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.
There have not been any motions from WG21 since the last working draft. This revision incorporates the final changes requested by the editorial review committee in preparation of the Draft International Standard (DIS) ballot, as well as other editorial changes. (Most of the feedback from the editorial review committee had already been incorporated into N5046.)
The value of the macro __cplusplus has been updated to 202603L.
A log of editorial fixes made to the working draft since N5046 is below. This list excludes changes that do not affect the body text or only affect whitespace or typeface. For a complete list including such changes (or for the actual deltas applied by these changes), consult the draft sources on GitHub.

[obj.lifetime] Reinstate phrasing "aggregate type".
This wording is in the approved paper P3726R2 from CWG Motion 9,
but was changed editorially to just "aggregate" under the assumption
that "aggregate type" is not a defined term. However, this seems
misguided; we use both the terms "aggregate type" and "class type",
even though the defined terms are just "aggregate" and "class".
It seems generally to improve clarity to refer to a "type", and here
in particular as we are talking about an "implicit-lifetime type".
Addresses editorial review committee feedback.

[time] Cleanup exposition-only names
Editorial notes:
* Apply `\exposid` to all exposition-only members in [time].
* For _`local-time-format-t`_ and _`STATICALLY-WIDEN`_, change uses of
`\placeholder` to `\exposid`.
* Rename some members of `hh_mm_ss`, `zoned_time`, and
_`local-time-format-t`_ in the style of either _`name_`_ or
_`kebab-case`_.
