Intent Proposal Mailing Date 2026-04 Post-Croydon Author(s) Ruslan Arutyunyan, Mark Hoemmen, Alexey Kukanov, Bryce Adelstein Lelbach, Abhilash Majumder Target Audience SG1 SG9 Tracking issue View on GitHub Abstract We propose `ranges` algorithm overloads (both parallel and non-parallel) for the `<numeric>` header.

	P3832R1	Timed lock algorithms for multiple lockables	T. Lyngmo	SG1 SG18
Intent Proposal Mailing Date 2026-04 Post-Croydon Author(s) Ted Lyngmo Target Audience SG1 SG18 Revisions R3 R2 Tracking issue View on GitHub Abstract C++11 introduced `std::lock` and `std::try_lock` (and C++17 introduced `std::scoped_lock`) to simplify deadlock-free acquisition of multiple lockables. These algorithms support BasicLockable and Lockable objects, but there is currently no facility for timed acquisition of multiple TimedLockable objects.
	P3833R2	std::unique_multilock	T. Lyngmo	SG1 SG18
Intent Proposal Mailing Date 2026-04 Post-Croydon Author(s) Ted Lyngmo Target Audience SG1 SG18 Revisions R3 R1 Tracking issue View on GitHub Abstract This paper proposes `std::multi_lock`, a RAII class template that combines the functionality of `std::unique_lock` and `std::scoped_lock`. Unlike `std::scoped_lock`, which provides only basic RAII semantics, `std::multi_lock` offers the full flexibility of `std::unique_lock` (deferred locking, try-lock operations, timed locking, and ownership transfer) while supporting multiple mutexes simultaneou
	P3927R2	task_scheduler Support for Parallel Bulk Execution	E. Niebler	LEWG LWG SG1

	P3941R4	Scheduler Affinity	D. Kühl	LWG SG1
Intent Proposal Mailing Date 2026-04 Post-Croydon Author(s) Dietmar Kühl Target Audience LWG SG1 Revisions R3 R2 R1 Tracking issue View on GitHub Disposition Date 2026-03Adopted Abstract There are a few NB comments raised about the way `affine_on` works:
	P3983R1	simd object representation	D. Towner, R. Arutyunyan	LEWG LWG SG1
Intent Proposal Mailing Date 2026-04 Post-Croydon Author(s) Daniel Towner, Ruslan Arutyunyan Target Audience LEWG LWG SG1 Revisions R2 R0 Tracking issue View on GitHub Abstract The Working Draft makes `simd` types trivially copyable types, which allows `std::bit_cast` operations. However, the object representation is unspecified, making the results implementation-defined.
	P4049R0	Relaxing and extending std::copy	G. D'Angelo	LEWG SG1 SG9 SG18 SG23
Intent Proposal Mailing Date 2026-04 Post-Croydon Author(s) Giuseppe D'Angelo Target Audience LEWG SG1 SG9 SG18 SG23 Revisions R1 Tracking issue View on GitHub Abstract In this table we’re summarizing the status quo and the changes brought by the options and extensions illustrated above. The table refers to `std::copy`, but similar changes are expected for the other algorithms of the family.
	P4191R0	is_nothrow_connectable_in	R. Leahy	LEWG SG1
Intent Proposal Mailing Date 2026-04 Post-Croydon Author(s) Robert Leahy Target Audience LEWG SG1 Tracking issue View on GitHub Abstract Under the original design of `std::execution` [1] one could check whether or not `std::execution::connect` threw an exception via:
