0.8.17: 2004-Aug-11
* Improved compiler output: duplicate #includes eliminated.
* Win32 portability fixes.
* More compatibility with C++ or non-GCC compilers.
0.8.16: 2004-Jul-22
* Fixed application-level problem in SET OF/SEQUENCE OF array cleanup.
(Severity: medium, Security impact: low)
* Improved asn_GT2time() and added asn_time2{GT,UT}() functions.
* BIT STRING pretty-printing.
0.8.15: 2004-Jul-20
* Fixed parser: memory leak in free_struct code for SET OF/SEQUENCE OF.
(Severity: high, Security impact: medium)
* Fixed parser: invalid memory reference in code constructing tags.
(Test case 48) (Severity: high, Security impact: medium)
When encoding data for certain ASN.1 specifications containing
explicit tags, the tag is always written incorrectly due to
incorrect memory reference. The encoding will almost always produce
unparseable data and might well reference unmapped region so program
would produce segmentation violation. Fortunately, memory is
read, not written, so remote exploits cannot execute arbitrary
code and triggering unmapped memory reference is highly unlikely
even it attacker knows the code (basically, the compiler should place
asn1_DEF_... right before the end of the mapped memory region, which
is extremely rare).
* Improved INTEGER type printing.
0.8.14: 2004-Jun-30
* Fixed compiler: extensibility of CHOICE and SET type has not been
taken into account during table construction.
(Test case 47) (Severity: high, Security impact: low)
0.8.13: 2004-Jun-29
* Fixed compiler: the skip values for IMPLICIT tagging were broken
in some complex cases where one type is defined using another.
(Test case 46) (Severity: medium, Security impact: low).
* Added -fknown-extern-type command line parameter to asn1c.
* Removed -N command line flag and underlying functionality
to honor KISS principle.
0.8.12: 2004-Jun-17
* RELATIVE-OID and OBJECT IDENTIFIER encoders/decoders are not bound
anymore to an integer type of specific size (unsigned long). The
size of an integer must be provided explicitly.
* SEQUENCE BER decoder fixed again for complex CHOICE case
(Test case 44) (Severity: medium, Security impact: low).
0.8.11: 2004-Jun-05
* Enforced stricter conformance with C standards.
* SEQUENCE BER decoder is now equipped with the sorted map
in case of complex CHOICE descendants. Test case 44 created.
0.8.10: 2004-Jun-02
* Added const qualifier where necessary.
* Changed position of outmost_tag fetcher within asn1_TYPE_descriptor_t
0.8.9: 2004-May-26
* Added *_{get|set}_arcs_*() functions for OBJECT IDENTIFIER
and RELATIVE-OID, together with test cases.
0.8.8: 2004-May-09
* Introduced subtype constraints support (incomplete!).
* Fixed compiler. If the last member of the SEQUENCE is OPTIONAL
and absent in the encoding, and the type is extensible (...) or
EXTENSIBILITY IMPLIED flag is set, then the structure could not
be correctly decoded. (Severity: high, Security impact: low).
* Compiler: fixed recursive ASN.1 types inclusion (Severity: low,
Security impact: none).
* Parser: IMPORTS/FROM fixes, now allowing multiple sections.
* Code compiled and checked on PowerPC (@MacOS X). No major portability
issues experienced.
0.8.7: 2004-Apr-11 T-version-0-8-7
* Fixed SEQUENCE BER decoder: if the last member of the SEQUENCE is
OPTIONAL and absent in the encoding, RC_FAIL was returned instead
of RC_OK (Severity: high, Security impact: low).
* Added test case to check the above problem.
* Added test case to check -fnative-integers mode.
0.8.6: 2004-Apr-03 T-version-0-8-6
* Fixed compiler output for embedded ASN.1 structures.
0.8.5: 2004-Mar-28 T-version-0-8-5
* Fixed ber_tlv_length() computation problem (Severity: blocker,
Security impact: none).
Reported by <>
0.8.4: 2004-Mar-22
* Removed RC_ITAG enumeration element from BER decoder.
This return code did not have much practical value.
0.8.3: 2004-Mar-14 T-version-0-8-3
* Fixed SET::BER decoder: restart after reaching a buffer boundary
weas broken (Severity: blocker, Security impact: low).
* Fixed OCTET STRING::BER decoder: restart after reaching a buffer
boundary was broken (Severity: blocker, Security impact: low).
Reported by <>
* Added test cases to check decoders restartability.
* Slightly more general INTEGER2long decoder.
* Allowed nested /* C-type */ comments, as per X.680:2002.
0.8.2: 2004-Mar-01 T-version-0-8-2
* Fixed SEQUENCE BER decoder: an OPTIONAL element was required, where
should not have been (Severity: major; Security impact: low).
* Fixed print_struct pointer inheritance.
* Added -fno-c99 and -funnamed-unions
0.8.1: 2004-Feb-22
* -R switch to asn1c: Omit support code, compile only the tables.
* Introduced NativeInteger pseudotype.
* Corrected the informal print_struct()'s output format.
0.8.0: 2004-Feb-03 T-version-0-8-0
* Some documentation is created (a .pdf and a short manual page).
* Last touches to the code.
0.7.9: 2004-Feb-01 T-version-0-7-9
* Human readable printing support.
* Support for implicit (standard) constraints.
0.7.8: 2004-Jan-31
* SET now rejects duplicate fields in the data stream.
0.7.7: 2004-Jan-25
* Added types: GeneralizedTime and UTCTime.
0.7.6: 2004-Jan-24 T-version-0-7-6
* DER encoding of a SET OF now involves dynamic sorting.
0.7.5: 2004-Jan-24 T-version-0-7-5
* DER encoding of a SET with untagged CHOICE
now involves dynamic sorting.
0.7.0: 2004-Jan-19 T-version-0-7-0
* A bunch of DER encoders is implemented.
0.6.6: 2004-Jan-11
* Implemented CHOICE decoder.
* Implemented destructors support.
0.6.5: 2004-Jan-03
* Implemented SET decoder.
* Implemented SET OF and SEQUENCE OF decoders.
0.6.4: 2003-Dec-31
* Implemented BOOLEAN, NULL, ENUMERATED decoders.
* Implemented OCTET STRING decoder.
* Implemented BIT STRING decoder.
0.6: 2003-Dec-30
* First decoding of a BER-encoded structure!
0.5: 2003-Dec-28
* Framework and most of the compiler backbone coding done.

* Programming started.
