<h2 id="2.1">GoJS 2.1</h2>
<h3>New Animation Capabilities</h3>
<p>GoJS 2.1 contains a number of new features to animate different components of your Diagram.</p>
<div style="margin-top: 30px; margin-bottom: 30px;">
<img src="assets/images/changelog/2.1nodeAnimation.gif" style="width: 150px;">
<img src="assets/images/changelog/2.1linkAnimation.gif" style="margin-left: 100px; width: 200px;">
</div>
<p>
See the <a href="intro/animation.html" target="_blank">Intro page on Animation</a> and the <a href="samples/customAnimations.html"
target="_blank">Custom Animation sample</a> for more details and examples.
</p>
<ul>
<li>
New default GoJS animation "fades up", instead of animating Node locations. Added <a>AnimationManager.initialAnimationStyle</a>
to control this behavior.
Here is an example of:
<ul>
<li>(top) The new initial animation, the Diagram position animating upwards and Diagram opacity animating
from 0 to 1.
<li>(middle) A custom "zoom in" animation, animating Diagram scale, which is demonstrated in the new <a href="samples/stateChart.html"
target="_blank">State Chart</a> sample,
<li>
(bottom) <a>AnimationManager.initialAnimationStyle</a> set to <a>AnimationManager.AnimateLocations</a> to
perform the GoJS 2.0 and previous style of animation.
The <a href="samples/dataVisualization.html" target="_blank">Data Visualization</a> sample uses this
option.
</ul>
<p>
<img src="assets/images/changelog/2.1initalAnimation.gif" style="margin-left: 10px; width: 250px;">
</p>
</li>
<li>
Added <code>"InitialAnimationStarting"</code> <a>DiagramEvent</a> to more easily customize initial animations.
See <a>AnimationManager.initialAnimationStyle</a> for details.
</li>
<li>
New class: <a>AnimationTrigger</a>. These describe how to automatically animate a property on a GraphObject
when it changes value.
</li>
<li>
New class: <a>Animation</a>. This class lets you declaratively setup custom animations, with options for
indefinite animations.
</li>
<li>
New <a>AnimationManager</a> options, including the ability to define custom animation effects to animate with
<a>AnimationManager,defineAnimationEffect</a>
</li>
<li>
New Animation samples and samples modified to use new Animation features:
<ul>
<li><a href="samples/customAnimations.html" target="_blank">Custom Animation</a> - <strong>New Sample:</strong>
Demonstrating a number of Node creation/deletion animations, linking animations, and more.</li>
<li><a href="samples/treeLoadAnimation.html" target="_blank">Tree Load Animation</a> - <strong>New Sample:</strong>
recursive animation upon model load.</li>
<li><a href="samples/flowchart.html" target="_blank">Flowchart</a> - In the Palette only, initial animation
is disabled in favor of a custom fade-in animation.</li>
<li><a href="samples/stateChart.html" target="_blank">State Chart</a> - Initial animation is disabled in
favor of a custom zoom fade-in animation.</li>
<li><a href="samples/dataVisualization.html" target="_blank">Data Visualization</a> - Nodes now move using an
<a>AnimationTrigger</a>.</li>
<li><a href="samples/kittenMonitor.html" target="_blank">Kitten Monitor</a> - Kittens now move using an <a>AnimationTrigger</a>.</li>
<li><a href="samples/processFlow.html" target="_blank">Process Flow</a> - An indefinite Animation of the
Links' strokeDashArray.</li>
<li><a href="samples/shopFloorMonitor.html" target="_blank">Shop Floor Monitor</a> - Link color changes now
use an <a>AnimationTrigger</a>.</li>
</ul>

<h3>Improved Support For Data Synchronization</h3>
<p>GoJS 2.1 contains some new methods to ease integration of GoJS diagrams in applications that maintain their own
data, particularly React apps.</p>
<p>
See the <a href="intro/react.html" target="_blank">Intro page on using GoJS with React</a> and the <a href="https://github.com/NorthwoodsSoftware/gojs-react-basic"
target="_blank">gojs-react example project</a> for details and examples.
Also see <a href="https://github.com/NorthwoodsSoftware/gojs-react" target="_blank">gojs-react</a>, a package
containing React Components for GoJS Diagrams, Palettes, and Overviews.
</p>
<ul>
<li>
New method: <a>Model.toIncrementalData</a>. This method outputs an <a>IncrementalData</a> object containing
changes that occurred within a <a>Transaction</a>,
similar to the existing method, <a>Model.toIncrementalJson</a>. It can be used to keep outside data
synchronized with the GoJS model.
</li>
<li>
New methods: <a>Model.mergeNodeDataArray</a> and <a>GraphLinksModel.mergeLinkDataArray</a>. These methods are
used to merge outside data changes into the GoJS model.
