	P2964R3	Allowing user-defined types in std::simd	Daniel Towner D. Towner , Ruslan Arutyunyan R. Arutyunyan	LEWG SG6	2026-04
Intent Proposal Mailing Date 2026-04 Post-Croydon Author(s) Daniel Towner, Ruslan Arutyunyan Target Audience LEWG SG6 Revisions R5 R4 R2 Tracking issue View on GitHub Abstract The C++ standard library includes data-parallel types in the `<simd>` header, currently restricting element types to a closed list: arithmetic types and `std::complex` specializations. This paper proposes a minimal change to the specification in which the closed list is replaced with trait-based constraints that handle all existing types while naturally extend support to enumerations, `std::byte`

	P4010R1	Add funnel shift operations to bit header	Daniel Towner D. Towner	LEWG SG6	2026-04
Intent Proposal Mailing Date 2026-04 Post-Croydon Author(s) Daniel Towner Target Audience LEWG SG6 Revisions R0 Tracking issue View on GitHub Abstract This paper proposes adding funnel shift operations to the C++ standard library. Funnel shifts concatenate two integer values, shift the concatenated result, and extract bits. This is a fundamental primitive bit operation with widespread use across many domains including cryptography, hashing, compression, and pseudo-random number generation.
	P4168R0	Fix defects in floating-point std::from_chars (LWG3081, LWG3082, LWG3456)	Jan Schultke J. Schultke	SG6	2026-04
Intent Proposal Mailing Date 2026-04 Post-Croydon Author(s) Jan Schultke Target Audience SG6 Revisions R1 Tracking issue View on GitHub Abstract This paper supersedes [[P2827R1]](https://wg21%2elink/p2827r1) and fixes [[LWG3081]](https://wg21%2elink/LWG3081), [[LWG3082]](https://wg21%2elink/LWG3082), and [[LWG3456]](https://wg21%2elink/LWG3456). It is intended as a defect report for C++17. The handling of floating-point overflow and underflow in `std::from_chars` is inconsistent; the implementations diverge from each other, and every imple
