New:

• Added title parameter to options for showUI.
• Added use_absolute_bounds property for ExportSettings.

New:

• Added hyperlink property for TextNode. New methods getRangeHyperlink and setRangeHyperlink are also available for manipulating hyperlink targets.
• Added rotation property for ImagePaint.
• Added ON_KEY_DOWN type to Trigger.

New:

• Added documentationLinks property for ComponentNode and ComponentSetNode.
• Added detachInstance functionality for InstanceNode. This function preserves the same behavior as the equivalent functionality in the Figma editor.

New:

• Added swapComponent to swap an instance's main component to a different main component. This function preserves overrrides using the same heuristics as instance swap in the Figma editor UI.

New:

• Added commitUndo to commit new undo states to undo history. This does not trigger an undo.
• Added triggerUndo to trigger an undo action. This reverts to the last state in undo history.

New:

• Added moveLocalPaintStyleAfter, moveLocalTextStyleAfter, moveLocalEffectStyleAfter, and moveLocalGridStyleAfter to reorder local styles within folders.
• Added moveLocalPaintFolderAfter, moveLocalTextFolderAfter, moveLocalEffectFolderAfter, and moveLocalGridFolderAfter to reorder style folders that share the same parent folder.

New:

• Support for the new autolayout APIs! They are available on frame nodes.
• The primaryAxisSizingMode, primaryAxisAlignItems, counterAxisAlignItems properties have been added on frame-like nodes.
• The horizontalPadding and verticalPadding properties are now deprecated. Use paddingLeft, paddingRight, paddingTop and paddingBottom instead.
• The layoutGrow property has been added on all nodes (except documents & page nodes).
• The layoutAlign has changed. It now supports the values "STRETCH" | "INHERIT".

Fixed:

• The getPluginData and getSharedPluginData APIs now properly inherit from components when accessed from an instance.
• The setRelaunchData APIs is now able to override relaunch data on instances.

New:

• Support for Variants! This update comes with a new node type: learn more about component sets.
• New functions combineAsVariants and importComponentSetByKeyAsync to support variants.

Fixed:

• Fixed a bug where instance.children would not return any children when the instance was invisible
• Fixed a bug where setting a local style to private (by prepending _ to the style name) did not stop it from being published
• Fixed a bug where accessing textNode.textAutoResize would crash
• Fixed a bug where it was possible to give a node invalid coordinates by setting relativeTransform to some value where the two axes had zero dot product
• Fixed a bug where components imported from the team library became writeable
• Fixed a bug where figma.getLocal*Styles() would return an array containing null or invalid style nodes

New:

• enablePrivatePluginApi option in manifest.json to enable Private Plugin specific APIs
• For private plugins with the above option set, figma.fileKey will be set to the key of the current file.
• The ui property in the plugin manifest can now either contain a filename in the form of a string. Or a list of filenames in the form of a map.

// either
"ui": "ui.html"

// or
"ui": {
  "loginPage": "login.html",
  "main": "ui.html",
}

• If you use the former, the file is available through the __html__ property. If you use the latter, then the files are available through a new __uiFiles__ property (eg.__uiFiles__.loginPage, __uiFiles__.main etc)

Fixed:

• InstanceNode.mainComponent now returns null instead of raising an exception if the underlying component doesn't actually exist.
• setPluginData and setSharedPluginData now removes the the relevant entries when the value is set to the empty string "", which is the default value returned by getPluginData and getSharedPluginData.

New:

• The newly released easing curves are now available in the API.
• The existing reactions property returns multiple reactions to support this newly launched feature.
• The spread property in ShadowEffect to match the newly released spread feature.
• A rescale function to match to toolbar's Scale Tool.
• The masterComponent property has been renamed to mainComponent

Fixed:

• The QuickJS runtime used to sandbox plugin code has been upgraded to the latest version. Exceptions thrown will now contain a property stack trace (e.g. in the (new Error()).stack). Note that you could previously get stack traces using the Developer VM, which also supports the debugger keyword.
• The setSharedPluginData namespace argument now supports the characters _, . and uppercase characters.
• Fixed an issue where exportAsImage API would sometimes would fail to render nodes correctly due to instances not being updated.
• Fixed an issue where plugins could sometimes set a non-invertible affine transform to relativeTransform.
• Fixed an issue where cloning a component via .clone() would not trigger library updates for publishing.
• Fixed an issue where very long plugin names would stretch the plugin window.
