-      TODO: <a href="https://go.dev/issue/50101">https://go.dev/issue/50101</a>: make LookupCNAME consistent between Unix and Windows, document
+      The <code>LookupCNAME</code> function now consistently returns the contents
+      of a <code>CNAME</code> record when one exists. Previously on Unix systems and
+      when using the pure Go resolver, <code>LookupCNAME</code> would return an error
+      if a <code>CNAME</code> record referred to a name that with no <code>A</code>,
+      </code>AAAA</code>, or <code>CNAME</code> record. This change modifies
+      <code>LookupCNAME</code> to match the previous behavior on Windows,
+      allowing allowing <code>LookupCNAME</code> to succeed whenever a
+      <code>CNAME</code> exists.

+      <code>Interface.Flags</code> now includes the new flag <code>FlagRunning</code>,
+      indicating an operationally active interface. An interface which is administratively
+      configured but not active (for example, because the network cable is not connected)
+      will have <code>FlagUp</code> set but not <code>FlagRunning</code>.

+      The new <code>Dialer.ControlContext</code> field contains a callback function
+      similar to the existing <code>Dialer.Control</code> hook, that additionally
+      accepts the dial context as a parameter.
+      <code>Control</code> is ignored when <code>ControlContext</code> is not nil.

+      The Go DNS resolver recognizes the <code>trust-ad</code> resolver option.
+      When <code>options trust-ad</code> is set in <code>resolv.conf</code>,
