Changes and Additions to CppAD During 2007
##########################################

mm-dd
*****

12-29
=====
License conversions missed the copyright message at the top
in the following special cases:
``makefile.am`` , ``makefile.in`` , and
``omh/appendix/license.omh`` .

12-25
=====
The :ref:`install-name` instructions have been improved.

12-21
=====
The --with_Documentation
option on the ``configure`` command line caused an error on some
systems because it attempted to copy to many files.
This has been fixed by copying the directory instead of the individual files.

12-08
=====
By mistake, the documentation :ref:`License-name` statement
for the GPL distribution was the same as for the CPL distribution.
This has been fixed.

12-05
=====
Change the name of the spec file from
``cppad-`` *yyyymmdd* . ``spec`` to ``cppad.spec`` .

12-04
=====
Add the capability for the RPM spec file to use a different
prefix directory.

12-03
=====
This is the first version with the rpm spec file
``cppad.spec`` .

12-02
=====
Add the ``DESTDIR`` = *directory* option on the
:ref:`configure@make install` command line.

11-29
=====
The :ref:`unary_standard_math-name` function ``sqrt`` did not link properly
when *Base* was ``AD<double>`` .
This has been fixed.

11-23
=====
The routines ``nan`` and ``isnan`` were failing
for some systems because they use ``nan`` and or ``isnan``
as preprocessor symbols.
This has been fixed; see :ref:`nan@Include@Macros` .
In addition, the example and test :ref:`nan.cpp-name` has been added.

11-18
=====
Speed tests for ``tape_values`` branch were not better than trunk,
so the good parts of that branch (but not all) were merged into the trunk.

The interface specifications for
:ref:`base type requirements<base_require-name>` have been changed so that
CppAD would compile with ``gcc 4.1.1``
(which requires more definitions before use in template functions).
This changed of requirements is demonstrated by the
:ref:`base_complex.hpp-name` and :ref:`base_adolc.hpp-name` examples.

The problem with newer C++ compilers requiring more definitions before use
also required the user to know about ``float`` and ``double``
definitions for the standard math
functions in the CppAD namespace;
see :ref:`base_std_math-name` .

The ``example/test_one.sh`` and ``test_more/test_one.sh``
scripts were modified so that one only need specify the test file name
(does not also need the test routine name). Some of the test routine
declarations were changed from *name* () to
*name* ( ``void`` ) to make this possible.

The program ``test_more/test_more`` was changed to always
report the memory leak test results (same as ``example/example`` ).

The :ref:`PrintFor-name` function was putting an unused variable in the tape.
This has been fixed.

11-06
=====
Added the ``-DRAD_EQ_ALIAS`` compiler flag to the
:ref:`Sacado speed tests<speed_sacado-name>` .
In addition, compiler flag documentation was included for
Sacado and all the other speed tests.

11-05
=====
MS project files have been added for running the
:ref:`cppad<speed_cppad-name>` and
:ref:`double<speed_double-name>`
speed tests.

11-04
=====
The ``cppad/config.h`` file was not compatible with the
Windows install procedure and
the Windows project's could not find a certain include file.
This has been fixed.

The :ref:`unix install<configure-name>` procedure has been modified
so that the one configure flag
``--with-Speed``
builds all the possible executables related to the speed testing.

11-03
=====
Improve the :ref:`speed_main-name` documentation and output
(as well as the title for other sections under :ref:`speed-name` ).

The subversion copy of the :ref:`configure@Configure` script
was not executable.
This has been fixed.

11-02
=====
The instructions for downloading the current version using
``subversion`` have changed.
The user should now directly edit the file
::

   trunk/configure

in order to set the correct date for the installation
and to build the corresponding documentation.

The :ref:`speed-name` section has been slightly reorganized
(the main program and utilities have been separated).

Add :ref:`speed_double-name` for testing the speed of evaluating
functions in ``double`` as apposed to gradients using AD types.

11-01
=====
The instructions for downloading the current version using subversion
have changed.
The user must now execute the command
::

   ./build.sh version

in order to set the correct version number for her (or his) installation.

Add the return status for all the correctness tests
to the documentation; see ``make test`` .

10-30
=====
The download instructions did not update current version number
and this broke the links to the current tarballs.
This has been fixed.

The documentation for :ref:`det_by_minor-name` and :ref:`det_by_lu-name`
has been improved.
The order of the elements in :ref:`det_of_minor-name` has been
corrected (they were transposed but this did not really matter
because determinants of transposes are equal).

