WordPress 3.5 became available in the repository yesterday: http://wordpress.org/news/2012/12/elvin/ – As of today, all customers of aronprins.com have been upgraded to the latest install.
A quote from Matt Mullenweg:
It’s the most wonderful time of the year: a new WordPress release is available and chock-full of goodies to delight bloggers and developers alike. We’re calling this one “Elvin” in honor of drummer Elvin Jones, who played with John Coltrane in addition to many others.
If you’ve been around WordPress a while, the most dramatic new change you’ll notice is a completely re-imagined flow for uploading photos and creating galleries. Media has long been a friction point and we’ve listened hard and given a lot of thought into crafting this new system. 3.5 includes a new default theme, Twenty Twelve, which has a very clean mobile-first responsive design and works fantastic as a base for a CMS site. Finally we’ve spent a lot of time refreshing the styles of the dashboard, updating everything to be Retina-ready with beautiful high resolution graphics, a new color picker, and streamlining a couple of fewer-used sections of the admin.
