<p>[ftpc] - Start of the FTP client has been changed in
the following way: </p>
<list type="bulleted">
<item>
<p>It is now also possible to start a standalone FTP client
process using the re-introduced
<seealso marker="ftp#open">ftp:open</seealso>
function. </p>
<p>This is an alternative to starting the client using the
<seealso marker="ftp#service_start">inets service framework</seealso>. </p>
<p>The old <c>ftp:open/1</c>, undocumented, function,
caused the client to be hooken into the inets service
supervision framework. This is <em>no</em> longer the
case. </p>
<p>*** POTENTIAL INCOMPATIBILITY ***</p>
</item>
<item>
<p>Previously, the FTP client attempted to use IPv6,
unless otherwise instructed (the <c>ip_v6_disabled</c>
flag), and only used IPv4 if this did not work.
This has now been <em>changed</em>. </p>
<p>A new option,
<seealso marker="ftp#ipfamily">ipfamily</seealso>,
has been introduced, with the default value
<c>inet</c> (IPv4). </p>

<p>[ftpc] - The
<seealso marker="ftp#ls2">ls/2</seealso> function (LIST command)
and the
<seealso marker="ftp#nlist2">nlist/2</seealso> function
(NLST command)
with wildcards did
not work properly. </p>
<p>These functions is documented as working on directories, but
this is actually not according the standard. The LIST and NLST
commands are specified to operate on a directory or other
group of files, or a file.</p>
<p>Previously, an attempt was made to check if the listing
returned by the server was actually an error message. This
was done by changing remote directory (cd) into the
(assumed) "directory". This may work if Pathname was actually
a directory, but as this is not always the case, this test
does not work. Instead, we now return the actual server
result and leave the interpretation to the caller. </p>

<p>[httpc] - Raise condition.
When http:request is called and httpc_manager selects a session
where there's already a pending request, then the connection
handler for that session effectively resets its parser, readying
it for the response to the second request. But if there are still
some inbound packets for the response to the first request, things
get confused.</p>

<p>[httpd] - When starting inets (the web-server) and supplying
a descriptor on the command line
(example: erl -httpd_8888 <descriptor>)
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>

[tftp] If a callback (which performs the file access in
the TFTP server) takes too long time (more than the
double TFTP timeout), the server will abort the
connection and send an error reply to the client. This
implies that the server will release resources attached
to the connection faster than before. The server simply
assumes that the client has given up.</p>
<p>
[tftp] If the TFTP server receives yet another request
from the same client (same host and port) while it
already has an active connection to the client, it will
simply ignore the new request if the request is equal
with the first one (same filename and options). This
implies that the (new) client will be served by the
already ongoing connection on the server side. By not
setting up yet another connection, in parallel with the
ongoing one, the server will consumer lesser resources.</p>
<p>
[tftp] netascii mode is now supported when the
client/server has native ascii support (Windows). The new
optional parameter native_ascii in the tftp_binary and
tftp_file callback modules can be used to override the
default behavior.</p>
<p>
[tftp] Yet another callback module has been added in
order to allow customized handling of error, warning and
info messages. See the new configuration parameter,
logger.</p>
<p>
[tftp] Yet another configuration parameter, max_retries,
has been added in order to control the number of times a
packet can be resent. The default is 5.</p>
<p>
[tftp] tftp:info/1 and tftp:change_config/2 can now be
applied to all daemons or all servers in one command
without bothering about their process identifiers.</p>

The Inets application now has to be explicitly started
and stopped i.e. it will not automatically be started as
a temporary application as it did before. Although a
practical feature when testing things in the shell it is
not desirable that people take advantage of this and not
start the Inets application in a correct way in their
products. Added functions to the Inets API that call
application:start/stop.</p>
