+CHANGES
+~~~~~~~
+
+- The update **v0.3.3** has been released with additional features, API changes and fixes.
+
+- MAJOR: Multiobjective Framework: Affine Information Least Squares Algorithm (AILS)
+ - Now you can use AILS to estimate parameters of NARMAX models (and variants) using a multiobjective approach.
+ - AILS can be accessed using `from sysidentpy.multiobjective_parameter_estimation import AILS`
+ - See the docs for a more in depth explanation of how to use AILS.
+ - This feature is related to Issue #101. This work is the result of an undergraduate research conducted by Gabriel Bueno Leandro under the supervision of Samir Milani Martins and Wilson Rocha Lacerda Junior.
+
+- API Change: `regressor_code` variable was renamed as `enconding` to avoid using the same name as the method in `narmax_tool` `regressor_code` method.
+
+- DATASET: Added buck_id.csv and buck_valid.csv dataset to SysIdentPy repository.
+
+- DOC: Add a Multiobjetive Parameter Optimization Notebook showing how to use the new AILS method
+
+- DOC: Minor additions and grammar fixes.
