<p>
  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>
  in mind.
  There are also various performance improvements, not enumerated here.

    <p><!-- https://go.dev/issue/60370, CL 501700 -->
      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.

<dl id="reflect"><dt><a href="/pkg/reflect/">reflect</a></dt>
  <dd>
    <p><!-- https://go.dev/issue/61827, CL 517777 -->
      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.