</li>
<li>
New method: <a>Model.cloneDeep</a>. This method can be used to make a deep copy of an object, which may be
useful to ensure GoJS doesn't share references with outside state.
It is also used within <a>Model.toIncrementalData</a> to ensure <a>IncrementalData</a>'s list of modified
objects won't contain references to the model's data objects.
</li>
</ul>
<h4>Changes for 2.1.4</h4>
<ul>
<li>
Added <a>Link.computeAdjusting</a> to conditionally change the value of <a>Link.adjusting</a> used. As a new default,
links will use the adjusting value <a>Link,End</a> during animation. <a>Link.computeAdjusting</a> can be overriden to change this behavior.
</li>
<li>
Added <a>Geometry.getPointAlongPath</a>, <a>Geometry.getAngleAlongPath</a>, and <a>Geometry.getFractionForPoint</a>.
These methods can be used to find a point or angle for a given fractional distance along a Geometry's path,
or to find the fractional distance along the Geometry's path given a nearby point.
</li>
<li>
Setting <a>GraphObject.segmentIndex</a> to NaN, which was previously an error, will now treat the entire link path as the segment
for the purpose of <a>GraphObject.segmentFraction</a>. This allows for getting fractional distances along the entire link.
</li>
<li>
Fix for object picking during Diagram's InitialLayoutCompleted DiagramEvent.
</li>
<li>
Fixed a bug in GoCloudStorage where a null defaultModel would fail.
</li>
<li>
Fixed a bug in <a>Panel.graduatedValueForPoint</a> in cases where the main shape was a diagonal line
and the provided point didn't fall on the line.
</li>
</ul>
<h4>Changes for 2.1.3</h4>
<ul>
<li>
Fixed a regression (that started in 2.0.0) with AvoidsNodes links improperly re-routing when using the
DraggingTool.
</li>
<li>
Fixed a undo (redo) bug with <a>AnimationTrigger</a>s that used location or position on Parts.
</li>
<li>
Improved routing of duplicate links that have <a>Link.adjusting</a> set to a value other than None and have
more than the standard number of points in their route.
</li>
</ul>
<h4>Changes for 2.1.2</h4>
<ul>
<li>
Fixed a regression in 2.1.1 with the timing of <code>InitialAnimationStarting</code> that would prevent custom
initial animations.
</li>
<li>
CTRL + Mouse-wheel will still stop the event from bubbling, even if <a>CommandHandler.canIncreaseZoom</a> or <a>CommandHandler.canDecreaseZoom</a>
are false.
These are potentially false if a <a>Diagram.minScale</a> or <a>Diagram.maxScale</a> are set.
This change stops the entire page from accidentally zooming during a zoom-wheel operation.
</li>
<li>
Fixed a measuring bug with Link Geometry when the Link is smaller than the <a>Link.toShortLength</a> or <a>Link.fromShortLength</a>.
</li>
</ul>
<h4>Changes for 2.1.1</h4>
<ul>
<li>
Fixed updating of <a>Adornment</a>s when there are <a>Binding</a>s from <a>Model.modelData</a>
and that shared object has been modified by calling <a>Model.set</a>.
</li>
<li>
Improved performance when replacing <a>Diagram.model</a> when cleaning up the old model,
which had infrequently resulted in obscure warnings in debug mode about <a>Node.isTreeLeaf</a>.
</li>
<li>
Fixes for loading Models with serialized EnumValues.
</li>
<li>
Performance improvements for concurrent animations.
</li>
<li>
Fixes for consistency of animation state.
This includes modifying when <code>AnimationStarting</code> and <code>InitialAnimationStarting</code> are
called,
and fixes when default animations are stopped and another is immediately started, such as when loading a new
model in the middle of animation.
</li>
<li>
Fixed <a>Model.fromJson</a> loading models with serialized EnumValues.
</li>
<li>
Improved showing non-default cursors when dragging between diagrams.
</li>
<li>
Fixed the operation of <a>Diagram.handlesDragDropForTopLevelParts</a> when dragging on the elements of a <a>Group</a>.
</li>
<li>
Fixed a bug where <a>Diagram.scrollHorizontalLineChange</a> and <a>Diagram.scrollVerticalLineChange</a> would
not affect scrolling size in some browsers.
</li>
<li>
Fixed a bug where some AvoidsNodes Links would not route properly in nested groups.
</li>
</ul>
<h4>Other Changes for 2.1.0:</h4>
See the major changes <a href="#2.1">above</a>.
<ul>
<li>
Added <a>DoubleTreeLayout</a> to the extensions and extensionsTS directories. This is now used by both the
<a href="../samples/doubleTree.html">Double Tree</a> and <a href="../samples/doubleTreeJSON.html">Double Tree
JSON</a> samples.
