Enyo 2.0b4 Release Notes

It's been five weeks since the beta 3 release, and we're now ready to package up a bunch of new work that we've been doing.

Major updates for the fourth beta:

• new List control as part of the layout library for virtual lists with cross-platform touch scrolling support
• considerable work on optimizing enyo.Scroller for mobile browsers, especially on Android
• new sample application in the support repo: CryptoTweets, a cryptogram game showing use of web APIs via JSONP, Enyo events, and Onyx widgets
• new PhoneGap support library in extra for hooking up PhoneGap/Cordova events into the Enyo event routing system

General

• minifier scripts now check for output folder existing (thanks, Ian Beck)
• calling this.inherited(arguments) when there's no base method no longer causes an exception
• enyo.forEach and enyo.map now match the ES5 specification (thanks, Rick Waldron)
• enyo.log now works from bound methods with no arguments.callee.caller value
• enyo.bind uses native implementation when possible
• new utility methods: enyo.filter and enyo.keys

AJAX

• enyo.Ajax has new xhrFields property to set properties of the inner XMLHttpRequest object
• enyo.Ajax.xhr property now set with the the inner XMLHttpRequest object during requests
• enyo.JsonpRequest moved from extra library into enyo

DOM & Events

• enyo.Control no longer renders an orphan node when .render() is called before parent is created
• enyo.Control removed the noDom property, now uses tag: null to indicate that no HTML tag should be generated.
• onPostResize event added, fires after onResize to allow for a second round of resize processing
• Enyo-generated onMove events now include delta and direction fields
• flick gestures are now quicker
• generated event method preventNativeDefault renamed to preventDefault
• "tap" events now only generated for primary mouse button
• support methods for CSS transformations were moved from Onyx into enyo.dom
• "drag" events now have xDirection and yDirection fields

UI

• enyo.RichText now defaults allowHtml to true

CSS

• .enyo-border-box CSS class added to set box-sizing method to border-box
• .enyo-clip CSS class added to turn on overflow:hidden, used with .enyo-fit
• Enyo now uses sans serif fonts by default: 'Helvetica Neue', 'Nimbus Sans L', Arial, sans-serif

Scrolling

• scrollers on touch screens now show position thumbnails if "thumb" property set to true
• enyo.Scroller.scrollToControl now has optional alignWithTop argument
• new method enyo.Scroller.scrollToNode
• new methods enyo.Scroller.scrollToBottom & enyo.Scroller.scrollToRight
• scroller now works with mouse wheels in Firefox and Internet Explorer
• scroller now has a "touch" property used to enable touch-optimized scrolling
• onScroll event works with ScrollStrategy.
• Scroller: removed nofit setting and added maxHeight. Sometimes a scroller's height should be dynamic up to a maximum size. We now support this via an explicit maxHeight setting. The value is any valid css style for the max-height property.
