Version 6.1

• Fixed the contAwait function.

Version 6.0

• Introduced the discrete event priorities.

Version 5.9

• Added the support of GHC 8.6 and dropped the support of old versions that do not have Monad.Fail.

Version 5.8

• Satisfying a new requirement of the MonadMask class type.

Version 5.7

• Implemented MonadMask and MonadCatch for basic simulation computations.

Version 5.6

• Lars Kuhtz added the support of GHC 8.4.

Version 5.5

• Added the 4th order Runge-Kutta 3/8-method.

• Added experimental functions delayByDT and delayIByDT.

Version 5.4

• A more correct treating of the stop time. Earlier, the final integration time point was used instead of the stop time in some functions.

Version 5.3.1

• Increased the speed of simulation.

Version 5.3

• Introduced the result source titles, which can be useful when plotting the charts.

• Added functions newSignalInTimeGrid and timeGrid.

Version 5.2

• Using the mwc-random package for generating random numbers by default.

Version 5.1

• Includes changes destined for Aivika Exension Pack.

• Minor changes in the resource preemption statistics.

• Added the statistics reset.

Version 5.0

• Added the Composite monad transformer.

• Added the Channel computation.

• Breaking change: modified signatures of functions signalStream and streamSignal.

• Breaking change: the signalProcessor function is replaced with channelProcessor.

• Breaking change: the processorSignaling function is replaced with processorChannel.

• Added module Signal.Random.

• Added functions arrivalTimerSignal and arrivalTimerChannel.

• Added functions queuedSignalStream, queuedProcessorChannel and queuedChannelProcessor.

Version 4.6

• Removed the MonadTemplate type class as it often caused overlapping family data instances.

• Updated module DoubleLinkedList.

• Breaking change: arrows Net and Processor are trying to perform computations in parallel as possible, when using the proc notation. Earlier they executed sequentially.