</li>
<li>
Updated the sequencing of "ChangingSelection" and "ChangedSelection" <a>DiagramEvent</a>s to be outside of
transactions for commands and tools.
Exceptions include "ChangingSelection" being called during "Drag" and "Linking" operations when drag-copying or
inserting a link.
With "ChangedSelection" occuring after a transaction completes, any changes will be complete and can be used in
the listener.
</li>
<li>
<a>CommandHandler.zoomToFit</a> now animates by default.
</li>
<li>
Improved the <a>ContextMenuTool.defaultTouchContextMenu</a>'s "Paste" command to use the <a>ContextMenuTool.mouseDownPoint</a>
rather than the <a>Diagram.lastInput</a>'s <a>InputEvent.documentPoint</a>.
</li>
<li>
Added new property, <a>Diagram.opacity</a>. This may be useful for fade-in/out animations, or visual indication
of a disabled Diagram.
</li>
<li>
Added new method, <a>Diagram.findLinkForKey</a>, which will look for a link corresponding to a model's link
data object's unique key.
This will only return a link when using a <a>GraphLinksModel</a> with <a>GraphLinksModel.linkKeyProperty</a>
set to a non-empty string.
</li>
<li>
<a>Model.applyIncrementalJson</a> now throws an error if model properties (eg. nodeKeyProperty) included in the
JSON don't match the existing model.
This check only includes properties included in the output from <a>Model.toIncrementalJson</a>.
</li>
<li>
Added new methods, <a>Picture.reload</a>, which reloads a Picture source in case the file on the server has
changed,
and <a>Picture.redraw</a> which redraws the picture, and can be useful to update the Picture if the source is
backed by an HTML Canvas or HTML Video Element.
</li>
<li>
Added new samples:
<ul>
<li><a href="samples/svgDataUrl.html" target="_blank">SVG Data URL</a> - Export SVG with Base64 hrefs instead
of the Picture.source URL</li>
</ul>
</li>
</ul>
<hr />
<h3>GoJS 2.0</h3>
<p>
For 2.0, GoJS has been rewritten in TypeScript, with improvements to stability and documentation.
All customers (with or without source code license) can take advantage of the TypeScript definitions <code>.d.ts</code>
file,
which is much more comprehensive in 2.0.
</p>
<p>
A source license will now include TypeScript source files as well as JavaScript sources,
and examples of how to build the library into your project with Webpack or Browserify,
should you wish to. This will allow you to remove unused modules from the source code,
such as Layouts, Models, and Tools that you are not using. Note that unless you have strong minification,
you may not see size improvements over the pre-built <code>go.js</code> library, which is highly optimized.
</p>
<p>
The size of the <code>go.js</code> library has been slightly reduced (both uncompressed and gzipped), from 1.8
versions.
</p>
<p>
The main library has been reduced by removing many of the uncommon figures. These are now an extension. (<a href="extensions/Figures.js"
target="_blank">Figures.js</a>)
</p>
<p>
GoJS can now be run DOM-less, in Node.
</p>
<p>
We have added the ability to create your own Panels, with the new PanelLayout class. See an example <a href="samples/panelLayout.html"
target="_blank">here</a>.
</p>
<h4>Changes for 2.0.18</h4>
<ul>
<li>
Shapes with a shadow and a <a>Shape.fill</a> value of <code>"transparent"</code> now apply the shadow to the <a>Shape.stroke</a>,
instead of the invisible <a>Shape.fill</a>.
</li>
<li>
Minor scrollbar fixes.
</li>
<li>
Fixed "PanelExpanderButton" click event handler to set <a>InputEvent.handled</a> to true, so that other click
event handlers in containing panels will not run.
</li>
<li>
Improved the <a>Map</a> constructor and <a>Map.addAll</a> method to accept an instance of <a>Map</a>.
</li>
</ul>
<h4>Changes for 2.0.17</h4>
<ul>
<li>
Fixed a bug with scrollbars when setting invisible/hidden Diagram DIVs to visible/unhidden while modifying
their size.
</li>
<li>
Improved orthogonal link segment overlap avoidance in <a>LayeredDigraphLayout</a>.
</li>
<li>
Optimizations for Puppeteer.
</li>
</ul>
<h4>Changes for 2.0.16</h4>
<ul>
<li>
IE bugfix when dragging from a Diagram or Palette and dropping on a non-Diagram page element.
</li>
<li>
Fixed the <a>DraggingTool</a>, when moving or copying between diagrams, to update the <a>Diagram.currentCursor</a>
to be the <a>Diagram.defaultCursor</a>, not to "default".
</li>
<li>
Fixed a bug when setting <a>AnimationManager.isInitial</a> to <code>false</code> when there are no Parts in the
initial model.
</li>
</ul>
<h4>Changes for 2.0.15</h4>
<ul>
<li>
Link JumpOver fixes.
