What are the latest DeBayer/Demosaicing technics

In an effort to improve the image quality I'm getting from a camera I started digging up alternative demosaicing technics. I found out that there are allot of different algorithms but most of them are dated back to 2000. Since more than a decade has passed, I was wondering what are the latest technics around?

Algorithm or source code would be highly appreciated.

Not latest, published in 2007, the demosaicing with DFPD (Directional Filtering and a posteriori Decision) seems to give the best result. Not only it removes the artifacts at high frequency regions, it produces more crisp and natural colors than previous approaches.

This blog post compares the DFPD approach with hq bilinear interpolation and the result is quite obvious: DFPD reconstructs the image with better colors and without artifacts.

It's not the most recent work, but the results are a good improvement over classic algorithms: http://www.ipol.im/pub/algo/bcms_self_similarity_driven_demosaicking/

And you can explore the site for more algorithms and examples, with online demos and source code (open source licences). It should help you getting started.
