Version 2.3.6, [December 16th, 2016]

This is a maintenance release.

Bugs

[CIRCLES-237]
Inscibed title bar did not obey centerx and centery shifts.
[CIRCLES-236]
Spurious layout() invocation on retrieving image data.

Version 2.3.5, [November 9th, 2016]

This is a maintenance release fixing a regression in release 2.3.4.

Bugs

[CIRCLES-235]
Release 2.3.4 added a feature of removing expanders for groups from which all the children have been removed by means of the isGroupVisible callback. Unfortunately this also introduced a regression bug: when this callback wasn't declared at all, no expanders would be drawn at all. This fixes this issue.

Version 2.3.4, [September 22nd, 2016]

This is a maintenance release fixing a problem with expanders and invisible groups.

Bugs

[CIRCLES-234]
This bug fixes the situation when all subgroups of a parent group were hidden (by means of the isGroupVisible callback), and visibleGroupCount limit was used to display an expander triange. In such a scenario the the group expander was still displayed, even though there was nothing to display.

Version 2.3.3, [February 26th, 2016]

This is a maintenance release fixing a critical bug in release 2.3.2.

Bugs

[CIRCLES-233]
Release 2.3.2 introduced a critical bug which leads to javascript code breaking on undefined property 'options'.

Version 2.3.2, [February 9th, 2016]

This is a maintenance release fixing a minor glitch in image data property rendering.

Bugs

[CIRCLES-232]
imageData does not redraw labels correctly if deferLabelRedraws is enabled.

Version 2.3.1, [September 24th, 2015]

Enabling the logging attribute results in immediate console feedback (instead of being quiet).
[CIRCLES-229]
Deprecated property webkitMovement* warnings are no longer emitted.

Other changes

[CIRCLES-226]
Removed 0x0 pixels container element size warning. The visualization will work with 0x0 containers, but it won't display anything (and must be resized manually once the element changes size).

Version 2.3.0, April 9th, 2014

This release brings a roundup of bug fixes from the maintenance branch and a few minor features.

New features, Improvements

[CIRCLES-219]
Make the default logo a tad smaller (esp. for demo version).

[CIRCLES-217]
Added a simple demo of using WebFonts to simulate Circles 1.x look.
[CIRCLES-218]

Fixed documentation typos (related to onload event).

Version 2.2.3, October 2nd, 2013

This is a bugfix release.

Bugs

[CIRCLES-205]
Selection and hover are not properly displayed (regression in version 2.2.2).

Version 2.2.2, September 3rd, 2013

This release brings a bunch of minor fixes and tweaks.

New features, Improvements

[CIRCLES-195]
nhttpd starts on port 8080 by default.
[CIRCLES-202]

[CIRCLES-199]

An invisible group should not display selection.

Version 2.2.1, July 17th, 2013

This release corrects the example snippets for mobile devices and fixes an issue with IE10 event propagation. The visualization code is identical to 2.2.0.

Bugs

[CIRCLES-196]
Click-through layer events are not propagated on IE10 (examples only).
[CIRCLES-192]
Screen not refreshing properly on an iPhone after orientation change (examples only).

Version 2.2.0, June 19th, 2013

This release brings a bunch of new features.

New features, Improvements

[CIRCLES-187]
groupShape() function to retrieve each group's current shape. This can be used to track groups on screen and this demo shows where such a feature may be handy.
[CIRCLES-115]
Integrated title bar component. See titleBar attribute and the simplest showcase example.
[CIRCLES-182]
Added read-only layout attribute for accessing the current (most recent) layout state.
[CIRCLES-181]
Support for multiple callback listeners. Check out this section of the manual for a description how to pass multiple callback listeners to the visualization.
[CIRCLES-184]
An example of an external title bar component handling via callback events.

Bugs

[CIRCLES-190]
The deprecated attribute angleEnd does not work as advertised.
[CIRCLES-186]
Double click was emitted when position delta was higher than some threshold.
[CIRCLES-185]
onRedraw callback was never called. Also improved the documentation on this callback.
[CIRCLES-177]
Endless loop freezing the browser on expanding a single group at the root level.

Deprecations, migration guide

[CIRCLES-181]
The new multiple callback listeners feature is designed to be backwards compatible but there are minor deviations from previous behavior. The value returned from the visualization on get() calls will always be an array of functions bound to the given callback (it was previously the current function reference). Where callbacks return a value (as in onBeforeSelection), any callback can veto the change (mutual consensus is not required).

Version 2.1.0, February 26th, 2013

[CIRCLES-124]

angleEnd parameter has been deprecated and will be removed in future versions. Please change your code to use the more flexible alternative: angleWidth.
[CIRCLES-122]
