Release Notes for 2026
######################

mm-dd
*****

04-14
=====
In ``bin/example_install.sh``,
add ``'metis'`` to the list of system install packages that are required
by cppad_mixed.
This improves the sparse linear algebra solver used by the ipopt (the cppad_mixed optimizer).

04-13
=====
#.  Fix some warnings during :ref:`check_install.sh-name` by treating
    eigen include files like system include files.

#.  Advance to cppad-20260412. This makes the cppad library dynamic,
    instead of static in the Darwin system case; i.e. Mac OS.

#.  Change the C++ compiler standard from -std=c++11 to -std=c++17
    (c++14 or higher is necessary for modern eigen).

04-08
=====
Change the cppad_mixed source code and documentation to use 4 spaces for
one tab; i.e., one level of indentation.
This used to be 3 spaces because that works well with rst lists
(the cppad_mixed documentation uses rst),
but 4 spaces is the most common choice used by programmers.

01-25
=====
#. Change cmake commands so they work when cross compiling.
#. Change minimum required cmake version to 3.10 (to avoid warnings).

01-06
=====
These changes are included in the 2026.0.0 version of cppad_mixed:

#. Advance to cppad-20260000.0.

#. Fix some documentation links to external web that have changed.

#. Use typos to find and fix spelling errors in the source code.
   Most all of theses were id comments that were not part of the documentation.
   One however was a source code configuration error in the spelling of
   CHOLMOD_suffix_try.

#. Change the default branch from master to main.

#. Create the cppad_mixed-2026.0.0 release.
