title: How do I upgrade boost progress?
body: <p>Version 1.71.0 of <a href="https://www.boost.org/doc/libs/1_71_0/boost/progress.hpp" rel="nofollow noreferrer">boost/progress.hpp</a> warns me:</p>
  <pre><code>include/boost/timer.hpp:21:98: note: #pragma message: This header is deprecated. 
  Use the facilities in &lt;boost/timer/timer.hpp&gt; instead.
  BOOST_HEADER_DEPRECATED( &quot;the facilities in &lt;boost/timer/timer.hpp&gt;&quot; )
  </code></pre>
  <p>But when I look in <a href="https://www.boost.org/doc/libs/1_71_0/boost/timer/timer.hpp" rel="nofollow noreferrer">boost/timer.hpp</a> there's no obvious path to upgrade, since there is no <code>boost::progress_display</code> class.</p>
  <p>In what way do the Boost folks intend for me to circumnavigate the deprecation of <code>progress.hpp</code>, other than rewriting it?</p>
