ISO/IEC TR 19768:2007 specifies a series of extensions to the standard library for the programming language C++, as specified by ISO/IEC 14882, in order to build more widespread existing practice for an expanded C++ standard library. Some of the components in ISO/IEC TR 19768:2007 could be considered for standardization in a future version of C++.

The specific classes of extensions specified in ISO/IEC TR 19768:2007 are as follows:

• general utilities such as reference-counted pointers;
• functional programming;
• facilities for compile-time type queries;
• enhanced support for numerical computation;
• hash tables and other additional container classes;
• regular expression processing;
• improved capability with the programming language C, as specified by ISO/IEC 9899.
