Release Notes
Version 1.11
(July 2020)
The following features were added to ArcGIS Enterprise server 10.8.1, but not ArcGIS Enterprise portal 10.8.1. See version 1.10 for new features added to ArcGIS Enterprise portal 10.8.1.
Bitwise Operators
You can now use bitwise operators in Arcade expressions. The expression evaluates the operation based on the binary representation of numbers.
7 & 14
// binary 0111 & 1110, which results in 0110
// the expression will return 6
Template literals
Template literals allow for embedding expressions in text literals using the following syntax:
`Text is wrapped in backticks, and expressions ${ /* go inside curly braces preceded by a $ */ }.`
This allows for easier text manipulation in Arcade. For example, in Arcade 1.11 you can do this...
var textContent = `The average score was ${Round(Average(scores), 2)}%.`
...instead of text concatenation...
var textContent = "The average score was " + Round(Average(scores), 2) + "%".
Read the Template literals guide for more information and examples.

Version 1.5
(December 2018)
FeatureSet support in popups and attribute rules
FeatureSet is a new data type that gives you access to other features in the same layer, feature service, or map as the feature executing an Arcade expression. This functionality is only available in the Popup and Attribute Rule profiles.
We introduced three new global variables in these profiles:
$layer- A FeatureSet containing all features in the same layer as the$feature. This only applies to feature layers.$map- A collection of layers in the same map as the$feature.$datastore- A collection of layers in the same feature service as the$feature.
FeatureSets allow you to write expressions that return a result based on the feature's relationship with other features in the map. For example, you can compare the value of a feature's field to the statistics of the same field for all features in the layer.
// returns the difference between the feature's 'population' and the average value of `population` in the dataset
$feature.population - Mean($layer, 'population');
You can chain functions that support FeatureSet.
var sensitiveAreas = FeatureSetByName($map, 'Sensitive Land', ['LandType'], true);
var affectedLandPoly = Geometry($feature);
var countAreas = Count( Intersects( Filter( sensitiveAreas, "LandType='Arable'"), affectedLandPoly) );
You can also substitute Arcade variables in functions that take SQL92 expressions as a parameter using the @ character.
var averageValue = Average($layer, 'POPULATION');
var result = Filter($layer, 'POPULATION > @averageValue');

Version 1.4
(July 2018)
Casting Feature to Geometry
For your convenience, we added support for internally casting features to geometries in all geometry functions. That means you can directly pass a feature (e.g. $feature) to any parameter that
accepts Geometry types.
// At Arcade 1.4, you can pass a feature directly to any geometry
// function, which internally casts the feature as a geometry object
AreaGeodetic( $feature, 'square-meters' )
// This supersedes the previous workflow, which required you to
// cast the Feature to a Geometry yourself
// required syntax at Arcade 1.3
AreaGeodetic( Geometry($feature), 'square-meters' )
New profiles
Arcade expressions can now be executed in the following profiles:
These profiles allow you to write expressions for attribute rules in ArcGIS Pro.
New functions
Version 1.3
(December 2017)
Geometry operations
We added several new geometry functions that allow you to perform geometric operations in any of the following categories:
- Testing topological relationships
- Overlay
- Measurement
- Proximity
See the updated overview of Geometry Functions for more information and the new functions listed below.
Many of the geometry functions, such as the overlay and testing functions, require more than one input geometry. In the current release of Arcade, you can manually construct geometry objects as needed within the expression. For example, you can calculate the distance from one hard-coded point to all points in a layer. In a future release, we will provide methods that allow you to access other geometries within the same layer and features in other layers.

Version 1.2
(September 2017)
New functions
Version 1.1
(June 2017)
Popup profile
The popup profile was added, allowing users to define expressions that will evaluate and display values calculated on the client when the popup displays in the view. Users can reference Arcade expressions with placeholders that will be replaced by expression values when the popup is opened. See the individual ArcGIS SDKs for examples of how this works within applications.
