+Version 4.2.0 introduced *Scheduled Dispatch* into the library:
+```swift
+temperatureEvent.scheduleQueue(at: DispatchTime.now() + TimeInterval().advanced(by: 4), priority: .highest)

+*Scheduled Event Dispatch* is a massive advantage when your use-case requires a fixed or calculated time delay between the composition of an *Event*, and its *Dispatch* for processing.

 ### Defining an `EventThread`
 So, we have an *Event* type, and we are able to *Dispatch* it through a *Queue* or a *Stack*, with whatever *Priority* we desire. Now we need to define an `EventThread` to listen for and process our `TemperatureEvent`s.

 ## Features Coming Soon
 `EventDrivenSwift` is an evolving and ever-improving Library, so here are lists of the features you can expect in future releases.
 
-Version 4.2.0 (or 5.0.0 if interface-breaking changes are required):
+Version 4.3.0 (or 5.0.0 if interface-breaking changes are required):
 - **Event Pool Scalers** - Dynamic Scaling for `EventPool` instances will be fully-implemented
 - **Latest-Only Events** - A Dispatch option to replace any unprocessed (older) *Events* with the newest *Event* of that specific *Eventable* type. This will be useful for things like sensor readings, where you only care about the most recent value possible (because older values are no longer relevant)
 
-Version 5.1.0 (or 6.0.0 if interface-breaking changes are required):
-- **Event Scheduling** - A Dispatch Scheduler to ensure that *Events* aren't Dispatched until a specific time (or after a specific interval)