The makefiles in the distribution have been changed so that
one can run configure from a directory other than the distribution directory.

10-27
=====
A ``subversion`` method
for downloading CppAD has been added.

The installation was broken on some systems because the
:ref:`configure@Configure` command tried to run
the ``autoconf`` and ``automake`` programs.
This has been fixed by adding
``AM_MAINTAINER_MODE`` to the ``autoconf`` input file.

Extend the
``subversion``
methods to include a full installation and old versions.

10-23
=====
The :ref:`configure@cxx_flags` environment variable
has been changed from ``CPP_ERROR_WARN`` to ``CXX_FLAGS`` .

The command ``configure --help`` now prints a description
of the environment variables
``ADOLC_DIR`` ,
``FADBAD_DIR`` ,
``SACADO_DIR`` ,
``BOOST_DIR`` ,
and
``CXX_FLAGS`` .
In addition, if the environment variables
``POSTFIX_DIR`` or ``CPP_ERROR_WARN`` are used,
an message is printed saying that are not longer valid.

10-22
=====
The correctness checks and speed test wrappers were moved
from the individual package directories to :ref:`speed_main-name` .
This way they do not have to be reproduced for each package.
This makes it easier to add a new package,
but it requires the prototype for
``compute_`` *test_name* to be the same for all packages.

The `Sacado <http://trilinos.sandia.gov/packages/sacado/>`_
package was added to the list of :ref:`speed-name` tests.
In addition, the discussion about how to run each of the
speed tests was corrected to include the *seed* argument.

The *postfix_dir* option
was removed on :ref:`2006-12-05<whats_new_06@mm-dd@12-05>` but
it was not removed from the
:ref:`configure@Configure`
documentation.
This has been fixed.

The routine :ref:`CheckSimpleVector-name` was changed.
It used to require conversion of the form

   *Scalar* ( *i* )

where *i* was ``0`` or ``1`` .
This does not work with when *Scalar* is
``Sacado::Tay::Taylor<double>`` .
This requirement has been changed
(see :ref:`CheckSimpleVector@Restrictions` )
to support of

   *x* = *i*

where *x* has type *Scalar*
and *i* has type ``int`` .

Fix include directives in :ref:`speed_fadbad-name` programs
``det_lu`` , ``det_minor`` , and ``poly`` ,
to use ``FADBAD++`` instead of ``Fadbad++`` directory.

Add ``ADOLC_DIR`` , ``FADBAD_DIR`` , ``SACADO_DIR`` ,
and ``BOOST_DIR``
to the :ref:`configure@Configure` help string.

10-16
=====
Add *seed* argument and
improve :ref:`speed_main-name` documentation.

10-13
=====
Fix the title in :ref:`adolc_det_lu.cpp-name` .
Add the package name to each test case result printed by
:ref:`speed_main-name` .

10-05
=====
Added and example using complex calculations for a
function that is not complex differentiable ``not_complex_ad.cpp`` .
(This example has been removed; see :ref:`complex FAQ<Faq@Complex Types>` .)

10-02
=====
Extend the :ref:`pow-name` function to work for any case where one argument
is ``AD`` < *Base* > and the other is ``double``
(as do the binary operators).

09-06
=====
If the :ref:`method.step<OdeErrControl@Method@step>` function returned
``nan`` (not a number),
it was possible for :ref:`OdeErrControl-name` to drop into an infinite loop.
This has been fixed.

08-09
=====
Let user detect and handel the case where an ODE initial vector *xi*
contains  not a number ``nan``
(see :ref:`Runge45-name` , :ref:`Rosen34-name` , and :ref:`OdeErrControl-name` ).

Use the ``||`` operation instead of ``|``
operator in the ``nan`` function
(The Ginac library seems to use an alias for the type ``bool`` and
does not have ``|`` defined for this alias).

The file ``test_more/ode_err_control.cpp`` was using the
wrong include file name since the change on 08/07.
This has been fixed.

08-07
=====
Sometimes an ODE solver takes to large a step and this results
in invalid values for the variables being integrated.
The ODE solvers :ref:`Runge45-name` and :ref:`Rosen34-name` have been
modified to abort
and return :ref:`nan-name` when it is returned by the differential
equation evaluation.
The solver :ref:`OdeErrControl-name` have been modified to try smaller steps
when this happens.

