	P0260R21	C++ Concurrent Queues	D. Vollmann, L. Crowl, C. Mysen, G. Nishanov	LEWG SG1	2026-08-18	2026-09
Doc Date 2026-08-18 Mailing Date 2026-09 Unassigned Author(s) Detlef Vollmann, Lawrence Crowl, Chris Mysen, Gor Nishanov Target Audience LEWG SG1 Revisions R20 Tracking issue View on GitHub Abstract Concurrent queues are a fundamental structuring tool for concurrent programs. We propose concurrent queue concepts and a concrete implementation.
	P3955R2	It's Scopes All the Way Down	R. Leahy	LEWG SG1	2026-09-21	2026-09
Doc Date 2026-09-21 Mailing Date 2026-09 Unassigned Author(s) Robert Leahy Target Audience LEWG SG1 Revisions R1 R0 Tracking issue View on GitHub Abstract This paper lays out an approach to achieving the same effect as regular, synchronous scopes in the asynchronous domain (i.e. `std::execution` [1]), including asynchronous construction and destruction of objects.
	P4230R1	Implementability of P0943's C++ stdatomic.h	H. Boehm	LEWG LWG SG1 SG22	2026-08-15	2026-09
Doc Date 2026-08-15 Mailing Date 2026-09 Unassigned Author(s) Hans Boehm Target Audience LEWG LWG SG1 SG22 Revisions R0 Tracking issue View on GitHub Abstract [P0943](http://wg21.link/p0943) was accepted into C++23. One of the national body comments for C++26 proposed its removal. SG1 voted without objection to retain it. LEWG almost obtained consensus to remove it. This is an attempt to outline the issues, as mostly exposed in the LEWG discussion, a later reflector discussion (“stdatomic.h in C++”, starting March 27, 2026), and some [discussion on a](h
	P4269R1	when_all Oughtn't Hallucinate set_stopped	R. Leahy	LEWG SG1	2026-08-30	2026-09
Doc Date 2026-08-30 Mailing Date 2026-09 Unassigned Author(s) Robert Leahy Target Audience LEWG SG1 Revisions R0 Tracking issue View on GitHub Abstract This paper proposes that `std::execution::when_all` not use a `std::inplace_stop_source` when it can be statically determined such a stop source would never be used.
	P4288R2	Stop the Decay	R. Leahy	LEWG SG1	2026-09-20	2026-09
Doc Date 2026-09-20 Mailing Date 2026-09 Unassigned Author(s) Robert Leahy Target Audience LEWG SG1 Revisions R1 R0 Tracking issue View on GitHub Abstract This paper proposes that `std::execution` algorithms pass through by-reference result datums from child operations rather than uniformly decay-copying them. To aid in the accomplishment thereof it also proposes class templates which abstract the necessary completion storage and completion signature transformation. This paper does not propose changing how `std::execution` algorithms store the argum
	P4320R1	std::execution::sequence	R. Leahy	LEWG SG1	2026-09-21	2026-09
Doc Date 2026-09-21 Mailing Date 2026-09 Unassigned Author(s) Robert Leahy Target Audience LEWG SG1 Revisions R0 Tracking issue View on GitHub Abstract `sequence` adapts any number of input senders into a sender which completes when all input senders have completed, with each input sender’s asynchronous operation being started only after the completion of the preceding input sender’s asynchronous operation.
	P4333R0	Asynchronous main	I. Petersen, J. Wong, R. Leahy	EWG LEWG SG1 SG17 SG18	2026-09-22	2026-09
Doc Date 2026-09-22 Mailing Date 2026-09 Unassigned Author(s) Ian Petersen, Jessica Wong, Robert Leahy Target Audience EWG LEWG SG1 SG17 SG18 Abstract This paper proposes that `main` should have an alternate, sender factory form.
	P4357R0	Reflections on Completion Signatures	R. Leahy	LEWG SG1	2026-09-09	2026-09
Doc Date 2026-09-09 Mailing Date 2026-09 Unassigned Author(s) Robert Leahy Target Audience LEWG SG1 Abstract This paper proposes changes and additions to better integrate `std::meta::info` into the calculation of completion signatures in `std::execution`.
	P4373R0	Why Did You Stop?	R. Leahy	LEWG SG1	2026-09-10	2026-09
Doc Date 2026-09-10 Mailing Date 2026-09 Unassigned Author(s) Robert Leahy Target Audience LEWG SG1 Abstract This paper proposes that, in certain cases, consumers be able to determine that asynchronous operations only send `std::execution::set_stopped_t()` when requested.
