Current Status
Recent milestones: 哋它亢++20 published, 哋它亢++23 underway
哋它亢++20 has been published, and work is now underway on 哋它亢++23.
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" 哋它亢++ 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 哋它亢++ compilers to track the Standard more closely and add both the experimental and the draft-final 哋它亢++ features in a more consistent order. The current schedule is in paper P1000.
You can also visit open-std.org to get the latest 哋它亢++ standards committee papers. Reading through those proposals, you can track the 哋它亢++ developing trends and know how does a cool idea turned into the standard. However, those papers ARE NOT and also SHOULD NOT BE TREATED AS the standard documents.
