Deprecated and New features in Spring 19

Deprecated Default Values Without Square Brackets for Array, Set, and List Attributes

Setting a default value without square brackets is deprecated and can lead to unexpected behavior. To set a default value for these attribute types, surround comma-separated values with []; for example, default="['red', 'green', 'blue']".
Where: This change applies to orgs with Lightning components in Lightning Experience, Salesforce Classic, and all versions of the Salesforce app.
How: Here’s an example of attributes for an array, a list, and a set.
<aura:attribute name="colorArray" type="String[]" default="['red', 'green', 'blue']" />
<aura:attribute name="colorList" type="List" default="['red', 'green', 'blue']" />
<aura:attribute name="colorSet" type="Set" default="['red', 'green', 'blue']" />

Get Notified About Unsaved Changes






Notify the UI about unsaved changes in your component with the lightning:unsavedChanges Aura component. You can uselightning:unsavedChanges in standard and console navigation apps. You can then use a controller to save or discard the changes.



Where: This change applies to orgs with Lightning components in Lightning Experience, Salesforce Classic, and all versions of the Salesforce app.






Reference Asset Files with the $ContentAsset Global Value Provider






The $ContentAsset global value provider lets you reference images, style sheets, and JavaScript used as asset files in your Lightning components. Reference $ContentAsset asset files by name instead of using cumbersome file paths or URLs. $ContentAsset provides sharing, versioning, and access control for all asset files, as well as options for mobile optimization and resizing of image files. You can use $ContentAsset in Lightning components markup and within JavaScript controller and helper code.



Where: This change applies to Lightning Experience in Professional, Enterprise, Performance, and Unlimited editions.



How: To reference a specific asset file in component markup, use $ContentAsset.yourNamespace__assetName. Orgs without a namespace can use $ContentAsset.assetDeveloperName. Use this syntax regardless of whether an asset is for authenticated or unauthenticated sessions. To reference a content asset within an archive, add pathinarchive as a parameter appended to the basic syntax: $ContentAsset.yourNamespace__assetName + 'pathinarchive=images/sampleImage.jpg'.



Include cascading style sheets or JavaScript libraries in a component using the <ltng:require> tag.















The $ContentAsset global value provider doesn’t support versions or scaling parameters. Only the latest version of the asset file is served, and only the original size of the image is returned.

Maintain Your Platform Developer I Certification for Winter ’25

  Make Invocable Actions Easier to Configure with New InvocableVariable Modifiers Simplify the configuration of invocable actions using new modifiers from Salesforce. Both the defaultValue and placeholderText modifiers will appear in Flow Builder for the Action elements that correspond to an invocable method. Here’s how to use them. defaultValue Modifier : Set a default value for an input parameter. When the action is used, the input parameter will have a predefined value unless changed by the user. placeholderText Modifier : Set custom placeholder text for an input parameter. Text can provide examples or additional guidance to help users understand what to enter in the input field. Accessing these modifiers in Flow Builder makes it easier to configure and use the actions within your flows. This change applies to Lightning Experience and Salesforce Classic in Performance, Unlimited, Developer, Enterprise, and Database.com editions.

Platform App Builder Certification Maintenance (Winter '24)

 Maintain Your Platform App Builder Certification for Winter ’24 The Enable Reactive Components for Screen Flows running API Version 57.0 and 58.0 setting expires in Winter ’25. Before that release, upgrade your flows to run on API version 59.0 or later to take advantage of reactive components. Build Screen Flows with Reactive Global Variables Save time by referencing global variables in reactive formulas on flow screens. Use custom labels in reactive formulas to display translatable text to your users. For example, create a custom setting called DiscountPercentage, which specifies org, profile, and user discount percentages. Reference the variable in reactive formulas across a screen flow. The screen flow applies the correct discount value for the user running the flow and recalculates the value as the user makes changes.   Build Screen Flows with Reactive Selections Use choice components to respond to user selections elsewhere on the same screen. For example, on a flow ...
