#### Added

* Support for Dynamic Grammar Resolution capability to [Update Resources][UpdateResourcesActivity] activity.
	* The activity can be configured to resolve / evaluate lookups and expressions in the values returned by the expressions in update definitions. e.g. The string returned by `[//Queries/EmailTemplate/EmailBody]` will be parsed and all lookups will be resolved.

#### Changed

* Use of [EvaluateExpression][EvaluateExpressionFunction] function will now log a deprecation warning in the event log in favour of using the newly implemented Dynamic Grammar Resolution capability of the [Update Resources][UpdateResourcesActivity] activity.

#### Fixed

* Error event logging logic in the [Run PowerShell Script][RunPowerShellScriptActivity] activity.

------------

### Version 2.16.0305.0

#### Added

* Support for dropping hard / soft signs and any other symbols in [NormalizeString][NormalizeStringFunction] function .

#### Changed

* [Run PowerShell Script][RunPowerShellScriptActivity] activity will now only abort the workflow execution when an unhandled or explicit exception is thrown from the PowerShell script. Non-terminating errors in the script will only get logged to the event log.

------------

### Version [2.16.0130.0] 

#### Added

* Support for executing a collection of Queries.
* New function `FormatMultivaluedList`.

### Version 2.16.0115.0

#### Added

* Support for "/" as a Null Query.

### Version 2.16.0110.0

#### Added

* Re-branded of FIMWAL "2" version 2.15.1016.0 as MIMWAL.

* Added design time check for the Activity Execution Condition to be a boolean function expression.
	* If in FIMWAL "2" you were using an `IIF` function expression as an Activity Execution Condition, you'll need to wrap it around a `ConvertToBoolean` for UI validation to succeed when making any changes to the activity in future.
* Added support to break iteration loop in `UpdateResources` and `CreateResource` activities.
	* Reserved `$__BREAK_ITERATION__` for the name of the boolean variable that needs to be set to true to break the iteration loop.
* Added support for cascaded queries lookup so that data from the first query can be used in the XPath search filter expression of the second query.

#### Changed

* Updated `Add` and `Subtract` function to treat null input values as zero instead of throwing exception
* Made substitutions parameter optional in `NormalizeString` function.

#### Removed
