## Godot Steering AI Framework 2.1.0 ##

### Features ###

- There is now an `Arrive3d` demo to showcase 3D movement.

### Improvements ###

- All the demos got a bit of attention to improve their feel.

### Changes ###

- `GSAIUtils.vector3_to_angle` now uses the vector's X and Z components to determine angle. Use `GSAIUtils.vector2_to_angle` for 2D use cases.
- `GSAIMatchOrientation` and its subclasses like `GSAIFace` and `GSAILookWhereYouGo` now include a `use_z` property. It should be `true` when using 3D so that facing will be done with the X and Z components.
- The README now mentions a simple way to install the framework.
- Exposed `agent_count` inside the `AvoidCollisionsDemo`.

### Bug fixes ###

- Fixed `GSAIKinematicBody3DAgent` and `GSAIRigidBody3DAgent` trying to use `global_position` instead of `transform.origin`.
- The `SeekFleeDemo`'s boundaries will now match the size of the screen.
- Fixed error when double clicking an item in the DemoPicker.
- Fixed the background sometimes not covering the entire viewport in demos.

## Godot Steering AI Framework 2.0.0 ##

This release brings one new feature and bug fix, and breaking changes to the framework as we renamed all the classes.

**Important**: we renamed all classes from GST\* to GSAI\* (Godot Steering AI). When you upgrade the framework in your project, use the project search and replace feature in Godot (<kbd>Ctrl</kbd> <kbd>Shift</kbd> <kbd>F</kbd>) to find and replace `GST` with `GSAI`.

If you were using `GSTKinematicBodyAgent` or `GSTRigidBodyAgent`, search and replace them respectively with `GSAIKinematicBody3DAgent` and `GSAIRigidBody3DAgent`.

We decided to make this change as soon as possible, as the framework was released a few days ago.

### Features ###

- There is now a main scene with a demo picker, so you can select and play any demo on the fly.
- The demo projects now support resizing and toggling fullscreen with <kbd>F11</kbd>.

### Improvements ###

- We handled all warnings in the framework, so using it won't add warnings to your projects.

### Changes ###

- Renamed all classes from `GST*` (Godot Steering Toolkit) to `GSAI*` (Godot Steering AI).
- Removed `GSTNode2DAgent`, `GSTNodeAgent`, and `GSTSpatialAgent` classes.
    - For specialized steering agents, `GSAIKinematicBody2DAgent`, `GSAIRigidBody2DAgent`, or their 3D equivalent. 
    - If you intend to write your own movement system instead of using Godot's, the base class `GSTSpecializedAgent` is there to help you.
- Renamed `GSAIRigidBodyAgent` and `GSAIRigidBodyAgent` to `GSAIRigidBody3DAgent` and `GSAIRigidBody3DAgent` respectively.
    - 3D nodes like `Sprite`, `KinematicBody`, etc. are being renamed to `Sprite3D`, `KinematicBody3D`, etc. in the upcoming Godot 4.0 release, to be consistent with 2D nodes. We decided to rename them now instead of breaking compatibility in a future release.

### Bug fixes ###

- GSTFollowPath no longer loops back around itself on open paths when `predict_time` is non-zero.

## Godot Steering AI Framework 1.0.0 ##

This is the first major release of the framework. It comes with:

- All the essential steering behaviors: `Arrive`, `AvoidCollisions`, `Blend`, `Cohesion`, `Evade`, `Face`, `Flee`, `FollowPath`, `LookWhereYouGo`, `MatchOrientation`, `Priority`, `Pursue`, `Seek`, `Separation`.
- Group behaviors and detecting neighbors.
- Blending and prioritized behaviors.
- Specialized types to code agents based on physics bodies:
    - For 2D games, `KinematicBody2DAgent` and `RigidBody2DAgent`.
    - For 3D games, `KinematicBody3DAgent` and `RigidBody3DAgent`.
- 9 Godot demos to learn straight from the code.
