GeneXus X	GeneXus X Evolution	Description
Interactive Activity	User	Task that will be executed by a user.
Batch Activity	Script	Task that will be automatically executed by the Workflow engine.
Subprocess	Reusable	Sub-process embedded in the current process.
Start	None	Start of the process (optional)
End	None	End of the process (optional)
Conditional	Inclusive	It indicates the evaluation of conditions to choose the route that will be followed. One or more routes can be taken.
Route Activity	None	This task is automatically executed by the Workflow engine and doesn't imply any action by the user. At design time it is considered a task that hasn’t been defined yet.
And Join	Parallel	It represents a synchronization point in which, in order to move forward with the flow, all tasks connected to this symbol have to be completed.
Choice Activity	Not supported (see note)

Note: When migrating a diagram that uses the Choice Activity symbol from one version to another, we have to generate optional routes from the symbol’s preceding task up to the subsequent tasks.

• Start and End Symbols

It is no longer necessary to use the start and end symbols in all workflow diagrams.
They are strictly required in the case below:

- The initial tasks of the process have input edges, that is to say, at some point of the process it is possible to return to the initial task.

• Nested Conditionals

It is no longer necessary to include a symbol of route activity type between nested conditionals.

• Workflow Context

It is no longer necessary to define the variables corresponding to the process instance, definition and work item.
To access the context the following code should be used:

&WorkflowContext.ProcessInstance
&WorkflowContext.ProcessDefinition
&WorkflowContext.Workitem

In addition, this context can be accessed from all the objects involved in the call chain.

• Deadlines

Now to represent a deadline you must use an intermediate event, the timer.
