# Changelog


## v0.2.0 (2022-08-13)


### Enhancements


* Add support for optional inputs
* Add support for non-finite float metrics
* Add support for containers as inputs
* Allow custom activation functions in `Axon.activation`
* Add utilities for debugging model execution
* Add graph manipulation API
* Add lazy model compilation in the form of `Axon.build` and `Axon.compile`. Lazy model compilation removes eager shape calculations in favor of forcing initialization functions to accept an input template. This allows the creation of more complex models without needing to know complex shape logic
* Add `top_k_categorical_accuracy` metric
* Update default model inspection
* Add `Axon.Display.as_table/2`
* Add support for stateful learning rate in optimizers
* Add `Axon.Loop.reduce_lr_on_plateau` event handler
* Update RNN output format to mirror Elixir's convention

### Bug Fixes


* Fix bug in `Axon.resize` methods. Methods other than nearest produced invalid results
* Fix bug with `feature_group_size` in `Axon.conv`. `Axon.conv` parameters did not appropriately initialize according to specified `feature_group_size`
* Fix bug in layer name serialization. `Axon.serialize` did not appropriately freeze names when serializing, which results in deserialization failures when the model is deserialized outside the same process that serialized it

### Deprecations


* Deprecate `Axon.input/3`
* Deprecate `Axon.init/4`
* Deprecate `Axon.Recurrent`
