### Working Draft Changes

#### CWG Issues Applied

Resolutions from the following CWG issues were applied: 1287 1307 1417 1567 1575 1583 1608 1648 1424 1460 1508 1509 1514 1551 1562 1569 1570 1576 1587 1592 1593 1595 1601 1618 1649

In applying CWG1417, a word missing in the proposed wording was added: "if the function type cv-qualifiers ..." should have been "if the function type has cv-qualifiers ...".

In applying CWG1575, the word "stotate" was corrected to "storage".

#### CWG Papers Applied

Wording from the following CWG papers were applied, with editorial changes as noted:

- N3760, [[deprecated]] attribute
- N3781, Single-Quotation-Mark as a Digit Separator
  - In [lex.fcon]/1 I moved the sentence explaining that digit separators are ignored to right before its corresponding example, so that the paragraph still starts with an explanation of what a floating literal consists of.
  - In [diff.cpp11.lex] I reformatted the code example slightly.
- N3778, C++ Sized Deallocation
  - In [expr.delete]/9 I included the (not highlighted as being added) wording starting with "Otherwise" as it seemed to be intended to be added to complete the paragraph.
  - In [new.delete.array]/13 I changed the signatures to drop the nothrow_t parameter in this paragraph as this section deals with throwing array deallocation functions, not non-throwing ones.
  - In [diff.cpp11.basic] I added a reference to [basic.stc.dynamic.deallocation] for the change description. I reworded the Effect paragraph to match other change descriptions. I fixed the reference to "new.expr" to instead refer to "expr.new".

#### LWG Issues Applied

Resolutions from the following LWG issues were applied: 2141 2246 2247 2085 2087 2143 2150 2180 2194 2013 2018 2078 2097 2100 2120 2159 2275 2284 2298 2300

In addition to the above issues, I applied the suggested resolutions from NB comments GB-7, ES-15, and GB-9.

I was directed to apply the resolution to LWG issue 2235, but it had already been applied in the post-Bristol working draft.

In applying LWG2298, the second change was in fact in [meta.rel] rather than [meta.unary.prop]

In applying LWG2018, I moved the note that the function protoype is exposition only to its declaration.

In applying LWG2141, I used the `decay_t<T>` form of decay instead of `typename decay<T>::type`.

#### LWG Papers Applied

Wording from the following LWG papers were applied, with editorial changes as noted:

- N3779, User-defined Literals for std::complex
  - The title for [complex.literals] was changed from "Suffix for..." to "Suffixes for...".
  - The first paragraph's second sentence was reordered slightly to avoid an ambiguity.
- N3789, Constexpr Library Additions: functional.

As directed, I reverted the changes previously applied from the following papers:

- N3672, "A proposal to add a utility class to represent optional objects"
- N3639, "Runtime-sized arrays with automatic storage duration (revision 5)"
- N3662, "C++ Dynamic Arrays (dynarray)"

#### SG1 (Concurrency) Papers Applied

Wording from the following SG1 papers were applied:

- N3786, Prohibiting "out of thin air" results in C++14
- N3776, Wording for ~future

#### Editorial NB comments addressed

I addressed the following NB comments marked as editorial:

- US-15: Use the `_t` form of type traits.
- CH-7: [intseq.general] Clarify purpose of index_sequence.
- CH-6: [over.literal]: Mark reserved example as such.
- GB-11: [re.iter], [re.tokiter] Fix exposition-only member formatting.
