      <h1>Release notes for Recoll 1.23.x</h1>

      

      <h2>Caveats</h2>



      <p><em>Installing over an older version</em>: 1.19-21 </p>



      <p>Some of the input handlers were converted from shell scripts

        to Python programs, and some helper dependancies changed. For

        example, you will need to install python-libxml2 and

        python-libxslt1 in most cases (for replacing xsltproc).</p>



      <p>1.20-23 indexes are fully compatible. Installing 1.23

        over an 1.19 index is possible, but there have been small

        changes in the way compound words (e.g. email addresses) are

        indexed, so it will be best to reset the index. Still, in a

        pinch, 1.23 search can mostly use an 1.19 index. </p>



      <p>Always reset the index if you do not know by which version it

        was created (e.g.: you're not sure it's at least 1.18). The

        best method is to quit all Recoll programs and delete the

        index directory (<span class="literal">

          rm��-rf��~/.recoll/xapiandb</span>), then start <code>recoll</code>

        or <code>recollindex</code>. <br> 



        <span class="literal">recollindex -z</span> will do the same

        in most, but not all, cases. It's better to use

        the <tt>rm</tt> method, which will also ensure that no debris

        from older releases remain (e.g.: old stemming files which are

        not used any more).</p>



      <p>Case/diacritics sensitivity is off by default. It can be

        turned on <em>only</em> by editing

        recoll.conf (

        <a href="usermanual/usermanual.html#RCL.INDEXING.CONFIG.SENS">

          see the manual</a>). If you do so, you must then reset the

        index.</p>



      <h2>Minor releases at a glance</h2>



      <ul>

        <li>1.23.2:

          <ul>

            <li>Mostly released because of a couple of

              <a href="BUGS.html#b_1_23_1">bug fixes</a>.</li>

            <li>Updated rclpdf.py handler with improved metadata

              capability (will be documented shortly).</li>

          </ul>

        </li>

      </ul>



      <ul>

        <li>1.23.1:

          <ul>

            <li>Fixes for the KDE KIO slave build only.</li>

          </ul>

        </li>

      </ul>

      



      <h2>Changes in Recoll 1.23.0</h2>



      <p>Recoll 1.23 has few user-visible changes. The release was

        created mostly because some of the minor feature changes are

        critical from some niche Recoll uses (e.g.: the improved audio

        file properties indexing), and because the changes to the

        logging system were too extensive for a minor version.</p>



      <ul>

        <li>Input handler for ODF flat XML file formats.</li>

        

        <li>Configuration: some list configuration variables,

          namely <tt>skippedNames</tt>, <tt>noContentSuffixes</tt>,

          and <tt>xallexcepts</tt>, have acquired variants suffixed

          with <tt>+</tt> or <tt>-</tt> for adding or removing

          values from the default value, which is a longish list,

          which hence does not need to be copied for modification any

          more.</li> 



        <li>New <tt>nomd5types</tt> variable for listing types of

          files for which we should not compute an MD5 hash (used for

          duplicates detection). See the manual for details. The

          default list excludes the audio file types.</li>



        <li>Unicode BOM detection for text files</li>



        <li>Allow using full CSS style for term highlighting, not just

          color.</li>



        <li>Internal only: the code now uses some C++11 features

          (e.g. std::threads, std::mutex) to replace home-grown

          hacks. In consequence, a C++11 compiler is now required for

          building. Also C++ streams are used for logging.</li>



        <li><em>execm</em> input handlers now have an alternate method

          to set metadata fields, easier than HTML meta fields.</li>

      </ul>
