<h2>Asn1 1.4.4.3</h2>
<h3>Fixed errors and malfunctions</h3>
<ul>
<li>A class that was referenced in two steps caused a compiler failure.
It is now corrected.
(Own Id: OTP-5103)<p>
</li>
</ul>
<h3>Improvements and new features</h3>
<ul>
<li>
Optionally make it possible to get the undecoded rest along with
the return value. Compile with option <em>undec_rest</em>.
(Own Id: OTP-5104)<p>
</li>
</ul>
<!--- ----------------------------------------------------------------- --->
<h2>Asn1 1.4.4.2</h2>
<h3>Fixed errors and malfunctions</h3>
<ul>
<li>An error due to unchecked referenced imported type resulted
in missing tag in some table constraint cases. This error is
now corrected. Error occured during decode in
<c>ber_bin optimized</c> version.
(Own Id: OTP-5022)<p>
</li>
</ul>
<!--- ----------------------------------------------------------------- --->
<h2>Asn1 1.4.4.1</h2>
<!--- ----------------------------------------------------------------- --->
<h3>Fixed errors and malfunctions</h3>
<ul>
<li>When a referenced value in another module in turn referenced a
defined value the compilation crashed. This is due to the new
rutines for compilation, that external referencies are resolved
during compilation, and not by the order in which modules are
compiled. This error is now corrected.
(Own Id: OTP-4970)<p>
</li>
</ul>
<h2>Asn1 1.4.4</h2>
<!--- ----------------------------------------------------------------- --->
<h3>Fixed errors and malfunctions</h3>
<ul>
<li>
Functionality for parameterized class is added. Parsing failures on
WithSyntax spec is corrected.
(Own Id: OTP-4893)<p>
</li>
<li>
The failure due to Parameterized Type when parameter is an object
set is corrected.
(Own Id: OTP-4894)<p>
(Aux Id: OTP-4893)
</li>

value reference failed due to parsing conflicts. Now it is
corrected.
(Own Id: OTP-4895)<p>
</li>
<li>
The errorounus comparison of file name and asn1 module name could
cause compilation failure. The situation for this failure is rare,
it requires that other processes modifies the compiled file during
the compilation procedure. It is now fixed.
(Own Id: OTP-4944)
(Aux Id: seq8429)<p>
</li>
<li>
Selective decode was ignored when exclusive decode spec in asn1
configfile was missing. Selective decode failed when the selected
type was the top type. These bugs are now removed.
(Own Id: OTP-4953)
(Aux Id: seq8436)<p>
</li>
<li>
The test interface asn1ct:test/1,2,3 and asn1ct:value/2 failed for
open type and EXTERNAL. The bug is now removed.
(Own Id: OTP-4955)
(Aux Id: seq8438)<p>
</li>
<li>
Two equal functions were generated for two components referencing
the same type when they were picked by the action "parts". The bug
is now fixed.
(Own Id: OTP-4957)
(Aux Id: seq8434)<p>
</li>
</ul>

</ul>
<!--- ----------------------------------------------------------------- --->
<h2>Asn1 1.4.2</h2>
<!--- ----------------------------------------------------------------- --->
<h3>Fixed errors and malfunctions</h3>
<ul>
<li>
When a component in a SEQUENCE is a CHOICE (or reference to a CHOICE)
and the SEQUENCE's component and one of the alternatives in the CHOICE
have identical names, an error may occur if one doesn't use the
'optimized' versions of the compiler. In the older versions (<code>ber,
ber_bin, per, per_bin</code>) one could optionally apply a value of a
component as <code>{ComponentName,Value}</code>, and the generated code
chooses the second element of the tuple. However, a value of a CHOICE
must be applied as a tuple: <code>{AlternativeName,Value}</code>. Thus,
in the rare case described above and if the value to the SEQUENCE's
component is not in a tuple notation the
<code>{AlternativeName,Value}</code> will be peeled off in the SEQUENCE
and the value fed to the CHOICE will only be the <code>Value</code>
part of <code>{AlternativeName,Value}</code>, and the encoder crashes.