</li>
<li>
Fixed an animation bug where some Model loading events might not respect the value of <a>AnimationManager.isInitial</a>.
</li>
<li>
Fixed a bug with <a>AnimationManager.isInitial</a>, where subsequent animations may not occur when it is false.
</li>
<li>
Fixed a bug with Picture drawing when the Picture is scaled to be drawn smaller than a pixel.
During expanding animations, it is possible that such a small scale is applied to a Picture.
</li>
</ul>
<h4>Changes for 2.0.14</h4>
<ul>
<li>
Added <a>DraggingOptions.groupsAlwaysMove</a>,
which determines whether Groups move their member parts even if those members have.
<a>Part.movable</a> and <a>Part.copyable</a> set to false.
</li>
<li>
Improved the way Graduated panels decide whether or not to draw ticks based on <a>Diagram.scale</a>.
It is now based on the approximate pixel distance between ticks.
If they would be rendered too close together, they will be skipped.
</li>
<li>
Fixed an infinite loop bug with <a>ContextMenuTool</a> when invoked by <a>CommandHandler.showContextMenu</a> on
a <a>GraphObject.click</a> event.
</li>
<li>
Minor fixes for using GoJS within Puppeteer, for making SVG.
</li>
</ul>
<h4>Changes for 2.0.13</h4>
<ul>
<li>
When dragging over a different Diagram than the source, such as in a drag from a Palette,
the DraggingTool now checks the Diagram's cursor and only changes it to <code>"copy"</code>
if the <a>Diagram.currentCursor</a> value is <code>""</code> or <code>"auto"</code>.
</li>
<li>
Drawing fix for some objects disappearing when rotated, and the Diagram is scaled.
</li>
<li>
Optimized <a>Group.move</a> not to try moving member parts when the offset is zero.
This improves the stability of layouts that move groups, such as PoolLayout in some samples.
</li>
<li>
<strong style="color:red;">This bugfix potentially breaks old <code>elementFinished</code> code in Shape
geometries with multiple figures.</strong>
Fix for <a>Diagram.makeSVG</a> <code>elementFinished</code> optional argument:
Shapes with multiple geometry figures would pass the final SVG <code><path></code> generated as the SVG
element,
when they should be grouped together and pass an SVG <code><g></code> instead.
This is what TextBlock already does when there is more than one line of text.
</li>
</ul>
<h4>Changes for 2.0.12</h4>
<ul>
<li>
Fixed a memory leak with internal <a>Picture</a> caching when modifying Panel item arrays.
</li>
<li>
Fixed animation when expanding and collapsing during Diagram load.
</li>
<li>
Fixed drawing in IE when drawing shapes with zero width or height geometries that have a stroke.
</li>
<li>
The <a>DraggingTool</a> will no longer auto scroll the diagram if <a>Diagram.isReadOnly</a> is true or both <a>Diagram.allowMove</a>
and <a>Diagram.allowCopy</a> are false.
This means that, by default, a <a>Palette</a> will no longer auto scroll while the DraggingTool is active.
</li>
<li>
Improved positioning of unrotated link labels when <a>GraphObject.segmentOffset</a> is <code>go.Point(NaN, NaN)</code>
and the link segment is more vertical than horizontal.
</li>
</ul>
<h4>Changes for 2.0.11</h4>
<ul>
<li>
Fixed a bug with <a>CommandHandler.standardMouseOver</a> mis-reporting the current object, a regression from
2.0.10.
</li>
</ul>
<h4>Changes for 2.0.10</h4>
<ul>
<li>
Fixed a bug with simulated <a>InputEvent</a>s, such as used by <a>Robot</a>, that caused <a>GraphObject.mouseEnter</a>
and <a>GraphObject.mouseLeave</a> event handlers not to be called.
</li>
<li>
The <a>Diagram.model</a> setter and <a>Diagram.clear</a> now call <a>Diagram.clearSelection</a> and <a>Diagram.clearHighlighteds</a>.
This provides a more uniform protocol of selection events.
</li>
<li>
Fixed a bug that would prevent some <a>Picture.successFunction</a>s from ever firing.
</li>
<li>
Fixed a bug with Bezier link routing in <a>LayeredDigraphLayout</a> when <a>LayeredDigraphLayout.setsPortSpots</a>
was false
and an end of the link was undirected.
</li>
<li>
Fixed a performance bug with Picture caching, introduced in 2.0.5.
</li>
</ul>
<h4>Changes for 2.0.9</h4>
<ul>
<li>
<a>Diagram.makeSvg</a> now accepts <code>callback</code> and <code>callbackTimeout</code> options. This makes
it more like
<a>Diagram.makeImage</a> and <a>Diagram.makeImageData</a> (which have had these options since 2.0.0).
