Changes and Additions to CppAD During 2009

Introduction
This section contains a list of the changes to CppAD during 2009 (in reverse order by date). The purpose of this section is to assist you in learning about changes between various versions of CppAD.

01-31
Modify cppad/local/op_code.hpp to avoid incorrect warning by g++ version 4.3.2 when building pycppad (a python interface to CppAD).

01-18
Sometimes an error occurs while taping AD operations. The abort_recording function has been added to make it easier to recover in such cases.

Previously, CppAD speed and comparison tests used Adolc-1.10.2. The version used in the tests has been upgraded to Adolc-2.0.0.

A discussion has been added to the documentation for Jacobian about its use of forward or reverse mode depending on which it estimates is more efficient.

A minor typo has been fixed in the description of W(t, u) in reverse_any . To be specific,  o ( t^{p-1} ) * t^{1-p} \rightarrow 0 has been replaced by  o ( t^{p-1} ) / t^{1-p} \rightarrow 0 .

01-06
