+
+## New Example Programs
+2 new example programs have been added to FastJ: Simple Audio and Behaviors! Check them out below:
+
+- [FastJ Audio](https://example.fastj.dev/audio/Main.java) -- Simple Audio Playing/Loading in FastJ
+- [Behaviors](https://example.fastj.dev/behaviors/Main.java) -- Behaviors in FastJ
+
+
+## Replace Issue Templates with Issue Forms
+All of FastJ's issue templates have been replaced with GitHub's [issue forms](https://docs.github.com/en/communities/using-templates-to-encourage-useful-issues-and-pull-requests/configuring-issue-templates-for-your-repository#creating-issue-forms). [Check them out here](https://github.com/fastjengine/FastJ/issues/new/choose)!
+
+
+## Audio from Java URLs
+Loading/Playing Audio with FastJ can now be done using `java.net.URL`, enabling easy use of sound files contained in a jarfile through the `ClassLoader`.
+
+
+## General Changelog
+
+### Additions
+- Added explicit methods to manage behaviors/keys pressed in `LogicManager`
+- `initBehaviors` -- requests that the `LogicManager` initialize its behaviors
+- `updateBehaviors` -- requests that the `LogicManager` update its behaviors
+- `processKeysDown` -- requests that the `LogicManager` process keys pressed down
+- `BehaviorManager.destroyListenerList` for destroying the behaviors of any `BehaviorHandler`'s behavior listener list
+- `BehaviorHandler.destroyBehaviorListeners` for calling the `BehaviorManager`'s behavior destroying method
+
+
+### Breaking Changes
+- (by [@Sammie156][Sammie156-Link], PR [#72][FastJ-Pull-72]) Renamed `SupportedFileFormats` to [`SupportedModelFormats`](https://github.com/fastjengine/FastJ/blob/main/src/main/java/tech/fastj/graphics/io/SupportedModelFormats.java)
+- `SceneManager` no longer handles input at the update() stage. All input dealt with in `SceneManager` will be called _before_ `render()`
+- `SceneManager` behavior initialization now occurs after background adjustments and scene initialization
+
+
+### Bug Fixes
+- ([#96][FastJ-Issue-96]) Fixed issue where `LogicManager` did not initialize, update, or destroy behaviors
+- Fixed issue where `LogicManager` did not act on keys pressed down
+- ([#99][FastJ-Issue-99]) Added behavior destroy calls to both `SimpleManager` and `Scene` classes' `reset` methods
+
+
+### Other Changes
+- (by [@SaadRehmanCS][SaadRehmanCS-Link], PR [#71][FastJ-Pull-71]) include default case in `AudioEventListener.AudioEventProcessor` switch statements which throws `IllegalStateException`
+- (by [@Sammie156][Sammie156-Link], PR [#80][FastJ-Pull-80]) removed unnecessary casts in `Gradient.java` and `Point.java`
+- (by [@Sammie156][Sammie156-Link], PR [#84][FastJ-Pull-84]) removed more unnecessary casts in `Point.java` and `MemoryAudioPlayer.java`
+- (internal) Replaced `update/init/renderCurrentScene` methods with `safeUpdate/Init/Render` methods, respectively
+- (internal) Reorganize unit tests to match main package structure
+- (internal) Added unit tests to cover loading/playing audio with URLs
+- (internal) Added unit tests to cover unloading multiple audio files at once
