New Functionality
    The Create model UI has been updated to look a bit cleaner.
Bug Fixes
    The dropdown on the components in the workspace now works.

Bugs Fixes
    Fixed progress bar during training; it now reaches 100% every time.

Version 0.12.1 (May 7, 2021)

Note: this version has been removed due a critical error.

Version 0.12.0 (May 5, 2021)

New Functionality
    The old Create Model popup together with the template has been removed. This means that models created pre-0.12 will no longer be usable after upgrading to 0.12.0.
    A new featured called Data Wizard has been introduced. The Data Wizard provides a more structured way to load your data, making the models data centric. It works by:
      allowing you to load a CSV file.
      allowing you to define the CSV file (specifying which columns are the input and target, and their types).
      providing you with a recommended model that can be run immediately.
    There are currently four supported column types in the Data Wizard: Numerical, Categorical, Binary, and Image, allowing you to mix them to build models such as: Image Classification, Regression, Segmentation, simple Image Generation, Autoencoder, etc. Read more about the Data Wizard here. Note that this link will become available once we document this functionality.
    Object Detection has been temporarily removed.
    GAN has been temporarily removed.
    Pre-trained models have been added as components under the Deep Learning, including VGG16, ResNet50, InceptionV3, and MobileNetV2.
    Data components have been removed and replaced by Input and Target components.
    Training components have been removed. The training engine is now running behind the scenes and has been generalized to work for all above mentioned cases.
    The Statistics View has received a slight update, where it now shows statistics based on the Inputs and Targets rather than the Training components.
    The Test View has been reworked. You can now run one (or many) tests on one (or many) of your models. The current tests available are: Confusion Matrix and Metrics Table.
Bug Fixes
    Changing the model path will no longer cause saving checkpoints to crash in Windows.
    Zooming by inputting a number will no longer cause the components placement to change.
    The correct TensorFlow version (2.4.1) is now shown in the bottom right.
