It's actually not that new, but the very old and deprecated non-ANSI-standard 
stuff was removed from the libs. If you coded standard-conform before, the 
changes are very little ( in my code I only have to add a lot of "std::")

The ANSI C++ standard is active since 1998, so today all C++ book that are out 
there in the book stores (should) cover only the standard. The best known is 
probably Mr. Stroustroup's book.
If you are very good at the old C++ style, and want to learn about the 
reasoning of the ANSI comittee's changes, Mr. Kalev's book "ANSI/ISO C++" is 
very informative.

Greetings,