If a callback function is provided, the methods will instead return null
and SVG creation will wait until all Diagram Picture sources are loaded
before creating the SVG and invoking the callback.
</li>
<li>
Fixed a regression with <a>Diagram.makeSvg</a> where it would not draw Pictures that were not yet loaded, even
if they had a valid size.
</li>
<li>
Fixed <a>GridLayout</a>s when used as a <a>Group.layout</a> and when <a>GridLayout.alignment</a> is <code>go.GridLayout.Position</code>,
to treat <a>GridLayout.wrappingWidth</a> as a width limit, regardless of the <a>Layout.arrangementOrigin</a>.
If you were forced to set <a>GridLayout.wrappingColumn</a> to a value just to be free of the treatment of the
default value for <a>GridLayout.wrappingColumn</a>
(<code>NaN</code>) to indicate the width of the viewport, it is now possible to set <a>GridLayout.wrappingWidth</a>
to respect a smaller value.
</li>
<li>
Fixed maintaining the selection state of selected Parts that change their category.
</li>
<li>
GoJS will step down the Canvas resolution during drawing operations like dragging and panning, which can lead
to "fuzzy" shapes and text during these operations.
This is now only done when a slower frame rate is detected.
</li>
<li>
Drawing performance improvements, especially in well-connected graphs.
</li>
<li>
Fixed a bug with trackpad scrolling reversing at the end of scroll events.
</li>
<li>
Fixed a bug drawing grids on some <a>Overview</a>s.
</li>
</ul>
<h4>Changes for 2.0.8</h4>
<ul>
<li>
Fixed a regression with Pictures from 2.0.4 that would throw an error when setting <a>Picture.source</a>.
</li>
<li>
Fixed potential errors in <a>Binding.ofObject</a> bindings when changing category/template because the bindings
were being evaluated on the copied new template rather than on the original Part.
</li>
</ul>
<h4>Changes for 2.0.7</h4>
<ul>
<li>
Floorplanner 2.0 - New Floorplanner project (<a href="projects/floorplannerTS/floorplannerTSSample.html">see it
here</a>), written in TypeScript, at <code>projects/floorplannerTS</code>. New features include:
<ul>
<li>
Wall mitering, with updated dimension links and angle nodes to account for this
</li>
<li>
The ability to define rooms, complete with name, floor type, area, and draggable labels
</li>
<li>
Textures - apply seamless textures to furniture or floors, by use of GoJS Pattern Brushes
</li>
<li>
Full integration with the GoCloudStorage library (save to Local Storage / Google Drive / Dropbox /
OneDrive)
</li>
<li>
Export to PNG
</li>
<li>
Export to SVG
</li>
<li>
Ability to define unit scale in Options menu
</li>
</ul>
</li>
<li>
New intro page on <a href="intro/replacingDeleting.html">Replacing Diagrams and Models</a>
</li>
<li>
Fixed a bug with Link Shape Geometries not rendering when updated partially off-screen.
</li>
<li>
Fixed a bug with <a>InputEvent.clickCount</a>: Before, on touch devices, this count was incremented only on the
end of the touch, and not the start.
This was discrepant from mouse click behavior, and would lead to problems when Tools queried the clickCount on
touch/mouseDown,
when determining for instance if a particular InputEvent was a double-click. Now, the <a>InputEvent.clickCount</a>
is reported consistently
on mouseDown/touchStart/pointerDown and the corresponding "up" events.
</li>
<li>
GoJS previously would set the Canvas Context's imageSmoothingEnabled property to false.
It no longer does this. If this change causes visual errors, please contact us.
</li>
</ul>
<h4>Changes for 2.0.6</h4>
<ul>
<li>Fixed a bug with the <code>go.d.ts</code> file where <a>GraphObject.alignment</a> was missing.</li>
<li>
Added missing cloneProtected overrides for <a>BalloonLink</a> and <a>DimensioningLink</a> so data is properly
copied.
</li>
</ul>
<h4>Changes for 2.0.5</h4>
<ul>
<li>
Fix for <a>Shape,defineFigureGenerator</a> where it would incorrectly throw an error on Geometry bounds being
too large, when they were not.
</li>
<li>
Some touch events would cause [intervention] warnings in some browsers when canceled because GoJS would call
<code>preventDefault</code> on non-cancelable events.
This has been fixed.
</li>
<li>Fixed a bug with <a>Diagram.zoomToFit</a> when <a>Diagram.scrollMode</a> was set to <a>Diagram,InfiniteScroll</a>.</li>
<li>Fixed a bug where <a>GuidedDraggingTool</a> was snapping the whole part to a guideline instead of the
location object.</li>
</ul>
<h4>Changes for 2.0.4</h4>
<ul>
<li>
Fixed the TypeScript declaration of <a>GraphObject,make</a> to allow an <code>HTMLDivElement</code> as an
argument when building a <a>Diagram</a>.
