+- Now you can listen to playback events using `stream` (a broadcast stream) inside `AudioPlayer`. This was a great problem in earlier version as one always needs to trigger UI updates whenever playback progresses, ends etc.
+- One of the big problems in earlier version was that there was no way to detect if an audio playback has ended after completion. Resulting in issues like #25 & #26. Now `audio.isCompleted` stores `bool` if an audio has ended, same can be accessed from `stream`.
+- Added a new `Queue` class to play audio files sequentially, without having to deal with things like `audio.isCompleted` etc. manually.
+- Added methods to deal with `Queue` or repeat playback etc.
+- Now you can provide any random `id` while creating new instance of `AudioPlayer`, this was a big problem earlier as new `id` had to be consecutive to earlier one.
+- Now you can access same instance of `AudioPlayer` even if you make new constructor, by providing same `id`. 
+- Now asset files can be played & loaded into `AudioPlayer` using `load` method.
+  - `AudioSource` class has two static methods
+    - `AudioSource.fromFile` to load an audio file.
+    - `AudioSource.fromAsset` to load an audio asset.
+- Now audio field stores `Audio` object, inside the AudioPlayer class & contains following fields to get information about current playback.
+  - `file`: Current loaded `File`.
+  - `isPlaying` : Whether file is playing.
+  - `isCompleted`: Whether file is ended playing.
+    - By default once playback is ended, `stop` method is called & `AudioPlayer` is reverted to initial configuration.
+  - `isStopped`: Whether file is loaded.
+  - `position`: Position of current playback in `Duration`.
+  - `duration`: Duration of current file in `Duration`.
+- Now contructor of `AudioPlayer` no longer calls async methods, which could result in false assertions.
+- Now `ma_resource_manager` is used from `miniaudio_engine` with `MA_DATA_SOURCE_FLAG_STREAM` flag.
+  - This will improve general performance during playback, as whole file will not be loaded into memory.
+- Structure of code improved & separated into various files & classes.
+- Now device handling is present in an entirely separate class `AudioDevices`.
+- Improvements to how methods are identified & called in method channel. `flutter_types.hpp` improves code readability. 
+- Other bugs that randomly caused termination after false assertions are also fixed to an extent.
+- Removed wave & noise APIs temporarily. Apologies to everyone & [MichealReed](https;//github.com/MichealReed).