Fix an :ref:`fun_construct@Sequence Constructor`
referenced to ``Dependent`` in documentation
(was using the :ref:`fun_deprecated-name` one argument syntax).

Add comment about mixing debug and non-debug versions of
CppAD in :ref:`track_new_del@TrackDelVec` error message.

07-30
=====
``CppADCreateBinaryBool`` and ``CppADCreateUnaryBool``
have been replaced by ``CPPAD_BOOL_BINARY`` and
``CPPAD_BOOL_UNARY`` respectively.
In addition, the :ref:`wish_list-name` item for conversion
of all preprocessor macros to upper case been completed and removed.

07-29
=====
The preprocessor macros
``CppADUsageError`` and ``CppADUnknownError``
have been replaced by ``CPPAD_ASSERT_KNOWN`` and
``CPPAD_ASSERT_UNKNOWN`` respectively.
The meaning for these macros
has been included in the :ref:`cppad_assert-name` section.
In addition, the *known* argument to :ref:`ErrorHandler-name`
was wrong for the unknown case.

The :ref:`wish_list-name` item
for conversion of all preprocessor macros to upper case
has been changes (to an item that was previous missing).

07-28
=====
The preprocessor macro ``CPPAD_DISCRETE_FUNCTIOIN`` was defined
as a replacement for ``CppADCreateDiscrete``
which has been deprecated.

07-26
=====
Merge in changes made in ``branches/test_vector`` .

#. 07-26:
   Change all occurrences of ``CppADvector`` ,
   in the files ``test_more/`` * . ``cpp`` and ``speed/`` * /* . ``cpp`` ,
   where changed to ``CPPAD_TEST_VECTOR`` .
   All occurrences of the ``CppADvector`` in the documentation
   were edited to reflect that fact that it has been deprecated.
   The documentation index and search for
   deprecated items has been improved.

#. 07-25:
   Deprecate the preprocessor symbol ``CppADvector``
   and start changing it to
   ``CPPAD_TEST_VECTOR`` .

   Change all occurrences of ``CppADvector`` ,
   in the ``example/`` * . ``cpp`` files,
   to ``CPPAD_TEST_VECTOR`` .

07-23
=====
The :ref:`track_new_del-name` macros
``CppADTrackNewVec`` ,
``CppADTrackDelVec`` , and
``CppADTrackExtend`` have been deprecated.
The new macros names to use are
``CPPAD_TRACK_NEW_VEC`` ,
``CPPAD_TRACK_DEL_VEC`` , and
``CPPAD_TRACK_EXTEND`` respectively.
This item has been removed from the
software guidelines section of the wish list.

The member variable entry in the software guideline
wish list item has be brought up to date.

07-22
=====
Minor improvements to the :ref:`mul_level_adolc_ode.cpp-name` example.

07-21
=====

#. The ``openmp/run.sh`` example programs
   ``example_a11c.cpp`` ,
   ``openmp_newton_example.cpp`` , and
   ``sum_i_inv.cpp``
   have been changed so that they run on more systems
   (are C++ standard compliant).
#. :ref:`base_require-name` :
   The ``IdenticalEqual`` function,
   in the :ref:`base_require-name` specification,
   was changed to ``IdenticalEqualCon``
   (note the :ref:`base_require@API Warning` in the
   *Base* requirement specifications).
#. Implementation of the :ref:`base requirements<base_require-name>` for complex types
   were moved into the :ref:`base_complex.hpp-name` example.

07-20
=====
The download for CppAD was still broken.
It turned out that the copyright message was missing from the file
:ref:`base_adolc.hpp-name` and this stopped the creation of the download files.
This has been fixed.
In addition, the automated testing procedure has been modified so
that missing copyright messages and test program failures will
be more obvious in the test log.

07-19
=====
The download for CppAD has been broken since the example
``mul_level_adolc_ode.cpp`` was added because the
``example/example`` program was failing.
This has been fixed.

07-18
=====
A realistic example using Adolc with CppAD
:ref:`mul_level_adolc_ode.cpp-name` was added.
The documentation for :ref:`track_new_del-name` was improved.

07-14
=====
Add a discussion at the beginning of
:ref:`mul_level_ode.cpp-name` example
(and improve the notation used in the example).

