Recent milestones: C++23 feature-complete, out for comment ballot
C++20 and many TSes have been published, and work is now underway on more TSes and C++23 as shown below.
Starting in 2012, the committee has transitioned to a "decoupled" model where major pieces of work can progress independently from the Standard itself and be delivered in "feature branch" TSes. Vendors can choose to implement these, and the community can gain experience with the
std::experimental version of each feature. This lets us learn and adjust each feature's design based on experience before it is cast in stone when merged into the "trunk" C++ Standard itself. In the meantime, the Standard can be delivered on a more regular cadence with smaller and more predictable batches of features. This approach also helps C++ compilers to track the Standard more closely and add both the experimental and the draft-final C++ features in a more consistent order. The current schedule is in paper P1000.
Many TSes are focusing particularly on producing new C++ standard libraries; to participate, see the instructions for how to Submit a Proposal. See the table below for current status.
Here is a summary of the currently active projects and their appointed Project Editors.
- Programming Language C++ IS: Thomas Köppe. This is the main C++ Standard project.
- Library Fundamentals TS: Thomas Köppe. A set of standard library extensions for vocabulary types and other fundamental utilities.
Concurrency TS: Michael Wong. Initially includes library support for executors and non-blocking extensions to
std::future. Additionally may include language extensions like coroutines, and additional libraries such as concurrent hash containers and latches.
