## [4.3.0]
### Added
- A way to set bottom navigation button colors programmatically via:
 `StepperLayout#setNextButtonColor(int)`/`StepperLayout#setNextButtonColor(ColorStateList)`,
 `StepperLayout#setCompleteButtonColor(int)`/`StepperLayout#setCompleteButtonColor(ColorStateList)` and
 `StepperLayout#setBackButtonColor(int)`/`StepperLayout#setBackButtonColor(ColorStateList)` (issue #132).

### Fixed
- Tab circle background color so that it is possible now to use colors with transparency (issue #207).

## [4.2.0]
### Added
- A new artifact `espresso-material-stepper` with useful Espresso actions and matchers for testing `StepperLayout` with Espresso.

### Fixed

- New stepper type `none` which shows no progress indicator for the steps (issue #154)

- An option to specify the background drawable for `content_overlay` stepper feedback type via `ms_stepperFeedback_contentOverlayBackground`.
- An option to specify the fade out alpha for `content_fade` stepper feedback type via `ms_stepperFeedback_contentFadeAlpha` attribute.

### Changed
- **Breaking change:** Updated Android Support Library version to `25.4.0` to support vector animations without a pre-Lollipop fallback (issue #154)
- **Breaking change:** Changed `setNextButtonLabel` methods in `StepViewModel.Builder` to `setEndButtonLabel` so that it works for both Next and Complete buttons (issue #107)
- **Breaking change:** Split `content` stepper feedback type into `content_progress` and `content_fade`.