Also added some type overloads of that function to reduce apparent type errors with correct code.
</li>
<li>
Fixed some apparent non-determinism in the results of <a>LayeredDigraphLayout</a> upon an initial layout.
</li>
<li>
Animation upgrades, notably when you move a port during an animation, connected Links will properly re-route.
</li>
</ul>
<h4>Changes for 2.0.3</h4>
<ul>
<li>
Improved data binding of tooltips and context menus for item panels to avoid temporarily setting <a>Panel.data</a>
incorrectly.
</li>
<li>
Enhanced the meaning of <a>UndoManager.maxHistoryLength</a> so that a value of zero causes no <a>Transaction</a>s
to be
remembered in the <a>UndoManager.history</a> but allows commits and rollbacks to occur normally.
</li>
<li>
Fixed a bug from 2.0.1 with <a>Diagram.makeSvg</a> incorrectly re-using SVG elements.
</li>
<li>
Fixed a bug from 2.0.0 with <a>Diagram.makeSvg</a> when drawing dashed paths.
</li>
<li>
Deployment fixes for electron apps.
</li>
</ul>
<h4>Changes for 2.0.2</h4>
<ul>
<li>
Updated the <a href="samples/canvases.html">Charts in Nodes sample</a> to use <a href="https://chartjs.org">Chart.js</a>.
</li>
<li>
Deployment fixes. This release should resolve <em>"Cannot use 'in' operator to search for 'go' in undefined"</em>
errors in some browser contexts.
</li>
</ul>
<h4>Changes for 2.0.1</h4>
<ul>
<li>
TypeScript declarations: we have created the <a>ObjectData</a> interface, defined as <code>{ [index: string]: any; }</code>,
to allow easier manipulation of data Objects, mostly in Models and change notification.
Many methods and properties now use <code>ObjectData</code> instead of <code>Object</code> in the <code>go.d.ts</code>
file.
The compiled JavaScript is unchanged by these better type declarations.
</li>
<li>
We have added interface declarations for the "options" argument to
<a>Diagram.makeImage</a>, <a>Diagram.makeImageData</a>, and <a>Diagram.makeSvg</a>.
Also we have added more precise declarations replacing the <code>string</code> type for arguments to
<a>Diagram.addDiagramListener</a>, <a>Diagram.removeDiagramListener</a>, <a>Diagram.scroll</a>,
and for the properties
<a>Shape.strokeCap</a>, <a>Shape.strokeJoin</a>, and <a>TextBlock.textAlign</a>.
JavaScript calls to these methods are unchanged by these better type declarations.
</li>
<li>
We have improved the declarations for <a>GraphObject,make</a>.
You may find that you will need to cast the result of calling this function or pass a result type when the
first argument is a string. For example:
<code>$(go.Node, . . ., { contextMenu: $<go.Adornment>("ContextMenu", . . .) }, . . .</code>.
Also, you may find that event handlers need to have precise type declarations for the arguments. For example:
<code>$(go.Node, . . ., { click: function(e: go.InputEvent, node: go.GraphObject) { . . .} }, . . .</code>.
JavaScript calls to this function are unchanged by the better type declarations for <a>GraphObject,make</a>.
</li>
<li>
The HTML Divs created for the default context menu now have CSS class names: 'goCXforeground' and
'goCXbackground'.
The HTML textarea for the TextEditingTool now has the CSS class name: 'goTXarea'.
</li>
<li>
When supplied with an argument, <a>CommandHandler.expandTree</a>, <a>CommandHandler.collapseTree</a>,
<a>CommandHandler.expandSubGraph</a>, and <a>CommandHandler.collapseSubGraph</a>
incorrectly operated on the <a>Diagram.selection</a> if the argument Part was already in an expanded/collapsed
state.
This has been fixed not to do so.
</li>
<li>
Performance improvements with JumpOver/JumpGap Links.
</li>
<li>
Fixed a bug with inappropriate invalidation of link routes when a Group was moved.
</li>
<li>
Fixes for SVG rendering of Pattern brushes.
</li>
</ul>
<h4>Changes for 2.0</h4>
<ul>
<li>
<b>Build GoJS from TypeScript Source:</b>
<p>
GoJS can be compiled from the TypeScript source files.
Dynamically building GoJS this way allows unused modules/code to be removed.
See the new Intro page on <a href="intro/source.html">Building GoJS from TypeScript sources</a>
</p>
</li>
<!-- don't document yet
<li>
<b>GoJS can now be loaded as an ES6 Module:</b>
<p>
GoJS can be used as a module with <code><script type="module"></code> tags.
This requires using the <code>go-module.js</code> or <code>go-debug-module.js</code> builds,
which uses <code>export const go</code>. There is an example in the <code>/samplesTS</code> directory,
<a href="samplesTS/minimalModule.html">minimalModule.html</a>.
