This release fixes the infinite loop bug discovered by @kylewetton: https://github.com/jeremyckahn/shifty/issues/117

v2.9.0 incorporates #115 to improve how tweens are rejected.

Specifically, it changes a tween's Promise reject callback signature from:

/**
 * @param {Object} currentState
 * @param {Object} attachment
 */
reject(currentState, attachment)

to

/**
 * @param {Object} data
 * @param {Object} data.currentState
 * @param {Object} data.attachment
 * @param {string} data.error
 */
reject(data)

The toolchain updates in 2.7.0 broke Node compatibility. This release fixes that.

Also:

• Switches the test framework to Jest
• Drops browser test runner (consider using https://www.npmjs.com/package/ndb if you need an interactive debugger)
• Updates all of the devDependencies to their latest versions

Fixes https://github.com/jeremyckahn/shifty/issues/105.

2.5.0 switches to batched tween processing (#87), which significantly improves performance for situations when there are many tweens running at once. You can see a performance comparison between Shifty, GSAP, and jQuery here.

2.5.0 also fixes a minor bug that was introduced in 2.4.0.