07-13
=====
Separate the include file
:ref:`base_adolc.hpp-name`
from the :ref:`mul_level_adolc.cpp-name` example
so that it can be used by other examples.

06-22
=====
Add :ref:`mul_level_adolc.cpp-name` , an example that demonstrates using
``adouble`` and for the :ref:`Base<base_require-name>` type.

The :ref:`get_started.cpp-name`
example did not build when
the ``--with-Introduction`` and
``BOOST_DIR`` options were included on the
:ref:`configure@Configure` command line.
In fact, some of the :ref:`speed-name` tests also had compilation errors
when ``BOOST_DIR`` was include in the configure command.
This has been fixed.

There was a namespace reference missing in the files
that could have caused compilation errors in the files
``speed/cppad/det_minor.cpp`` and
``speed/cppad/det_lu.cpp`` .
This has been fixed.

06-20
=====
The MS project
``test_more/test_more.vcproj`` would not build because
the file ``test_more/fun_check.cpp`` was missing;
this has been fixed.
In addition,
fix warnings generated by the MS compiler when compiling the
``test_more/test_more.cpp`` file.

Add a section defining the :ref:`Base type requirements<base_require-name>` .
Remove the *Base* type restrictions from the :ref:`Faq-name` .
Make all the prototype for the default Base types agree with
the specifications in the Base type requirements.

Fix the description of the ``tan`` function in
:ref:`unary_standard_math-name` .

06-14
=====
The routine :ref:`Rosen34-name` ( :ref:`Runge45-name` ) had a division
of a ``size_t`` ( ``int`` ) by a *Scalar* ,
where *Scalar* was any :ref:`NumericType-name` .
Such an operation may not be valid for a particular numeric type.
This has been fixed by explicitly converting the
``size_t`` to an ``int`` ,
then converting the ``int`` to a *Scalar* ,
and then preforming the division.
(The conversion of an ``int`` to any numeric type must be valid.)

05-26
=====
If the *Base* type is not ``double`` ,
the :ref:`compound assignment<compound_assign-name>` operators did not
always allow for ``double`` operands. For example,
if *x* had type ``AD< AD<double> >``

   *x*  += .5;

would slice the value ``.5`` to an ``int``
and then convert it to an ``AD< AD<double> >`` .
This has been fixed.

This slicing has also been fixed in the
:ref:`assignment<ad_assign-name>` operation.
In addition, the assignment and copy operations
have been grouped together in the documentation; see :ref:`ad_ctor-name` and :ref:`ad_assign-name` .

05-25
=====
Document usage of ``double`` with
binary arithmetic operators,
and combine all those operators into one section (:ref:`ad_binary-name` ).

The documentation for all the :ref:`compound assignment<compound_assign-name>`
operators has been grouped together.
In addition, a
compound assignment wish list item has been added
(it was completed and removed with the
:ref:`whats_new_07@mm-dd@05-26` update.)

05-24
=====
Suppose that *op* is a binary operation and we have

   *left* *op* *right*

where one of the operands was ``AD< AD<double> >`` and
the other operand was ``double`` .
There was a bug in this case that caused the ``double``
operand to be converted to ``int`` before
being converted to ``AD< AD<double> >`` .
This has been fixed.

05-22
=====
The Microsoft
examples and testing
project file ``example/example.vcproj``
was missing a reference to the
source code file ``example/reverse_two.cpp`` .
This has been fixed.

05-08
=====
Reverse mode does not work with the
:ref:`pow-name` function when the base is less than or equal zero
and the exponent is an integer.
For this reason, the :ref:`pow_int-name` function
is no longer deprecated (and is used by CppAD when the exponent
has type ``int`` ).

05-05
=====
Third and fourth order derivatives were included in the
routine ``test_more/sqrt.cpp`` that tests square roots.

The return value descriptions were improved for the introduction
examples:
:ref:`exp_2_for1<exp_2_for1@Return Value>` ,
:ref:`exp_2_for2<exp_2_for2@Return Value>` ,
:ref:`exp_eps_for1<exp_eps_for1@Return Value>` , and
:ref:`exp_eps_for2<exp_eps_for2@Return Value>` .

The summation index in :ref:`sqrt_reverse-name` was changed from
:math:`k` to :math:`\ell` to make partial differentiation
with respect to :math:`z^{(k)}` easier to understand.
In addition, a sign error was corrected near the end of
:ref:`sqrt_reverse-name` .

