0.3.2 (October 12, 2016)

• WebVR 1.1 API support (#1931)

0.3.1 (August 25, 2016)

• Fixed requiring A-Frame with Browserify from npm. (#1824)

0.3.0 (August 17, 2016)

0.3.0 improves performance, adds support for the WebVR 1.0 API, and adds tracked controllers (using experimental Gamepad APIs).

Major Changes

• WebVR 1.0 API support. (#1423)
• Default camera is now positioned at 0, 1.6, 0 rather than 0, 1.8, -4. In VR mode, the 1.6m height offset as defined by camera.userHeight is removed. (#1474, #1718)
• Components no longer serialize stringified data to the DOM for performance. Introduced debug mode and flush-to-DOM methods. (#1323)
• No longer able to provide own <canvas> element. (#1474)
• Geometries default to be BufferGeometrys, saving memory at the cost of being more difficult to manually manipulate. Use geometry="buffer: false" to disable. (#633) -- Geometry data is preserved in geometry.metadata. (#1557).
• Removed deprecated declarative events, loader component, and <a-cube>. (29446e0)
• Abstract raycasting-related properties out of the cursor component into the raycaster component. (#1196)
• Have shaders handle applying texture objects to material objects rather than material system. (2cee9eb)
• Removed geometry component's translate property, added a pivot component in extras/. (#1339)
• Renamed defaultAttributes to defaultComponents in registerPrimitive API. (#1460)
• Default lighting setup tweaked. (#1478)

• Added A-Frame Code of Conduct. (#954)
• Reduced webvr-polyfill BUFFER_SCALE to 1 / window.devicePixelRatio only for iOS versions under 10 as a workaround to a Webkit bug. This will cause decrease resolutions on iPhone VR mode temporarily. It can be overridden in window.WebVRConfig.BUFFER_SCALE, but will cause canvas sizing issues upon entering stereo causing people to have to rotate their phones back and forth. (#1803)

Deprecations

• Declarative Events deprecated in favor of ngokevin/aframe-event-set-component. (#1634)
• look-at component deprecated and moved to ngokevin/aframe-look-at-component. (#1447)
• <a-model> primitive deprecated in favor of <a-collada-model> and <a-obj-model>. (#1525)

0.2.0 (March 25, 2016)

0.2.0 improves extensibility:

• Component API has been greatly enhanced with more lifecycle methods, schema options, and property types.
• Components can be applied to primitives (e.g., <a-box>).
• Custom GLSL shaders can be shared and registered to provide more visual effects.

Major Changes

• aframe-core merged with aframe. window.AFRAME exposes what aframe-core was exposing previously (e.g., AFRAME.registerComponent vs. AFRAME.aframeCore.registerComponent). (#368)
• <a-assets> must be declared within <a-scene>. (#910)
• <a-entity>.object3D is now a THREE.Group. Use <a-entity>.setObject3D API to add new 3D objects from components. (#847)
• Bumped three.js to r74 stable. (#1006)
• npm points to a prebuilt bundle of dist/aframe.js.
• Scene <canvas> elements are now appended to the scene by default rather than to the document body. The scene can specify which <canvas> to render to. (c0aa360)
• Primitives such as <a-sphere> directly extend <a-entity> rather than template them. They can be registered with AFRAME.registerPrimitive. (#883)
• <a-template> and HTML Imports logic have been removed. Use https://github.com/ngokevin/aframe-template-component in the meantime. (#883)
• <a-camera> no longer creates a cursor on its own. Do <a-camera><a-cursor></a-cursor></a-camera> instead. (#883)
• Default geometry depth, height, width property values changed from 2 to 1. (#1245)
• Default color of primitive elements such as <a-box> changed to #FFF to not interfere with textures. (#1245)

Deprecations

• loader component deprecated in favor of collada-model and obj-model. (#913)
• <a-model> deprecated in favor of <a-collada-model> and <a-obj-model>. (#883)
• <a-EVENTNAME> elements such as <a-mouseenter> deprecated in favor of <a-event name="EVENTNAME"> (unstable). (#883)
• <a-cube> deprecated in favor of <a-box>. (#883)

Enhancements

• Introduced shaders to extend the material component and to register custom GLSL shaders. (#861)
• Component property types. Property types define how a component property is parsed and stringified. Custom property types can be registered or defined inline with the property in the schema. Built-in property types include array, boolean, color, int, number, selector, selectorAll, string, vec2, vec3, vec4. (d35e56e)
• Single-property components. A component can define itself as consisting of only one property by specifying a type and/or a default value in the schema. (d35e56e)
• Asset management system that blocks scene render.
• Play/pause methods on entities and play/pause handlers on components. (9238861)
• Tick method on components to register a function called on each scene tick. (#823)
• Support for loading .OBJ and .MTL assets. (#788)
• Texture caching for better performance when reusing textures. (#1116)
• Components can be attached to primitives (e.g., <a-sphere>). (#883)
• Introduce systems API (unstable) to provide global scope and services for components. They can be registered wtih AFRAME.registerSystem. (#924)
• Entities, including the scene, wait for their children to load before emitting the loaded event. (a8a4f06)
• Entities emit child-attach when children are attached.
• Most <a-scene> logic moved to configurable components and systems. (#776)
• Support for multiple cameras in a scene and switching between them. (#745)
• Added more events for scene VR mode, material component, model components, and sound component.
• Default geometry segments* property values increased for smoother meshes. (#1245)
• Added more meta tags for mobile web-app capabilities, automatically set properties to video elements for inline video playback on iOS. (#316)
• Added three.js stats to the stats component. (#1223)
• Added <a-torus> primitive. (#1184)

Fixes

• Stop <a-animation> when detached. (#727)
• Fixed <a-animation> begin attribute. (#885)
• Keyboard shortcuts no longer trigger when used alongside modifier keys. (#1211)
• Fixed viewport issues in Twitter webview on IOS. (#1174)
• Raycaster and cursor components can now intersect with loaded models. (#1166)
