Ending this second week of September we’ve collected some of this week’s happenings in our weekly roundup.

A little over two weeks ago we the folks over at bbPress brought us one step closer to the release of version 2.0. At the beginning of this week another stepping stone has been announced – bbPress 2.0 RC5. We’ll hopefully get to play with the 2.0 release sometime within two weeks. The development team are pretty confident that RC5 is the last release candidate.

Jean-Baptiste over at CatswhoCode.com presented quite an interesting article on Mastering HTML5 Prefetching using the rel="prefetch" attribute inside <link> tags in the <head> of your page for pages and images that you want the user browser to prefetch; pages that users are likely to request, and since they’ve been prefetched loading times should be near to instantaneous. Prefetching is currently not supported in Safari and IE, but you can make the other 70.9% of Internet users (according to w3school’s Browser Statistics) a little more happy. The article covers HTML5 prefetching (or “prerendring” as Chrome refers to it) in WordPress, offering a ready-to-be-used code snippet that you can paste into your theme’s header file, and a very useful jQuery snippet that automatically appends prefetch code to <head>.

A new WordPress tutorial over at WPBeginner has been published which goes over some of the ins and outs of How to Create Additional Image Sizes in WordPress. The tutorial makes it a point to explain what Hard Crop, Soft Crop and Unlimited Height modes are, explains a bit on how to use custom image sizes inside the WordPress loop, and features the Simple Image Sizes plugin that makes it easy to create custom image sizes, regenerate them and add them to your settings pages.

How do you make WordPress more mobile friendly? Kevin Muldoon from WPMods explores 3 plugins in his 3 WordPress Plugins That Make Your Website More Mobile Friendly. The plugins revolve around detecting and ultimately substitute your regular WordPress theme for one that is better displayed on mobile devices. We checked out WPtap Mobile Detector, which is a neat plugin and has fingerprints for 9 different mobile devices, but, unfortunately no user-friendly way to allow for the addition of new ones.
