Bjorn Reese and/or Daniel Stenberg.


Bogofilter-local change - 2005-12-30
------------------------------------
* Matthias Andree
  Fix triodef.h to work on systems were empty macros don't default to 0
  in numeric evaluations, such as Sun Workshop 6.


Version 1.11 - 2005/12/26
-------------------------
* Fixed accuracy for denormalized numbers (bug item #758327).

* Glen Davidson
  Fixed scanning of floating-point numbers without a decimal-point (bug item
  #1370427).

* David Byron
  Fixed more compiler warnings.

* Fixed compilation of trio_to_long_double and TRIO_FEATURE_FLOAT (reported by
  David Byron).

* Fixed precision of large floating-point numbers (bug item #1314524).

* Karl Bochert
  Fixed trio_fpclassify_and_signbit to only restore the floating-point
  precision.

* Fixed detection of need for ieee option on FreeBSD/Alpha.

* Added TRIO_SNPRINTF_ONLY compilation.

* Fixed trio_to_double by not using strtod() on Tru64/DECC because it does not
  support hex-floats.

* Fixed crash on 64 bits machines related to a previous workaround in version
  1.9 for uninitialized va_list (reported by Nicolai Tufar, suggestion by
  Douglas Gwyn).

* Patrick Jessee
  Fixed width calculation for %g.

* Added macros for internal features.

* Jon Foster
  Added macros for conditional compilation of many features. Documented all
  the features.

* Karl Bochert
  Fixed problem with Borland C++, which changes the floating-point precision
  for certain math functions (log10() and _fpclass()).

* Karl Bochert
  Fixed compilation warnings on Borland C++.

* Removed any occurrence of #elif because Borland C++ reports wrong line
  numbers when they are present (reported by Karl Bochert).

* David Byron
  Added trio_asprintfv.

* Brian Chapman
  Fixed Mac OS X compilation.

* David Byron
  Fixed several compiler warnings.

* Fixed printing of out-of-range arguments for %hhd and %hd. These arguments
  can be out of range because of default integer promotion.

* Bob Friesenhahn
  Fixed installation of header files.

* Joe Orton
  Added SHELL to Makefile.in to avoid problems with CShells.

* Shaun Tancheff
  Fixed regresion tests for MSVC.

* Craig Berry

-------------------------

  Albert Chin-A-Young).

* Added support for SunOS 4.1.x lack of strerror, tolower, and toupper
  (reported by Peter McCluskey).

* Fixed pedantic compilation with TRIO_MINIMAL.

* Jose Kahan

  Fixed TRIO_VA_START for VMS.

* Rune Enggaard Lausen
  Fixed compilation for Borland C++ Builder.

* Fixed plus sign only to be added for signed numbers.

* Fixed printing of integers with value and precision of zero (reported by
  James Antill).

  Antill).

* Rewrote check for IEEE compilation option to remove dependency on additional
  scripts.

* Mehdi Lavasani
  Makefile install target fixed to work with older install programs.

* Collapsed the DECC, MSVC, HP-UX, and AIX code for trio_fpclassify_and_sign()
  with further preprocessing.

* Craig Berry
  Fixed compilation on VMS.

* Albert Chin-A-Young
  Fixed incorrect conditional expression in trio_isinf.

* Fixed the warnings about uninitialized va_list in the printfv and scanfv
  family without the use of compiler specific pragmas (suggested by Ian
  Pilcher).

* Fixed space flag for floating-point numbers (reported by Ian Main).


Version 1.8 - 2002/07/10
------------------------
* Fixed infinite loop in multibyte handling (reported by Gisli Ottarsson).

* Added the customizable cprintf/cscanf family which enables to user to specify
  input and output stream functions (suggested by Florian Schulze).

* Fixed trio_isinf by removing the HP-UX workaround, and instead making sure
  that the C99 macro will adhere to the trio return values (reported by Luke
  Dunstan).

* Alexander Lukyanov
  Fixed boundary case for scanning and EOF.

* Jacob Navia
  Enabled the L modifier for formatting.

* Added TRIO_MINIMAL to build trio without the string functions.

* Added the R modifier to print rounded floating-point numbers.

* Added trio_to_long_double and long double scanning (the L modifier).

* Added trio_locale_decimal_point, trio_locale_thousand_separator,
  trio_locale_grouping to overwrite locale settings.

* Rewrote TrioWriteDouble to avoid temporary buffers and thus the danger of
  buffer overflows (for instance %.5000f).

* Improved floating-point formatting accuracy.

* Fixed formatting of non-decimal exponents.

* Fixed thousand separator checking.

* Fixed %f scanning to get a float and %lf to get a double.

* Fixed WIN32 compilation (reported by Emmanuel Mogenet)

* Fixed regression test cases to exclude disabled features.


Version 1.7 - 2002/05/07

* Added trio_isfinite, trio_signbit, and trio_fpclassify.

* Added new test cases.


Version 1.6 - 2002/01/13
------------------------
* Added dynamic string functions.

* Rewrote and extended documentation in JavaDoc (using Doxygen).

* Moved and renamed strio functions to triostr.

* Robert Collins
  Added definition for Cygwin.

* Markus Henke
  Added long double workaround for the HP C/iX compiler.

* Marc Verwerft
  Improved error handling for dynamically allocated strings.

* John Fotheringham
  Made trionan compile on OpenVMS.

* Added 'd' and 'D' as exponent letters when using TRIO_MICROSOFT.

* Fixed uninitial memory read for the parameter modifiers.


Version 1.5 - 2001/09/08
------------------------
* Merged with libxml changes.

* Moved NaN and Inf handling to separate file to enable reuse in other
  projects.

* Igor Zlatkovic
  Fixed TrioGenerateNan for MSVC.

* Fixed lots of preprocessor macros and internal data structure names.


Version 1.4 - 2001/06/03
------------------------
* Added hex-float (%a and %A) for scanning.

* Added wide character arguments (%ls, %ws, %S, %lc, %wc, and %C) for both
  printf and scanf.

* Added mutex callbacks for user-specified specifiers to enable applications to
  add thread-safety. These are registered with trio_register, where the
  namespace is set to either ":enter" to lock a mutex, or ":leave" to unlock a
  mutex.

* Added equivalence class expressions for scanning. For example, %[[=a=]] scans
  for all letters in the same equivalence class as the letter 'a' as defined
  by the locale.

* Changed character class expressions for scanning. The expressions must now
  be embedded withing an extra set of brackets, e.g. %[[:alpha:]]. This was
  done to adhere to the syntax of UNIX98 regular expressions.

* Added the possibility to specify standard support (TRIO_C99 etc.) as compiler
  options.

* Fixed conversion of hex-float in StrToDouble.

* Fixed formatting of hex-float numbers.

* Stan Boehm
  Fixed crash on QNX, which happend because some buffers on the stack were too
  big.

* Fixed default precision for %f and %g (reported by Jose Ortiz)

* Howard Kapustein
  Added the I8, I16, I32, and I64 modifiers.

* Jose Ortiz
  Fixed rounding problem for %e.

* Jose Ortiz
  Fixed various problems with the xlC and Sun C++ compilers.


Version 1.3 - 2001/05/16
------------------------
* trio's treatment of the field width when the %e code was used was not
  correct (reported by Gisli Ottarsson). It turns out the fraction part should
  be zero-padded by default and the exponent part should be zero-prefixed if
  it is only one digit. At least that's how the GNU and Sun libc's work. The
  trio floating point output looks identical to them now.
