 # News
 
+## v1.4.0 - 2023-08-07
+
+- Implement a `DelayQueue`, i.e. a `QueueStore` with latency between the store and take events.
+- Bugfix to `QueueStore` and `StackStore` for take events on empty stores.
+
 ## v1.3.0 - 2023-08-07
 
 - Implement ordered versions of `Store`, namely `QueueStore` and `StackStore`.

 # Event Latency
 
+There is a built-in [`DelayQueue`](@ref) if you need a store [`Store`](@ref) with latency between `put!` and `take!` events. However here, we show you how you could have built one for yourself. If you modify this in order to construct a particularly useful type of latency store, please contribute it to the library through a pull request.
+
 ## Description 
 In this example we show how to separate the time delay between processes from the processes themselves. We model a communications channel, called a `Cable`, where a sender sends messages regularly each `SEND_PERIOD` time units and a receiver listens each `RECEIVE_PERIOD`. The messages in the cable have a delay fo `DELAY_DURATION` until they reach the recevier.
