Todd Hooper is announcing that Prerender with version number 3.20.4 is already available to download.

What is Prerender ?

Prerender is A service that will help you pre-render JavaScript applications so they can be crawled and indexed properly by various search engine . Prerender comes to address a problematic niche in today's Web development community: getting search engine crawlers to index JS-powered apps and websites.While frameworks like Backbone.js, Ember or AngularJS have greatly simplified the process of creating truly powerful and dynamic applications using only the power of JavaScript, they have also created a whole deal of new problems for webmasters.Getting such a website or application crawled properly is almost near impossible, even if Google has tried to aid developers with plenty of tutorials and modifications to its indexing algorithm.Here is where Prerender can help developers, working on top of Node.js and pre-compiling the application or website into a static HTML page that can then be served to search engine crawlers whenever they're detected.Prerender itself is made up of two parts, the first being the aforementioned server-side service that does all the pre-rendering using PhantomJS, and second being a middleware library that can intermediate the process of sending this pre-rendered HTML to the search engine crawler instead of answering with the default code.Currently Prerender comes with middleware libraries for applications running on NginX, Apache, and Express (Node.js) and Ruby on Rails servers.At least these are the official ones. You can find additional links to some unofficial middleware for PHP, Java, and Grails in the package's README file.
