## Features targeted for 22.3.0.0-alpha.0
* `[PlutoRuntime,PlutoCore]` **Initial implementation of the layer system (formerly known as "stage")**
* A "layer", in this context, is a set of assets bound together
by programming logic.
Layer switching and asset management are handled by the engine.
* Layers can be stacked on top of each other and run sequentially
from bottom to top
* Upon layer switch
1. Unload unused assets
2. Load new assets
* Provide multiple means of layer switching
* Two modes with the initial release, asynchronous switching will come at a later date
1. Instant switch
* Assets will be loaded and unloaded synchronously
* The layer switch will happen in one frame
2. Deferred switch
* The layer will continue running until all assets load
* Assets will load synchronously, but at a slower pace
to avoid frame stutter
* Automated asset loading
* All asset management will eventually be handled by `PlutoCore`
* This includes audio clips, textures, sprites
* Add a common interface for all assets
* Let the stage system handle audio playback
* This API should be as neutral as possible and avoid steering towards
game-only use
* The stage manager should be relatively low-overhead and allow multiple
instances
* Allow stages to be inherited from, creating a stack-like structure
* `[PlutoAudio]` Integrate the Audio API with the Stage API
## Features targeted for an unspecified future release
* `[PlutoSpritesheet]` Expanded capabilities
* Support for 9-slice rendering
* Support for animated sprite rendering
* Support for multidirectional sprite rendering
* A spritesheet skeleton editor
* `[PlutoRuntime]`
* Asynchronous switch
* Assets will be loaded in asynchronously, where applicable
* Falls back to deferred switching for synchronous loading,
such as OpenGL texture upload
* `[PlutoGUI]` A fully-fledged GUI engine
* Improve font-rendering capabilities
* Subpixel rendering support [?]
* Reimplement support for bitmap fonts
* Improve upon the support of thread-local Pluto instances
* The long term goal is to allow an unlimited amount of Pluto applications at any given time

### Very high priority
[ *Implemented in the current release.* ]
* Implement the layer system and integrate all existing systems with it
* Improve image loading capabilities, possibly rewrite PlutoLib#TPL
### High priority
[ *Implemented in the next release.* ]
* Finish PlutoAudio
* Depends on the stage system
* Expand upon the Color API

## 22.2.0.0-alpha.2
* `[SDK]` The libraries now always reference natives for all architectures
* `[SDK]` Replaced `NEXT_RELEASE_DRAFT.md` with [an issue tracker](https://github.com/493msi/plutoengine/issues)
* `[PlutoAudio]` **Partial rewrite and support for managed sound effects**
* `plutoengine-demos/` **Added the `jsr-clone` demo**
* `[PlutoSpritesheet]` Renamed `TemporalSprite#getSideCount` to `getFrameCount`
