<h2>New Papers</h2>

<ul>
  <li>V1 of the Library Fundamentals TS has been sent for publication.
  <li>N4529 is the current working draft for V2 of the Library Fundamentals TS. It replaces N4336.
  <li>N4530 is this Editor's Report.
</ul>

<p>
V1 has 3 issues applied from the Lenexa meeting, and is being sent for publication.

<p>
V2 has 5 motions applied from the Lenexa meeting.

<h2>Notable Changes to Issues and Papers as Moved</h2>

<h3>Retargeted N4371 to the Fundamentals TS</h3>

<p>
  This paper was written as changes to the main C++ standard, so
  I had to adjust headers and section numbers to make it fit into the TS.
</p>

<h3>Updated the feature testing macros</h3>
<p>
  Not all applied papers proposed feature-test macros, so I invented
  some. I also gave all new features a value of <code>201505</code>.
</p>

<h3>Rearranged the Source Locations paper a bit</h3>
<p>
  Put definitions outside the synopsis section, gave the synopsis a
  "synop" stable name, and put all creation operations together.
</p>

<h2>All Changes to V1</h2>

Date:   Sat Nov 22 23:58:53 2014 -0800

commit b3e5cdf7d39c8ded92dcf4bd4dff35308eb06771
Author: Jeffrey Yasskin &lt;jyasskin@gmail.com>
Date:   Sun Nov 23 00:02:38 2014 -0800

commit 17ad117df927a338989468288d63226c5f2cf5d5
Author: Jeffrey Yasskin &lt;jyasskin@gmail.com>

    Remove a description of a char* as a "string" in string.view.cons.

    This handles the PDTS comment FI3 editorially. I didn't include the extra
    description of an "array of charT" from string.cons because the postcondition
    table is sufficient.
