          <p>[ftpc] Add a config option to specify a 
	  <seealso marker="ftp#dtimeout">data connect timeout</seealso>.
	  That is how long the ftp client will wait for the server to connect
	  to the data socket. If this timeout occurs, an error will be 
	  returned to the caller and the ftp client process will be 
	  terminated. </p>

          <p>[httpc] Wrong Host header in IPv6 HTTP requests.
	  When a URI with a IPv6 host is parsed, the brackets that encapsulates
	  the address part is removed. This value is then supplied as the host 
	  header. This can cause problems with some servers.
	  A workaround for this is to use headers_as_is and provide the host
	  header with the requst call. 
	  To solve this a new option has been added, 
	  <seealso marker="httpc#ipv6_host_with_brackets">ipv6_host_with_brackets</seealso>. 
	  This option specifies if the host value of the host header shall 
	  include the brackets or not. By default, it does not (as before).

	    [httpc] If a request times out (not connect timeout), the

	    the manager process. For this reason, the manager did not
	    clean up the request table., resulting in a memory leak.
	    Also the manager did not create a monitor for the
	    handler, so in an unforseen handler crash, this could

	  <p>[httpc] - Memory leak plugged. 
            The profile manager never cleaned up in its handler database. 
            This meant that with each new request handler, another entry 
            was created that was never deleted. Eventually the request
            id counter (used as a key) would wrap, but the machine would 
            most likely run out of memory before that happened.</p>

	      <item>
		<p>The <c>erl_script_timeout</c> config option is ducumented
                  as a number of seconds. But when parsing the config, in the
                  new format (not a config file), it was handled as if in

          <p>[httpc] Fix bug crafting Host header when port is not 80. </p>
          <p>The host header should include the port number as well as the 
            host name when making a request to a server listening on a port 
            other than the HTTP default of 80. Currently, only the host

	  <p>[httpc|httpd] http_chunk data handling/passing improvement. </p> 
          <p>This is a modification to the http_chunk module to forward any 
            full chunk received, regardless of whether the size field for the 
            following chunk has been received yet.  This allows http_chunk to 
            be used in situations where a long term HTTP connection is used to 
            send periodic status updates as individual chunks.  Previously a 
            given chunk would not be forwarded to the client process until the 
            size for the next chunk had been read which rendered the module 
            difficult to use for the scenario described. </p>

          <p>[httpc] Several more or less critical fixes:</p>
          <p>
            <list type="bulleted">
	      <item>
		<p>Initial call between the httpc manager and request 
                  handler was synchronous. </p>
		<p>When the manager starts a new request handler, 
                  this is no longer a synchronous operation. Previously, 
                  the new request handler made the connection to the 
                  server and issuing of the first request (the reason 
                  for starting it) in the gen_server init function. 
                  If the connection for some reason "took some time", 
                  the manager hanged, leaving all other activities by 
                  that manager also hanging. </p>

	    <p>[httpd] - When starting inets (the web-server) and supplying 
              a descriptor on the command line 
              (example: erl -httpd_8888 &lt;descriptor&gt;) 
              it is now possible to specify which ip-family to use:
              <c>inet | inet6 | inet6fb4</c>. </p>
            <p>Example: erl -httpd_8888 10|inet6</p>
            <p>When starting the web-server either using a file with 
              property list (the proplist_file) or a an property list,
              using the ipfamily option: 
              <c>{ipfamily, inet | inet6 | inet6fb4}</c>. </p>
            <p>Finally, when starting the web-server using the classical
              apache-style config file, the <c>BindAddress</c> directive
              has been augmented to allow the specification of the 
              IpFamily: <c>BindAddress blirk.ericsson.se|inet</c></p>
            <p>Default is <c>inet6fb4</c> which emulates the 
              behaviour of the previous version. </p>

          <item>
            <p>[httpc] Added support for web services using only basic auth,
              with a token as the user part and no password part.</p>

	  <item>
	    <p>[httpc] - Bind HTTP client to IP-addr. It is now possible 
              to specify an alternate ip-address and port to be used when 
              the client connects to the server. </p>
	    <p>As a side-effect of this, the option <c>ipv6</c> has been 
              removed and replaced by the <c>ipfamily</c> option. </p>
