Version 1.2 (released 2007-12-10)
- Update gnulib files.

Version 1.1 (released 2007-08-31)
- Fix bug that made asn1_check_version believe that 1.0 is older than 0.3.10.

Version 1.0 (released 2007-08-31)
- The self-tests, command line tools and build infrastructure have
  been re-licensed from GPLv2 to GPLv3.

Version 0.3.10 (released 2007-05-25)
- Update gnulib files.

Version 0.3.9 (released 2007-03-02)
- In generated code, config.h is pulled in if HAVE_CONFIG_H.

  I push my changes to <http://repo.or.cz/w/libtasn1.git>.
- Autoconf 2.61 and automake 1.10 is required.

Version 0.3.8 (released 2006-11-16)
- Fix reading of binary files in asn1Decoding, for Windows.

Version 0.3.7 (released 2006-10-19)
- When asn1_der_coding encoded a TYPE_NULL and the output buffer is
  NULL, it would not increment the counter properly, so the size of
  the required buffer would be off by one.  Fixed.  Reported by
  Stephen Wrobleski <steve@localtoast.org>.
- Fix configure to respect user-definable flags.  Reported by "Diego
  'Flameeyes' Pettenò" <flameeyes@gentoo.org>.
- The --help and --version outputs from the tools have been improved.

Version 0.3.6 (released 2006-08-13)
- Fix man pages to use \- instead of - for negative signs (as in "-1").
- Add -I's when building in src/, so that unistd.h etc is found on
  systems that doesn't have them.
- Valgrind isn't used for cross-compilation by default, and there is
  also --disable-valgrind-tests to unconditionally disable it.
- Valgrind is invoked without parameters, put things you like into
  ~/.valgrindrc instead.

Version 0.3.5 (released 2006-06-27)
- Fix asn1_octet_der to handle writes of zero-length buffers, before
  it did not write the ASN.1 length for a zero-length buffer.  This caused
  ASN.1 encodings to be incorrect on 64-bit platforms.
- Add self test that attempt to trigger the above bug.
- Fix test of -Wno-pointer-sign.
- Improve cross-compilation to MinGW by using AC_LIBTOOL_WIN32_DLL.

Version 0.3.4 (released 2006-05-10)
- Really fix encodings.
- Add new self test, tests/Test_encoding.c.
- Self tests are ran under valgrind, if it is available.
- We test for the -Wno-pointer-sign parameter before using it.

Version 0.3.3 (released 2006-05-07)
- Add some 'const' to prototypes.
- Remove some 'unsigned' keywords.
- Corrected asn1_der_coding() bug introduced when it became reentrant.
  Now it produces correct encodings.

Version 0.3.2
- Corrected bug in asn1_der_coding() which overwrited some
  data in the original structure.
- The asn1Parser, asn1Coding and asn1Decoding programs are now installed.

Version 0.3.1
- Support constant size bit strings, as in 'BIT STRING (SIZE(42))'.
  Reported by Cyril Holweck <cyril.holweck@q-free.com>.
- Add two more APIs required by GnuTLS.
- New public APIs:
  asn1_find_node function
  asn1_copy_node

Version 0.3.0
- Export DER utility functions, mostly so that GnuTLS can avoid using
  libtasn1 internals.
- The _asn1* symbols are not exported in the shared library file (when
  using GNU ld).
- The library can now be built using Visual Studio, and the project
  files are included in windows/.
- New public APIs:
  asn1_get_tag_der
  asn1_octet_der
  asn1_get_octet_der
  asn1_bit_der
  asn1_get_bit_der
  asn1_get_length_der
  asn1_length_der
