===================
This version removes support for Python version <= 2.7. Now only Python > 3 is supported.

Added
-----
- Adds Ubuntu 18.04 release target.

Changed
-------
- Removes Python version <= 2.7 support.

Other
-----
- Removed the gaussian/mean/median filters from the package. If this is needed in the future it would be better to support it as list-processing kernels instead of 3d volume filters.

===================

Added
-----
- Adds the PDF, CDF and PPF (Quantile function) of the Normal and Gamma distribution as reusable CL functions.

===================

Added
-----
- Adds gamma pdf CL function.

Changed
-------
- Improved the runtime efficiency of the ProcedureRunner by allowing a workgroup size of None.
- Renamed get_nmr_inst_per_problem to get_nmr_observations.
- Updated to the function evaluate signature to use the cl_runtime_info object.

Other
-----
- Refactored the optimization routines to use the RunProcedure paradigm.
- Made the compile flags a list instead of a dict.

===================

Added
-----
- Adds some modeling examples.

===================

Added
-----
- Adds random scan to the Random Walk Metropolis algorithms.

Other
-----
- Renamed 'get_nmr_estimable_parameters' to 'get_nmr_parameters'
- Moved the model building modules to MDT.
- Removed the eval function from the model interface.

=================
This release provides a cleaner interface to the optimization and sampling routines.
Furthermore, it improved the decoupling between the models and the MCMC samplers allowing to, in the future, add
more MCMC samplers.

Added
-----
- Adds additional patience parameter for the line search in the Powell algorithm.

Changed
-------
- Completely restructured the MCMC sampling routines by decoupling the proposal distributions from the model functions.
- Removed some weight models from the model builder and moved those to MDT.
- Removed the 'get_initial_data' method from the model interface.

Other
-----
- Renamed dependency_list to dependencies in the models and library functions.
- Renamed parameter_list to parameters in the model functions.
- Small caching and object initialization updates.
