Implemented more methods from 2.x.
Better compatibility for the classes exposed by js-data.
Switched from Webpack to Rollup for a 7% smaller build (automatic tree-shaking) and built code that's simpler and easier to read.

Changelog

js-data now requires full ES5 support from the runtime. The developer can add es5-shim for older browsers.
DS is now just a container for Model classes. It no longer stores data or metadata.
Settings are no longer inherited via the prototype. A base Model can be created which the remaining Models can extend.
A Model is essentially a constructor function, which can be used to create instance of the Model. A Model has static methods like find and create. The prototype of a Model defines behavior for instances of the Model. Models can be defined using ES6 class syntax. A Model must be "initialized" in order to be able to store data. A Model is automatically initialized if a schema is defined for the Model, or if the Model is created using the .extend method, or the legacy DS#defineResource or DS#defineModel methods.
Use of Object.observe and the observe-js polyfill have been dropped in 3.0.0-alpha.1 (see https://esdiscuss.org/topic/an-update-on-object-observe), replaced with Backbone-style change detection (but unlike with Backbone, you can still treat instances like POJOs!) Change detection is now more “opt in”, so you can use it more wisely when you actually need, improving performance overall.
In 3.0.0-alpha.1 Models (Resources) can now be defined with plain ES6 classes

As this is an alpha build of a complete rewrite from scratch, there is still a lot of work to be done. Some features from 2.x may not have been implemented yet and there are probably bugs. If you're willing to experiment with 3.x, your feedback is appreciated.
3.0.0-alpha.1 gzipped is approximately 40% smaller than 2.8.2 gzipped.
In 3.0.0-alpha.1, the internal store (cache) of each Model (Resource) supports secondary indexes for blazing fast lookups on indexed keys. Where in 2.x a hasMany property accessor performs a O(n) lookup, in 3.0.0-alpha.1 the lookup is performed in O(log n) time.
