Special thanks to Casey Carter and Tim Song for supplying the LaTeX sources for P0896R4 (LWG motion 25, 208 pages of wording changes) and P1148R0 (LWG motion 12, 55 pages of wording changes), respectively, and to Tony Van Eerd for supplying a pull request for P1085R2 (LWG motion 23).
Thanks to all those who have submitted editorial issues and to those who have provided pull requests with fixes.

Rebased char8_t wording on the revised description of fundamental types
introduced by CWG motion 10. The description of unsigned char as the
underlying type of char8_t now renders unnecessary some of the other
wording in CWG motion 11; such wording has consequently not been applied.
After consulting with CWG, added the missing definition for "usable in constant expressions" as applied to objects and references.
Removed now-unused grammar production default-template-argument.
CWG motion 4 adds new uses of the grammar production qualified-concept-name that CWG motion 15 removes. These have been updated to instead refer to the new production type-constraint, and the normative wording of CWG motion 4 has been rewritten to use the new term "immediately-declared constraint", both of which were introduced by CWG motion 15.
Change 10 included an editing instruction to make matching changes elsewhere in the draft. There does not appear to be any "elsewhere" to make said changes. This editing instruction was ignored.
The specification of bind_front was simplified by replacing DECAY_UNWRAP
a use of the new unwrap_ref_decay_t alias template introduced by LWG motion 13.
The wording paper contained an unmarked modification of [std.iterator.tags], replacing "the most specific category tag" with "a category tag". After consulting with the paper authors, the change was intentional, and the corresponding edit has been applied despite not being marked up.
CWG motion 4 removes a grammar production from requires-clauses, but LWG motion 25 adds new uses of said grammar production. Those uses are all of the form
requires {
{ expr } -> Same<T>&;
}
After consultation with LWG, these uses have been rewritten as
requires {
{ expr } -> Same<T&>;
}
which is believed to both correctly reflect the intent and not change the meaning in practice of any of the uses introduced by LWG motion 25.
Additionally, CWG motion 4 contains an instruction to replace all constructs of the form
requires {
E; requires Concept<decltype((E)), Args>;
}
with the simpler (but now equivalent)
requires {
{ E } -> Concept<Args>;
}
throughout [concepts]. However, LWG motion 25 adds many more instances of the former pattern throughout several other clauses. All such instances throughout the working draft have been replaced.
A feature test macro name __cpp_lib_bind_front was recommended by the paper,
but no wording changes were included to add said feature test macro to the
working draft's table of feature test macros. The macro has been added to
the table anyway.
Several section labels introduced by the motions papers have been modified to match our style guide. In addition to the section labels affected by the above motions, the following changes have been made:
[string.op+=] has been renamed to [string.op.append].
[string.op+] has been renamed to [string.op.plus].
[re.regex.nmswap] was the only subclause in its parent [re.regex.nonmemb]. The former heading has been removed, leaving the old content directly in [re.regex.nonmemb].
[istream::sentry], [ostream::sentry], [ios::failure], [ios::fmtflatgs], [ios::iostate], [ios::openmode], [ios::seekdir], and [ios::Init] have been renamed, replacing the "::" with a "." and converting "Init" to lowercase.
See the appendix "Cross-references from ISO C++ 2017" in the working draft for a full list of sectoin label changes since C++17.
A log of editorial fixes made to the working draft since N4778 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.

[conv.lval] Improve a bit more the note about std::nullptr_t case

[conv.lval] Improve the note about std::nullptr_t case
The meaning of "fetched from memory" is vague, and the two uses of term
"access" [defns.access] are inappropreate here because
- it causes undefined behavior to access an inactive member of a
union, based on the rule of out-of-lifetime object [basic.life]:
> The program has undefined behavior if:
> - the glvalue is used to access the object, or
- it implies reading the referenced object of std::nullptr_t,
which is defined to be a side effect for volatile-qualified case.
[intro.execution]
> Reading an object designated by a volatile glvalue, ... are all
> side effects, ...