The dimension for the notation :math:`X` in
:ref:`reverse_identity-name` was corrected.

The word mega was added to the spelling exception list for
``openmp/run.sh`` .

04-19
=====
Improve connection from :ref:`reverse_identity-name` theorem
to :ref:`reverse_any-name` calculations.

Improve the ``openmp/run.sh`` script.
It now runs all the test cases at once in addition
to including multiple number of thread cases for each test.

Add the ``sum_i_inv_time.cpp`` OpenMP example case.

There was a typo in the
:ref:`forward_order@Second Order` discussion
(found by Kipp Martin).
It has been fixed.

04-17
=====
Add a paragraph to :ref:`reverse_identity-name` explaining
how it relates to :ref:`reverse_any-name` calculations.
Add description of
:ref:`first<reverse_any@First Order>` and
:ref:`reverse_any@Second Order`
results in :ref:`reverse_any-name` .

04-14
=====
Simplify the :ref:`Reverse-name` mode documentation by creating
a separate :ref:`reverse_two-name` section for second order reverse,
making major changes to the description in :ref:`reverse_any-name` ,
and creating a third order example :ref:`rev_checkpoint.cpp-name` for
reverse mode calculations.

Improve the :ref:`reverse_identity-name` proof.

04-11
=====
Merge in changes made in ``branches/intro`` .

#. 04-11:
   Add :ref:`exp_eps_rev2-name` and its verification routine
   :ref:`exp_eps_rev2.cpp-name` .

#. 04-10:
   Finished off :ref:`exp_2_rev2-name` and
   added :ref:`exp_2_rev2.cpp-name` which verifies its calculations.
   Added second order calculations to :ref:`exp_2_cppad-name` .
   Added :ref:`exp_eps_for2-name` and its verification routine.

#. 04-07:
   Added a preliminary version of :ref:`exp_2_rev2-name`
   (does not yet have verification or exercises).

#. 04-06:
   Fixed a problem with the Microsoft Visual Studio project file
   ``introduction/exp_apx/exp_apx.vcproj``
   (it did not track the file name changes of the form
   ``exp_apx/exp_2_for`` to ``exp_apx/exp_2_for1``
   on 04-05).

   Added :ref:`exp_2_for2-name` to introduction.

#. 04-05:
   Use order expansions in introduction; e.g., the
   :ref:`exp_2_for2@Second Order Expansion`
   for the :ref:`exp_2-name` example.

03-31
=====
Merge in changes made in ``branches/intro``
and remove the corresponding Introduction item from the wish list:

#. 03-31:
   Create the a simpler exponential approximation in the :ref:`introduction-name`
   called :ref:`exp_2-name` which has a different program
   variable for each variable in the operation sequence.

   Simplify the :ref:`exp_eps-name` approximation using the
   :math:`v_1 , \ldots , v_7` notation so that variables directly
   correspond to index in operation sequence (as with the :ref:`exp_2-name`
   example).

#. 03-30:
   The Microsoft project file ``introduction/exp_apx/exp_apx.vcproj``
   was referencing ``exp_apx_ad.cpp`` which no longer exists.
   It has been changed to reference ``exp_apx_cppad.cpp``
   which is the new name for that file.

03-29
=====
Fixed entries in this file where the year was mistakenly used for the month.
To be more specific, 07 ``-`` *dd* was changed to 03 ``-`` *dd*
for some of the entries directly below.

Corrected some places where ``CppAD`` was used in stead of ``Adolc``
in the :ref:`adolc_poly.cpp-name` documentation.

Added an Introduction and
:ref:`wish_list@Tracing` entry to the wish list.
(The Introduction item was completed on :ref:`whats_new_07@mm-dd@03-31` .)

03-20
=====
Example A.1.1c, ``example_a11c.cpp`` ,
from the OpenMP 2.5 standards document,
was added to the tests that can be run using ``openmp/run.sh`` .

03-15
=====
Included the changes from openmp branch
so that so CppAD does not use the OpenMP ``threadprivate`` command
(some systems do not support this command).

#. 03-15:
   Add command line arguments to ``openmp_newton_example.cpp`` , and
   modified ``openmp/run.sh`` to allow for more flexible testing.

#. 03-14:
   Fixed some Microsoft compiler warnings by explicitly converting from
   ``size_t`` to ``int`` .

