<h1>Release notes for Recoll 1.21.x</h1>
<h2>Caveats</h2>
<p><em>Installing over an older version</em>: 1.19 </p>
<p>1.20 and 1.21 indexes are fully compatible. Installing 1.21
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, 1.21 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 (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</h2>
<ul>
<li>1.21.1:
<ul>
<li>Force memory usage limits on external filters.</li>
<li>GUI: add Ctrl+l as a shortcut to return focus to the
search entry (compat with web browsers).</li>
<li>result list popup allows saving results from web cache
to files.</li>
<li>The web history indexer also processes non-html files
(e.g.: pdfs).</li>
</ul>
</li>
</ul>
<h2>Changes in Recoll 1.21.0</h2>
<ul>
<li>Allow saving queries to files and reloading them
later. Available both for simple and advanced queries, and
based on XML files.</li>
<li>A Bison-based query parser replaces the old regexp-based
one and allows parenthized sub-expressions and easier future
expansions.</li>
<li>The GUI gets a "close to system tray" function.</li>
<li>Avoid retrying to index previously indexed files if
nothing seems to have changed in the filters.</li>
<li>Improve indexing speed by always using vfork() for
spawning external commands.</li>
<li>The pdf filter gains the capability to run OCR (tesseract) on
image-only files. This happens automatically on image-only
pdfs if tesseract is available.</li>
<li>Improved checks about when we should try to uncompress
stuff. Will eliminate some of the most dreadful cases of
recollindex having an impact on system performance.</li>
<li>Warn if non-existent paths are listed in the configuration
file (help with typos).</li>
<li>Adjust background color for webkit-based elements (result
list and snippets window) according to desktop setup.</li>
<li>Listing the results with the KIO slave is now
performed with incremental updates. Bumped max entries to
10000.</li>
</ul>
