Thanks to all those who have submitted editorial issues, to those who have provided pull requests with fixes, and to everyone who drafted motion applications. Special thanks to Jan Schultke for drafting a lot of motion applications, to Andreas Krug for ongoing careful reviews, and to Daniel Krügler for an exceptionally thorough review that spotted many mistakes in the motion applications.
The Draft International Standard that will be sent for the ISO ballot has not yet been completed, but will include the changes from N5046. As usual, since N5046 has not yet been approved in a WG21 meeting, it is instead being reviewed by an editorial review committee that was selected in Croydon, as per WG21 Poll 3. N5046 includes some, but not all of the review committee’s feedback.
All motions were applied cleanly.
Some reconciliation was needed among LWG motions (in particular starting at motion 28), but paper authors and LWG had already included relevant merging instructions in the papers.
The wording of P3980R1 from LWG Motion 29 has been reconciled with intervening changes from issues LWG 4339 and LWG 4347 from LWG Motion 2.

A large number of national body comments for the C++26 Committee Draft have been addressed in this working draft.
Most editorial national body comments were addressed before the Kona 2025 meeting, see Editor’s Report N5033 for the full list.
A few additional national body comments have since been found editorial and have now been addressed:
The following national body comments were addressed by the motions approved at the Croydon 2026 meeting:
The subclause [expr.const], formerly titled “Constant expressions”, has been renamed to “Constant evaluation” and its contents have been divided into smaller subclauses; see commit 98a668efc2ab0bea86dcf9a2d8bf583dddc35e32.
A log of editorial fixes made to the working draft since N5008 is below. This list excludes changes that do not affect the body text or only affect whitespace or typeface.

[lex.phases] Make note on the notion of file more prominent
The notion that when the standard refers to files does not
necessarily imply a file in a traditional filing system is
more fundamental than its late appearance in the middle of
phase 7 of translation. Move that note right to the top of
[lex] where we first talk of storing the program text in
source files, where is will be understood even before the
phases of translation.

[exec.get.compl.{domain,sched}] Replace "it" and long expression with "the expression".
In e82e850497facd0b9f1e65f4de75b475ddde42ed I had shortened a long
expression from the incoming paper in [exec.get.compl.domain] to just
"it". In review it was suggested that "the expression" is clearer, and
that similar wording in [exec.get.compl.sched] should use the same style.
(Overall, I think it is easier to understand that the shorter
reference refers to the same expression than to have to compare
two long expressions and determine that they are equal.)

The exception that "sndr is evaluated only once" is no longer
necessary, since P3826R5 from LWG Motion 28 removed the previous

occurrence of "sndr", it does not need saying that it is only
evaluated once.

[simd.{syn,math}] Rename parameters of new overloads of various special maths functions:

* For cyl_neumann: from "x, y" to "nu, x"

* For ellint_{1,2}: from "x, y, z" to "k, nu, phi"
The paper P3844R4 (LWG Motion 4) added those overloads with parameters
named differently from the names of the existing overloads, but the
latter names seem more appropriate.

[mdspan.sub.sub] Fix submdspan slice canonicalization
Two integration errors in the Let clause introduced by P3663R3:
- the function parameter pack is named "slices", but the Let clause
references an undefined "raw_slices"; rename the parameter to match
subextents (mdspan.sub.extents);
- src is an mdspan but canonical_slices takes an extents object;
pass src.extents() instead of src.
