 * Added a particle system for effects like smoke, fire, sparks, etc. See `ParticleSystem`, `Particle`, `ParticleBurst`, `BoxEmitter`, `CircleEmitter`, `ConeEmitter`, `ParticleEmitter`, and `SphereEmitter`, and the new Sandcastle examples: `Particle System` and `Particle System Fireworks`. [#5212](https://github.com/AnalyticalGraphicsInc/cesium/pull/5212)
 * Added an `options.request` parameter to `loadWithXhr` and a `request` parameter to `loadArrayBuffer`, `loadBlob`, `loadImageViaBlob`, `loadText`, `loadJson`, `loadJsonp`, `loadXML`, `loadImageFromTypedArray`, `loadImage`, `loadCRN`, and `loadKTX`.
 * `CzmlDataSource` and `KmlDataSource` load functions now take an optional `query` object, which will append query parameters to all network requests. [#5419](https://github.com/AnalyticalGraphicsInc/cesium/pull/5419), [#5434](https://github.com/AnalyticalGraphicsInc/cesium/pull/5434)
+* Added `options.clock`, `options.times` and `options.dimensions` to `WebMapTileServiceImageryProvider` in order to handle time dynamic and static values for dimensions.
+* Added `fromIso8601`, `fromIso8601DateArray`, and `fromIso8601DurationArray` to `TimeIntervalCollection` for handling various ways groups of intervals can be specified in ISO8601 format.
+* Added `fromJulianDateArray` to `TimeIntervalCollection` for generating intervals from a list of dates.
 * Added Sandcastle demo for setting time with the Clock API [#5457](https://github.com/AnalyticalGraphicsInc/cesium/pull/5457);
 * Added Sandcastle demo for ArcticDEM data. [#5224](https://github.com/AnalyticalGraphicsInc/cesium/issues/5224)
 * Fixed geocoder bug so geocoder can accurately handle NSEW inputs [#5407](https://github.com/AnalyticalGraphicsInc/cesium/pull/5407)