   In the Microsoft compiler case, the ``cppad/config.h`` file had
   the wrong setting of ``GETTIMEOFDAY`` .
   The setting is now overridden (and always false) when the
   ``_MSC_VER`` preprocessor symbol is defined.

   Some minor changes were made in an effort to speed up the multi-threading case.

#. 03-13:
   Started a new openmp branch and created a version of CppAD
   that does not use the OpenMP ``threadprivate`` command
   (not supported on some systems).

03-09
=====
Included the changes from openmp branch
so that OpenMP can be used with CppAD,
see :ref:`omp_max_thread-name` .
The changes below
were made in the openmp branch and transferred to the trunk on 03-09.

#. 03-28:
   The conditional include commands were missing on some include files;
   for example
   ::

      # ifndef CPPAD_BENDER_QUAD_HPP
      # define CPPAD_BENDER_QUAD_HPP

   was missing at the beginning of the :ref:`BenderQuad-name` include file.
   This has been fixed.

   The ``speed_test`` routines :ref:`speed_test@Timing` was
   changed to use ``gettimeofday`` if it is available.
   (``gettimeofday`` measures wall clock time
   which is better in a multi-threading environment).

   Added the user multi-threading interface
   :ref:`omp_max_thread-name` along with its examples
   which are distributed in the directory ``openmp`` .

   The ``speed/`` * . ``hpp`` files have been moved to
   ``include/cppad/speed/`` * . ``hpp`` and the corresponding wish list
   item has been removed.

   The multiple tapes with the same base type wish list item
   have been removed (it's purpose was multi-threading which
   has been implemented).

#. 02-27:
   The :ref:`speed-name` include files are currently being distributed
   above the ``cppad`` include directory.
   A fix this wish list item has been added.

   Multiple active tapes required a lot of multi-threading access
   management for the tapes. This was made simpler (and faster)
   by having at most one tape per thread.

#. 02-22:
   The include command in the :ref:`speed_test-name` documentation was
   ::

      # include <speed/speed_test.hpp>

   but it should have been
   ::

      # include <cppad/speed_test.hpp>

   This has been fixed.

#. 02-17:
   An entry about optimizing the operation
   sequence in an :ref:`ADFun<fun_construct-name>` object was added to the
   :ref:`wish_list-name` .

   Change the argument syntax for :ref:`Dependent-name` and deprecate the
   :ref:`old Dependent syntax<fun_deprecated@Dependent>` .

#. 02-16:
   Added ``VecAD`` < *Base* > as a valid argument type for the
   :ref:`con_dyn_var@Parameter`
   and :ref:`con_dyn_var@Variable` functions.
   In addition, :ref:`VecAD@Base Indexing`
   is was extended to be allowed during taping so long as the
   VecAD object is a parameter.

#. 02-15:
   Fixed the ``example/test_one.sh`` script
   (it was using its old name ``one_test`` ).

02-06
=====
The :ref:`BenderQuad-name` documentation was improved by adding the fact
that the *x* and *y* arguments to the ``f`` . *dy*
member function are equal to the *x* and *y* arguments
to ``BenderQuad`` . Hence values depending on them can be stored
as private objects in *f* and need not be recalculated.

02-04
=====
The method for distributing the documentation needed to be
changed in the top level ``makefile.am`` in order to
be compatible with automake version 1.10.

02-03
=====
The change on :ref:`whats_new_07@mm-dd@02-01` had a new, saved as a static
pointer, with no corresponding delete.
This was not a bug, but it has been changed to avoid
an error message when using CppAD with
`valgrind <http://valgrind.org/>`_.

The change to the ``pow`` function on
:ref:`06-12-10<whats_new_06@mm-dd@12-10>` did not include the
necessary changes to the sparsity calculations.
This has been fixed.

02-02
=====
Fix minor errors and improve
profiling documentation.
Also change the problem sizes used for the :ref:`speed-name` tests.

02-01
=====
There seems to be a bug in the cygwin version of g++ version 3.4.4
with the -O2 flag whereby some static variables in static member functions
sometimes do not get constructed before being used. This has been
avoided by using a static pointer and the new operator in cppad/local/ad.hpp.

01-29
=====
The copyright message was missing from some of the distribution files
for some new files added on :ref:`06-12-15<whats_new_06@mm-dd@12-15>` .
This resulted in the
tarballs * . ``tgz`` and * . ``zip``
not existing for a period of time.
The automated tests have been extended so that this should not happen again.
