Geek joke: C++0x is in hex, so the next version can come out as late as 200f and still meet the initial target
In October 2006, the ISO committee laid out a plan to issue an approved document by 2009. Unfortunately, the plan has slipped by a year.
Latest timetable from October 2007 meeting:
- publish feature-complete draft in September 2008
- complete fine-tuning and editorial work in 2009
October 2007: decided to compromise on some of the major features planned for C++0x: advanced concurrency libraries, and garbage collection

Memory model
- define what happens when two threads access memory at the same time
- constrict what optimizations a compiler can make (to respect memory barriers)
atomic types
standard library API enhancements
- create and manage threads
- locks, mutexes, condition variables
- October 2007: decided standard will ship without more complex library functions

Concepts: define capabilities required from template parameters
- October 2007: decided to be a must for standard
rvalue semantics: support for moving objects (instead of copy-destroy)
constexpr functions: use result where a constant is needed
auto / decltype: automatic inferring of type from RHS/expression
nullptr
garbage collection
- October 2007: deferred; some blocking issues addressed
Lambda functions and closures
