* Piecewise linear (PWL) functions are now supported. An API is now available
on ``docplex.mp.model`` to create PWL functions and to create constraints using these PWL functions.
PWL functions may be defined with breakpoints (default API) or by using slopes. Some simple arithmetic is
also available to build new PWL functions by adding, subtracting, or scaling existing PWL functions.
* DOcplex has undergone a significant overhaul effort that has resulted in an average of 30-50% improvement
of modeling run-time performance. All parts of the API benefit from the performance improvements: creation of variables and constraints, removal of constraints, computation of sums of variables, and so on.
* Constraints are now fully editable:
the expressions of a constraint can be modified.
Similarly, the objective expression can also be modified. This allows for complex workflows in which the model is modified after a solve and then solved again.
* docplex is now available on Anaconda cloud and can be installed via the conda installation packager.
See the `IBM Anaconda home <https://anaconda.org/IBMDecisionOptimization>`_
CPLEX Community Edition for Python is also provided on Anaconda Cloud to get free local solving capabilities with limitations.
* Support of ``~/.docplexrc`` configuration files for ``docplex.mp.context.Context`` is now dropped.
This feature has been deprecated since 1.0.0.
* Known incompatibility: class ``docplex.mp.model.AbstractModel`` moved to ``docplex.mp.absmodel.AbstractModel``.
Samples using this class have been updated.
