The backend module appmon_info.erl is moved from appmon
application to runtime_tools. This allows appmon to be
run from a remote erlang node towards a target node which
does not have appmon (and its dependencies) installed, as
long as runtime_tools is installed there.</p>

Encoding SEQUENCEs with multiple extension addition
groups with optional values could fail (depending both on
the specification and whether all values were provided).</p>

<p>The options for the ASN.1 compiler has been
drastically simplified. The backend is chosen by using
<c>ber</c>, <c>per</c>, or <c>uper</c>. The options
<c>optimize</c>, <c>nif</c>, and <c>driver</c> are no
longer needed. The old options will still work, but will
issue a warning.</p>
<p>Another change is that generated <c>encode/2</c>
function will always return a binary (some backends used
to return an iolist).</p>

The ASN.1 compiler generates faster decode functions for
PER and UPER. Some minor improvements have also been made
for PER/UPER encoding, and to the BER backend.</p>
<p>

</item>
<item>
<p>The ASN.1 compiler will now always include necessary
run-time functions in the generated Erlang modules
(except for <c>asn1rt_nif</c> which is still neeeded). If
the option '<c>inline</c>' is used the ASN.1 compiler
will generate a warning. But if
'<c>{inline,OutputFile}</c>' is use, the ASN.1 compiler
will refuse to compile the file. (Use a <c>.set.asn</c>
file if you need to remove the output file.)</p>
<p>The '<c>BIT STRING</c>' type will now be decoded as
Erlang bitstrings by default. Use the new
<c>legacy_bit_string</c> option to encode as lists of
ones and zeroes. (The <c>compact_bit_string</c> option
still works as before.)</p>
<p>Open types are now always returned as binaries (when
there is no information allowing them to be decoded).</p>

If a busy test case generated lots of error messages,
cth_log_redirect:post_end_per_testcase would crash with a
timeout while waiting for the error logger to finish
handling all error reports. The default timer was 5
seconds. This has now been extended to 5 minutes.</p>

<p>When a test case failed because of a timetrap time
out, the <c>Config</c> data for the case was lost in the
following call to <c>end_per_testcase/2</c>, and also in
calls to the CT Hook function
<c>post_end_per_testcase/4</c>. This problem has been
solved and the <c>Config</c> data is now correctly passed
to the above functions after a timetrap timeout
failure.</p>

<p>In test_server, the same process would supervise the
currently running test case and be group leader (and IO
server) for the test case. Furthermore, when running
parallel test cases, new temporary supervisor/group
leader processes were spawned and the process that was
group leader for sequential test cases would not be
active. That would lead to several problems:</p>
<p>* Processes started by init_per_suite will inherit the
group leader of the init_per_suite process (and that
group leader would not process IO requests when parallel
test cases was running). If later a parallel test case
caused such a processto print using (for example)
io:format/2, the calling would hang.</p>
<p>* Similarly, if a process was spawned from a parallel
test case, it would inherit the temporary group leader
for that parallel test case. If that spawned process
later - when the group of parallel tests have finished -
attempted to print something, its group leader would be
dead and there would be <c>badarg</c> exception.</p>
<p>Those problems have been solved by having group
leaders separate from the processes that supervises the
test cases, and keeping temporary group leader process
for parallel test cases alive until no more process in
the system use them as group leaders.</p>
<p>Also, a new <c>unexpected_io.log</c> log file
(reachable from the summary page of each test suite) has
been introduced. All unexpected IO will be printed into
it(for example, IO to a group leader for a parallel test
case that has finished).</p>

Some bugfixes in <c>ct_snmp:</c></p>
<p>
<list> <item> ct_snmp will now use the value of the
'agent_vsns' config variable when setting the 'variables'
parameter to snmp application agent configuration.
Earlier this had to be done separately - i.e. the
supported versions had to be specified twice. </item>
<item> Snmp application failed to write notify.conf since
ct_snmp gave the notify type as a string instead of an
atom. This has been corrected. </item> </list></p>

Some bugfixes in <c>ct_snmp</c>:</p>
<p>
<list> <item> Functions <c>register_users/2</c>,
<c>register_agents/2</c> and <c>register_usm_users/2</c>,
and the corresponding <c>unregister_*/1</c> functions
were not executable. These are corrected/rewritten.
</item> <item> Function <c>update_usm_users/2</c> is
removed, and an unregister function is added instead.
Update can now be done with unregister_usm_users and then
register_usm_users. </item> <item> Functions
<c>unregister_*/2</c> are added, so specific
users/agents/usm users can be unregistered. </item>
<item> Function <c>unload_mibs/1</c> is added for
completeness. </item> <item> Overriding configuration
files did not work, since the files were written in
priv_dir instead of in the configuration dir
(priv_dir/conf). This has been corrected. </item> <item>
Arguments to <c>register_usm_users/2</c> were faulty
documented. This has been corrected. </item> </list></p>

<p>It is now possible to let a test specification include
other test specifications. Included specs can either be
joined with the source spec (and all other joined specs),
resulting in one single test run, or they can be executed
in separate test runs. Also, a start flag/option,
<c>join_specs</c>, has been introduced, to be used in
combination with the <c>spec</c> option. With
<c>join_specs</c>, Common Test can be told to either join
multiple test specifications, or run them separately.
Without <c>join_specs</c>, the latter behaviour is
default. Note that this is a change compared to earlier
versions of Common Test, where specifications could only
be joined. More information can be found in the Running
Tests chapter in the User's Guide (see the Test
Specifications section).</p>

binaries and strings instead of binary_to_list and
