#Upgrading Sequence Versions

During the beta period of Sequence (versions prior to v1.0), backwards compatibility is not a priority. Some newer versions of the Sequence beta may not be compatible with existing implementations. Should you want to upgrade to the latest version, please follow the below instructions to upgrade for each subsequent release.

##Upgrading to v0.8.5 In v0.8.5, the following two lines were removed from sequence.jquery.js:

self.sequence.css({"width": "100%", "height": "100%", "position": "relative"}); //set the sequence list to 100% width/height just incase it hasn't been specified in the CSS
self.sequence.children("li").css({"width": "100%", "height": "100%", "position": "absolute", "z-index": 1}); //do the same for the frames and make them absolute

These were removed to clean up the DOM (so there's not as many inline styles making your code look messy). If they aren't already in your CSS and you'd like to update existing Sequence themes to use sequence.jquery.js v0.8.5, the following CSS should be added:

#sequence {
	position: relative;
	height: 100%; 
	width: 100%;
}

#sequence > ul > li {
	position: absolute;
	width: 100%;
	height: 100%;
	z-index: 1;
}

#sequence > ul li > * {
	position: absolute;
}

##Upgrading to v0.8.3 The following callbacks were removed:

• beforeFirstFrameAnimatesIn()
• afterFirstFrameAnimatesIn()
• beforeLastFrameAnimatesIn()
• afterLastFrameAnimatesIn()

This functionality can still be used with existing callbacks and public variables. Use this code as an example:

sequence.beforeNextFrameAnimatesIn = function() {
	if(sequence.nextFrameID == 1) {
	    //do something before the first frame animates in
	}

	if(sequence.nextFrameID == sequence.numberOfFrames) {
	    //do something before the last frame animates in
	}
}

##Upgrading to v0.8 (Required) 0.8 changed the way in which Sequence applies the animate-in and animate-out classes to elements. Prior to this version, Sequence gave each element to be animated these class names, instead, they are now given to the frame (the <li> element) instead.

• The CSS used for a Sequence theme should be modified to reflect this change. Take the following examples of how the .animate-in and .animate-out should be changed:

Existing HTML:

<div id="sequence">
	<ul>
		<li>
			<div class="title">Title</div>
		</li>
		<li>
			<img class="model" src="images/model.png" />
		</li>
	</ul>
</div>

Existing CSS to select the title and model in the above HTML:

.title.animate-in

li .model.animate-out

The above CSS selectors should be changed to the following to reflect the fact that animate-in and animate-out now apply to the frame (<li>) elements instead of the elements within frames:

.animate-in .title

li.animate-out .model

##Upgrading to v0.7.4.1 0.7.4.1 changed the default value of the preloader setting from true to false.

• If using the preloader functionality, please include preloader: true in your Sequence options, like so:

    var options = {
    	autoPlay: true,
    	preloader: true
    }
  
    var sequence = $("#sequence").sequence(options).data("sequence");
  

##Upgrading to v0.7.2 0.7.2 changed the way in which callbacks are used and renamed the paused public variable.

• paused should be changed to isPaused

• Prior to this version, callback functionality was added to Sequence options, like so:

  var options = { autoPlay: true, beforeNextFrameAnimatesIn: function() { //code to run before the next frame animates in } }

  var sequence = $("#sequence").sequence(options).data("sequence");

Callbacks are now added outside of the Sequence options, like so:

var options = {
	autoPlay: true
}

var sequence = $("#sequence").sequence(options).data("sequence");

sequence.beforeNextFrameAnimatesIn = function() {
	//code to run before the next frame animates in
}

##Upgrading to v0.6.7 0.6.7 renamed the afterPreload setting.

• afterPreload should be changed to afterLoaded

##Upgrading to v0.6.5 0.6.5 renamed the delayDuringOutInTransitions setting.

• delayDuringOutInTransitions should be changed to transitionThreshold

##Upgrading to v0.6.2 0.6.2 renamed the touchEnabled and keysNavigate settings.

• touchEnabled should be changed to swipeNavigation
• keysNavigate should be changed to keyNavigation

##Upgrading to v0.6

0.6 renamed the before/after callbacks and the current class to current-frame.

• before/after callbacks should be renamed to the following beforeNextFrameAnimatesIn, afterNextFrameAnimatesIn and beforeCurrentFrameAnimatesOut.

• Any instance of the class current, should be renamed to current-frame.
