Since the current C++ Standard Library was adopted, numerous changes and improvements have been proposed, the best of which are being gathered in the C++ Library Technical Report (TR1), recently approved by the International Organization for Standardization (ISO). These new components double the size of the existing standard and are destined to be incorporated in the next official C++ Standard. Until the release of the new standard, which is still years away, C++ programmers will need this book in complement to The C++ Standard Library by Josuttis to understand the extent of C++ programming. This book serves as a reference and a tutorial on how to use each of the new features. It is divided into seven parts, each covering the new components of a particular area: utilities, function objects, type traits, numerics, containers, regular expressions, and C compatibility.
