Release Notes for 2026

=====

#.  Change the cppad 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 documentation uses rst),
    but 4 spaces is the most common choice used by programmers.

#.  Rename the default git branch from master to main.

#.  Use the a system install for ipopt and remove the
    ``bin/get_ipopt.sh`` script. (This was done because ipopt
    is available on most systems.)