</p>
</li>
-->
<li>
<b>GoJS now runs in DOM-less environments like Node:</b>
<p>
GoJS can run in DOM-less environments, like Node, without any dependencies.
See the new Introduction page on <a href="intro/nodeScript.html">GoJS with Node.js</a>.
</p>
<p>
GoJS cannot guarantee accurate Picture and TextBlock measuring in DOM-less environments,
so if you do not set <code>desiredSize</code> (or <code>width</code> <em>and</em> <code>height</code>) on
TextBlocks or Pictures,
you may want to use GoJS inside of a headless browser project, like Chrome's Puppeteer.
We detail how to use GoJS with Puppeteer in the <a href="intro/serverSideImages.html">Server Side Images</a>
Introduction page.
</p>
<p>
DOM-less environments can be used for server-side work, such as computing complex layouts.
Headless environments such as Puppeteer can be used to do layout calculations or to make
<a href="intro/serverSideImages.html">server-side images of Diagrams</a>.
</p>
<!-- Undocumented
<p>
DOM-less environments can be forced by calling <a>Diagram,useDom</a> with <code>false</code> as the argument.
</p>
-->
<p>See the note about <a>Diagram.viewSize</a> below.</p>
</li>
<li>
<b>Reworked part-moving and added a new class: <a>DraggingOptions</a>:</b>
<p>
<a>DraggingOptions</a> holds properties for Part-moving operations, and
<a>DraggingInfo</a> holds relative positions of dragged objects, for use in snapping and cancellation.
The <a>DraggingTool</a> has an instance of the DraggingOptions class, and
setting properties like <a>DraggingTool.isGridSnapEnabled</a> modifies this instance.
If the Diagram has no DraggingTool associated with it, it falls back to the default properties of the class.
You can create your own to pass to part-moving methods.
Typically you do not need to create an instance of this class.
</p>
<p>
Moving parts has been reworked. <a>Diagram.moveParts</a>, <a>Diagram.computeMove</a>, and
<a>CommandHandler.computeEffectiveCollection</a> now accept
an additional argument for a <a>DraggingOptions</a> instance.
This allows fine-grained control over programmatic moving of nodes.
Typically, these options are supplied by the <a>DraggingTool.dragOptions</a> instance.
</p>
<p>
<a>DraggingTool.computeMove</a> functionality has been moved to <a>Diagram.computeMove</a>,
and <a>DraggingTool.computeEffectiveCollection</a> functionality has been moved to <a>CommandHandler.computeEffectiveCollection</a>.
These methods remain on their original class for compatibility when overriding,
but the main functionality has been moved to the Diagram class for tree-shaking reasons.
</p>
</li>
<li>
<b>Diagram and Layer:</b>
<ul>
<li>
Added <a>Diagram.mouseEnter</a> and <a>Diagram.mouseLeave</a> to allow for functions to be called on
mouseenter and mouseleave events
on the Diagram's Canvas element.
</li>
<li>
When mouse leaves a Diagram, <a>Diagram.lastInput</a> is now set to the "mouseout" MouseEvent.
</li>
<li>
Added <code>"GainedFocus"</code> and <code>"LostFocus"</code> <a>DiagramEvent</a>s,
which allow functions to be called when the Diagram's canvas gains or loses focus,
without having to access any of the DOM within the <a>Diagram.div</a>.
</li>
<li>
Added <a>Diagram.findPartsAt</a>, <a>Diagram.findPartsIn</a> and <a>Diagram.findPartsNear</a> as
convenience functions.
These functions call <a>Diagram.findObjectsAt</a>, <a>Diagram.findObjectsIn</a> or <a>Diagram.findObjectsNear</a>
and only return Parts in non-temporary layers, rather than all GraphObjects.
</li>
<li>
Added <a>Diagram.viewSize</a> which can be used to set a viewport size in DOM-less environments.
See the new <a href="intro/nodeScript.html">Intro page on GoJS with Node.js</a>.
</li>
<li>
Added <a>Diagram.handlesDragDropForTopLevelParts</a> which determines whether drag-and-drop events
may be bubbled up to the diagram if not handled by a Part.
</li>
<li>
<a>Diagram.moveParts</a>, <a>Diagram.copyParts</a>, and <a>Diagram.computePartsBounds</a> now accept an
Array of parts,
in addition to their former iterable collection of Parts.
</li>
<li>
<a>Diagram.makeImage</a> and <a>Diagram.makeImageData</a> now accept <code>callback</code> and <code>callbackTimeout</code>
options.
If a callback function is provided, the methods will instead return null
and image creation will wait until all Diagram Picture sources are loaded
before creating the image and invoking the callback.
