0.4

July, 2020
========

* New examples
* Support to python 3.8
* New README
* New documentation style
* New complexity meta-features

* Some bug fix

0.3.0

May, 2020
========

* Metafeature extraction with confidence intervals

* Pydoc fixes and package documentation/code consistency improvements

* Reformatted 'model-based' group metafeature extraction methods arguments to
a consistent format (all model-based metafeatures now receive a single
mandatory argument 'dt_model', and all other arguments are optional
arguments from precomputations.) Now it is much easier to use those
methods directly without the main class (mfe) filter, if desired.

* Now accepting user custom arguments in precomputation methods.

* Added 'extract_from_model' MFE method, making easy to extract model-based
metafeatures from a pre-fitted model without using the training data.

* Memory issues

* Now handling memory errors in precomputations, postcomputations and
metafeature extraction as a regular exception.

* Categorical attributes one-hot encoding option

* Added option to encode categorical attributes using one-hot encoding
instead of the current gray encoding.

* New nan-resilient summary functions

* All summary functions now can be calculated ignoring 'nan' values, using
its nan-resilient version.

* Online documentation improvement

0.2.0
