with comparing
|
|
a value to zero using the language <code>==</code> operator.
