Key.justReleased has bee renamed to Key.upDuration which is a much clearer name for what the method actually does. See Key.justUp for a nice clean alternative.
Key.justDown allows you to test if a Key has just been pressed down or not. You can only call justDown once per key press. It will only return `true` once, until the Key is released and pressed down again. This allows you to use it in situations where you want to check if this key is down without using a Signal, such as in a core game loop (thanks @pjbaron #1321)

We have separated the logic and render updates to permit slow motion and time slicing effects. We've fixed time calling to fix physics problems caused by variable time updates (i.e. collisions sometimes missing, objects tunneling, etc)
Once per frame calling for rendering and tweening to keep things as smooth as possible
Calculates a `suggestedFps` value (in multiples of 5 fps) based on a 2 second average of actual elapsed time values in the `Time.update` method. This is recalculated every 2 seconds so it could be used on a level-by-level basis if a game varies dramatically. I.e. if the fps rate consistently drops, you can adjust your game effects accordingly.
Game loop now tries to "catch up" frames if it is falling behind by iterating the logic update. This will help if the logic is occasionally causing things to run too slow, or if the renderer occasionally pushes the combined frame time over the FPS time. It's not a band-aid for a game that floods a low powered device however, so you still need to code accordingly. But it should help capture issues such as gc spikes or temporarily overloaded CPUs.
It now detects 'spiralling' which happens if a lot of frames are pushed out in succession meaning the CPU can never "catch up". It skips frames instead of trying to catch them up in this case. Note: the time value passed to the logic update functions is always constant regardless of these shenanigans.
Signals to the game program if there is a problem which might be fixed by lowering the desiredFps
Time.desiredFps is the new desired frame rate for your game.
Time.suggestedFps is the suggested frame rate for the game based on system load.
Time.slowMotion allows you to push the game into a slow motion mode. The default value is 1.0. 2.0 would be half speed, and so on.
Time.timeCap is no longer used and now deprecated. All timing is now handled by the fixed time-step code we've introduced.
ScaleManager.calibrate is a private method that calibrates element coordinates for viewport checks.
ScaleManager.aspect gets the viewport aspect ratio (or the aspect ratio of an object or element)
ScaleManager.inViewport tests if the given DOM element is within the viewport, with an optional cushion parameter that allows you to specify a distance.
ScaleManager.scaleSprite takes a Sprite or Image object and scales it to fit the given dimensions. Scaling happens proportionally without distortion to the sprites texture. The letterBox parameter controls if scaling will produce a letter-box effect or zoom the sprite until it fills the given values.
ScaleManager.viewportWidth returns the viewport width in pixels.
ScaleManager.viewportHeight returns the viewport height in pixels.
ScaleManager.documentWidth returns the document width in pixels.
ScaleManager.documentHeight returns the document height in pixels.
* pointerN are aliases to backed pointers[N-1] array. This simplifies (and increases the efficiency of) looping through all the pointers when applicable; also eliminates pointer-existance checks Removes various hard-coded limits (added MAX_POINTERS); changed maxPointers default
* Removed some special-casing from cases where it did not matter
* Removed === false/true, == usage for consistency, changed missing value check to typeof, etc.
* Updated documentation for specificty; added @public\@protected
* @deprecated currentPointers due to odd set pattern; totalCurrentPointers is more appropriate.
(thanks @pnstickne #1283)
Polygon.area is now only calculated when the Polygon points list is modified, rather than on every call.
Phaser.Polygon can now accept the points list in a variety of formats: Arrays of Points, numbers, objects with public x/y properties or any combination of, or as a parameter list (thanks @pnstickne for the original implementation #1267)
Polygon.contains now correctly calculates the result (thanks @pnstickne @BurnedToast #1267)
Particle.Emitter.explode (or `Emitter.start` with the `explode` parameter set to `true`) will immediately emit the required quantity of particles and not delay until the next frame to do so. This means you can re-use a single emitter across multiple places in your game that require explode-style emissions, just by adjusting the `emitter.x` and `emitter.y` properties before calling explode (thanks Insanehero)
Cache.autoResolveURL is a new boolean (default `false`) that automatically builds a cached map of all loaded assets vs. their absolute URLs, for use with Cache.getURL and Cache.checkURL. Note that in 2.1.3 and earlier this was enabled by default, but has since been moved behind this property which needs to be set to `true` *before* you load any assets to enable.
Cache._resolveUrl has been renamed to Cache._resolveURL internally and gained a new parameter. This method is a private internal one.
Cache.getUrl is deprecated. The same method is now available as Cache.getURL.
XML files weren't being added to the URL map.
Cache._resolveURL was causing a Sound double-load in Firefox and causing errors (thanks @domonyiv #1253)
