## linkurious.js - changelog:

#### 1.5.2 (July 25, 2016)

This is mostly a bugfix release. A new global setting `clickToFocus` is added. By default, the DOM container loses the focus when the mouse leaves it. If `clickToFocus` is true, the user must click on the container to focus it. Otherwise, the container is focused when the mouse enters it. The `autofocus` setting of plugins.keyboard is removed.

**Plugins:**
- #376 Fix plugins.legend: cannot use same icon for two different legend items
- #375 Fix renderers.linkurious: requires sigma.renderers.edgeLabels
- #371 Fix plugins.filters: adjacentNodes/Edges not updated to use sigma.util.map
- #369 Click to focus
- #367 Fix renderers.glyphs: insert glyphs canvas before mouse canvas
- #356 Fix plugins.legend: uncaught TypeError: Cannot read property 'widgets' of undefined

#### 1.5.1 (March 30, 2016)

- #351 layouts.forceLink: layout pulls nodes too close together
- #285 Fix exporters.image: incomplete image export on Retina screen

#### 1.5.0 (February 27, 2016)

This release improves rendering performance by x7 and reduces memory used indexes by x2. Indexes will use ES6 Map instead of Object if possible. It also provides a new plugin to integrate geospatial visualization with Leaflet. Rendering of node border has been changed (breaking) with new settings:

- Rename `borderSize` to `nodeBorderSize`
- Rename `outerBorderColor` to `nodeOuterBorderColor`
- Add `nodeBorderColor`, `nodeOuterBorderColor`, `nodeOuterBorderSize`, `defaultNodeOuterBorderColor`
- Add `nodeHoverBorderColor`, `nodeHoverOuterBorderColor`
- Add `nodeActiveBorderSize`, `nodeActiveBorderColor`, `nodeActiveOuterBorderColor`, `nodeActiveOuterBorderSize`, `defaultNodeActiveOuterBorderColor`