</li>
<!-- Undocumented
<li>
Added static function <a>Diagram,isUsingDom</a>, which returns true if Diagrams are using a DOM, false otherwise,
and <a>Diagram,useDom</a>, which sets whether or not GoJS should use a DOM if one is available.
</li>
-->
</ul>
</li>
<li>
<b>Models:</b>
<ul>
<li>
Added property <a>Model.copiesKey</a> which controls whether <a>Model.copyNodeData</a> and <a>GraphLinksModel.copyLinkData</a>
copy any key property of the data.
Setting this to false is useful in forcing copies from a <a>Palette</a> to get a new unique key.
The default value is true for compatibility with version 1.*.
</li>
<li>
Improved <a>Model.updateTargetBindings</a> and <a>Part.updateTargetBindings</a> to update <a>Panel</a>s
that have
<a>Panel.itemArray</a> data bound if the contents of the Array have changed.
In version 1, the reference to the Array had to have changed -- the <a>Panel.itemArray</a> had to have been
replaced.
In version 2, the <a>Panel.itemArray</a> property setter checks to see if all of the Array items have
corresponding Panels
and that all child Panels correspond to Array items (i.e. <a>Panel.data</a> refers to the Array item),
even if the new property value is a reference to the same Array that it had been before.
</li>
</ul>
</li>
<li>
<b>Parts:</b>
<ul>
<li>
Added <a>Part.rotationSpot</a> to control the Spot within the <a>Part.rotateObject</a>
that the <a>RotatingTool</a> will pivot about.
</li>
<li>
<a>Part.move</a> and <a>Part.moveTo</a> now have an additional optional boolean argument
to specify moving by location instead of position.
</li>
</ul>
</li>
<li>
<b>Panels and PanelLayout:</b>
<ul>
<li>
Spot Panels now allow child elements to stretch, which will match the size of the main element.
<a href="intro/panels.html#StretchingWithSpotPanels" target="_blank">See the Intro Page for an example.</a>
</li>
<li>
It is now possible to create your own Panel layouts with the <a>PanelLayout</a> class. This is expected to
be very uncommon,
but may serve uncommon use cases. See the <a href="samples/panelLayout.html">PanelLayout sample</a> for an
example.
There is a new static function, <a>Panel,definePanelLayout</a> for this purpose.
</li>
<li>
When building from source, it is also possible to exclude many Panel types that you are not using, to make
the resulting JS smaller.
See the <a href="intro/source.html">Intro page on building GoJS sources</a> for details.
</li>
</ul>
</li>
<li>
<b>GraphObjects and Geometry:</b>
<ul>
<li>
<a>GraphObject.cloneProtected</a> is now documented. It functions in a similar
fashion to <a>Model.cloneProtected</a> and <a>Layout.cloneProtected</a>,
and is necessary for properly copying additional properties on custom subclasses of GraphObject.
</li>
<li>
Added properties <a>Picture.flip</a> and <a>TextBlock.flip</a>, which default to <a>GraphObject,None</a>,
can be set to <a>GraphObject,FlipHorizontal</a>, <a>GraphObject,FlipVertical</a>,
or <a>GraphObject,FlipBoth</a> to flip a Picture's or TextBlock's rendering.
</li>
<li>
Added properties <a>Shape.graduatedSkip</a> and <a>TextBlock.graduatedSkip</a>, which allow ticks/labels
along a Graduated panel
to be skipped, causing gaps. These properties take a function, and default to null meaning no ticks/labels
will be skipped.
</li>
<li>
Added predefined builders for "ToolTip" and "ContextMenu" for ease of template creation.
The definitions for these builders can be found in <a href="extensions/Buttons.js">Buttons.js</a>
</li>
<li>
Added <a>TextBlock,WrapBreakAll</a> as a value for <a>TextBlock.wrap</a>,
which allows text to break at individual characters.
</li>
<li>
Added <a>TextBlock,getBaseline</a>, <a>TextBlock,setBaseline</a>, <a>TextBlock,getUnderline</a>, <a>TextBlock,setUnderline</a>,
which give more control over the height to that lines of text and underlines are drawn.
</li>
<li>
Added <a>GraphObject.getDocumentBounds</a>, as a convenient way to avoid having to call <a>GraphObject.getDocumentPoint</a>
on all four corner points of a rectangular area.
</li>
</ul>
</li>
<li>
<b>Layouts:</b>
<ul>
<li>
Documented <a>CircularNetwork</a>, <a>ForceDirectedNetwork</a>, <a>LayeredDigraphNetwork</a>, and <a>TreeNetwork</a>.
These are the subclasses of <a>LayoutNetwork</a> for their respectively-named Layouts.
</li>
<li>
Added <a>Layout.getLayoutBounds</a> method and <a>Layout.boundsComputation</a> functional property,
