<h3>Notable changes to papers as moved</h3>
<h4>CWG motion 1, issue 2017</h4>
<p>Corrected normative wording suggesting that reaching the end of a constructor,
destructor, or function with cv-qualified <code>void</code> return type would result in
undefined behavior. These cases were not covered by the wording in the issue
because they are not functions with a <code>void</code> return type.</p>
<h4>CWG motion 12 (hexadecimal floating literals)</h4>
<p>The wording for this proposal omitted an essential update to the <em>pp-number</em>
grammar production, which is necessary to avoid a literal such as <code>0x1.0p+0</code>
being split into three tokens at the <code>+</code> character. The grammar has also been
editorially refactored to reduce duplication between hexadecimal floating
literals and hexadecimal integer literals.</p>
<h4>LWG motion 4 (parallelism TS)</h4>
<p><code>std::sequential</code>, <code>std::par</code>, and <code>std::par_vec</code> were not listed in the
synopsis of any library header. They have been added to the synopsis of
<code><execution_policy></code>, based on the clear intent of their placement within the
wording.</p>
<p>[execpol.synopsis] was renamed to [execpol.syn] for consistency with other
synopsis subclauses.</p>
<p>[algorithms.parallel.exec]: fixed incorrect claims that certain well-formed
constructs with defined (but undesirable or unspecified) behavior are an error,
or undefined, in examples.</p>
<p>[exception.list]: added missing synopsis for <code><exception_list></code> header.</p>
<p>[numerics.defns]: rephrased definition of <em>GENERALIZED_SUM</em> in terms of
<em>GENERALIZED_NONCOMMUTATIVE_SUM</em> to reduce redundancy.</p>
<p>Contrary to the editing instructions in section 25.NaN.5 (sic), parallel
overloads of <code>for_each</code> and <code>for_each_n</code> were not added to the synopsis of
<code><algorithm></code> as they would conflict with the overloads added in section
25.2.4.</p>
<h4>LWG motion 6 (lib fundamentals TS)</h4>
<p>The changes to <code>shared_ptr</code> have <strong>not</strong> been applied, as it is unclear
exactly what changes should be made. The TS provides alternative wording
for some subsections, but some of the differences are due to changes in
the TS and some are due to changes in the working paper. Replacing the
sections in the working paper with the sections from the TS would regress
some functionality, so this portion of this motion has been returned to
LWG for a more precise specification.</p>
<h4>LWG motion 11 (<code>is_{nothrow_}swappable</code>)</h4>
<p>Changed new uses of <code>is_{nothrow_}swappable<T>::value</code> to instead use
<code>is_{nothrow_}swappable_v<T></code>.</p>
<h4>LWG motion 13 (<code>clamp</code>)</h4>
<p>Note that the paper voted into, and applied to, the working draft was
<a href="http://wg21.link/p0025r0">P0025R0</a>,
not the most recent draft of this paper,
<a href="http://wg21.link/p0025r1">P0025R1</a>.
This appears to be an oversight; LWG is encouraged to prepare an issue
to apply the changes from P0025R0 to P0025R1.</p>
<h4>LWG motion 17 (non-const <code>std::string::data</code>)</h4>
<p>Fix Annex C change to correctly describe the change that was made.</p>

[defns.const.subexpr] Place defintition in alphabetical order
The defintions introduced in clauses 1.3 and 17.3 are
ordered alphabetically, other than the trailing
definition for 'constant subexpression', that I am
guessing was added at a later date. This change
simply moves it into the correctly sorted place in
the sequence.

[diff.cpp11.expr] Move removal of bool++ from C++14 compatibility annex to C++17 annex
This change was clearly introduced in C++17, at the same meeting
as removing the meaning of the register keyword. I can see no
Core issue tied to this removal being resolved as a DR against
14 or earlier.
I have confirmed that paper p0002r1 applied this to the C++17
annex, but was listed as a change in annex D rather than clause
5 - the latter change seeming the consistent editorial policy
for removed Core features, so retained.

Swap the descriptions so that `assign` is now defined in terms of `operator=`. No functional change to either is intended.

[dcl.type.cv]/6 "program behavior" vs "behavior"
[dcl.type.cv]/6 reads
> If an attempt is made to refer to an object defined with a volatile-qualified type through the use of a glvalue with
a non-volatile-qualified type, the program behavior is undefined.
This is probably meant to use the much more idiomatic phrase "the behavior is undefined". A distinction between well-definedness of the program's and the implementation's behavior would presumably be inappropriate, anyway.
