What Does Unicode 8.0 Mean For Chinese?
So, I think I just wrap this up in a proper answer instead of some comments with links.

Basically, there are two major changes:


9 new characters were added to the  CJK Unified Ideographs block.
A new block called 'CJK Unified Ideographs Extension E' with 5762 ideographs was added to Unicode. You can find these here (.pdf file). 


Characters from the first page of the file:


According to Wikipedia, in the early stages of the new standard version, 
CJK-E was originally intended to include another 16,000+ characters not present in CJK-C. However, in May 2007 the Republic of China (Taiwan) withdrew 6,545 personal name usage characters deemed no longer in use,in May 2013 China withdrew 6 characters, and many others were later withdrawn or moved to CJK-F (projected), so the current version includes 5,762 new characters. CJK-E including 5,762 Han characters will be new in Unicode 8.0. 

Here's a Wikipedia article that will document these, but most browsers fail to display the characters yet. 



UPDATE: Hanazono supports CJK Ext. E. Download the font from here.
