ReleaseNotes

Release notes

Included in Modelica standard library 2.0 Beta 1 with the new block connectors. Changed all the references to the block connectors and the Logical library correspondingly.

New components "Alternative" and "Parallel" for alternative and parallel execution paths.
A step has now a vector of input and output connectors in order that multiple connections to and from a step are possible
Removed components "AlternativeSplit", "AlternativeJoin", "ParallelSplit" and "ParallelJoin" since the newly introduced components ("Alternative", "Parallel", vector connectors of steps) have the same modeling power but are safer and more convenient.
Removed the timer in a step (attach instead Logical.Timer to the "active" port of a "StepWithSignal" component). Note, that in most cases it is more convenient and more efficient to use the built-in timer of a transition.
Component "StepInitial" renamed to "InitialStep".
New component "Timer" within sublibrary Logical.
Updated and improved documentation of the library.

Renamed "MacroStep" to "CompositeStep" and the ports of the MacroStep from "abort" to "suspend" and "histoy" to "resume".
Nested "CompositeStep" components are supported, based on the experimental feature of nested inner/outer components introduced by Dymola. This means that CompositeSteps can be suspended and resumed at every level.
New example "Examples.ShowExceptions" to demonstrate the new feature of nested CompositeSteps.
New package "Logical". It contains all components of ModelicaAdditions.Blocks.Logical, but with new block connectors and nicer icons. Additionally, logical blocks are also added.
Improved icons for several components of the StateGraph library.

The "abort" and "history" connectors are no longer visible in the diagram layer of a CompositeStep since it is not allowed to connect to them in a CompositeStep.
Made the diagram/icon size of a CompositeStep smaller (from 200/-200 to 150/-150).
Improved icons for "SetBoolean/SetInteger/SetReal" components.
Renamed "ParameterReal" to "SetRealParameter".

Implemented a first version that is provided to other people.