The best way to avoid this is to use the optimized version of the
compiler where the unnecessary tuple notation
<code>{ComponentName,Value}</code> no longer is allowed. Since it isn't
possible to solve this bug in the compiler.<br>
(Own Id: OTP-4693)<p>
</li>
</ul>
<!--- ----------------------------------------------------------------- --->
<h3>Improvements and new features</h3>
<ul>
<li>
Exclusive decode is enabled by a compiler option and a configuration
file. It makes it possible to leave parts of an ASN.1 encoded message
undecoded.<br>
(Own Id: OTP-4744)<p>
</li>
</ul>
<!--- ################################################################# --->
<h2>Asn1 1.4.1.1</h2>
<!--- ----------------------------------------------------------------- --->
<h3>Fixed errors and malfunctions</h3>
<ul>
<li>
The documentation about how extensibility is handled is now corrected.<br>
(Own Id: OTP-4663)<p>
</li>
<li>
Function in object now calls the exported function<br>
(Own Id: OTP-4665)<p>
</li>
<li>
Now is tags for ObjectClassFieldType analyzed correctly.
(Own Id: OTP-4666)<p>
</li>
</ul>
<h2>Asn1 1.4.1</h2>
<!--- ----------------------------------------------------------------- --->
<h3>Fixed errors and malfunctions</h3>
<ul>
<li>
Now is the Default value for an ENUMERATED returned as the name from
the NamedList when decoding.
(Own Id: OTP-4633)<p>
</li>
<li>
It was an internal failure when permitted alphabet constraint existed
together with for instance a size constraint. E.g. when a
referenced type is constrained by a size constraint and the defined
type in turn is constrained by a permitted alphabet constraint.<br>
(Own Id: OTP-4559)<p>
</li>
<li>
Record is generated in hrl file for a CHOICE with extension mark
that has an internal SEQUENCE/SET definition.
(Own Id: OTP-4560)<p>
</li>
<li>
Now is the length of a SEQUENCE/SET OF correctly encoded/decoded (PER).
(Own Id: OTP-4590)<p>
</li>
<li>
The problem with unordered decoded terms when a component is a
ObjectClassFieldType has been solved.
(Own Id: OTP-4591)
</li>
</ul>
<h3>Improvements and new features</h3>
<ul>
<li>
More complex definitions with TableConstraints where the SimpleTable
and ComponentRelation are on different levels is now fully
supported. (Own Id: OTP-4631)
</li>
</ul>
<h2>Asn1 1.4</h2>
<!--- ----------------------------------------------------------------- --->
<h3>Fixed errors and malfunctions</h3>
<!--- ----------------------------------------------------------------- --->
<h3>Improvements and new features</h3>
<ul>
<li>
Each generated .erl file have now a function info/0 that returns
information about the used compiler version and options.<br>
(Own Id: OTP-4373)<p>
</li>
<li>
When compiling an ASN.1 module the compiler generates an Erlang module
that is compiled by the Erlang compiler. Earlier it was not possible to
add options to the final step, the Erlang compilation. By adding any
option that is not recognized as a specific ASN.1 option it will be
passed to the final step like: <code>erlc +debug_info
Mymodule.asn</code> or
<code>asn1ct:compile('Mymodule',[debug_info])</code>.<br>
(Own Id: OTP-4491)<p>
</li>
<li>
Earlier one couldn't multi file compile modules that had different
tagdefaul, which now is possible. Equal Type/Value names in different
modules are resolved by renaming (concatenate type name and module
name): If two types with the same name T exist in module A and module B
they will get the new names TA and TB.<br>
(Own Id: OTP-4492)<br>
(Aux Id: OTP-3983)<p>
</li>
<li>
BER: Encode/decode of data have been significantly improved. By use of
the compiler options <code>ber_bin</code> and <code>optimize</code>,
optimized code will be generated and the optimized run-time module will
be used.<br>
(Own Id: OTP-4493)<p>
</li>
</ul>
