<h1>Release notes for Recoll 1.22.x</h1>
<h2>Caveats</h2>
<p><em>Installing over an older version</em>: 1.19 </p>
<p>1.20-22 indexes are fully compatible. Installing 1.22
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, 1.22 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>Changes in Recoll 1.22.0</h2>
<ul>
<li>The main "feature" in recoll 1.22 is that it has
a <a href="pages/recoll-windows.html">Microsoft Windows
version</a>. This is has been tested on Windows 7 and
Windows 10, and it works mostly like the Unix version, with
the notable exceptions that it has no real-time mode (need to
start indexing by hand from the GUI, or arrange something with
the command-line recollindex.exe). Also there are a few very
Unix-y file types which are not processed on Windows, and the
indexer is single-threaded.</li>
<li>Synonyms: users can define term synonyms groups in
ordinary text files. They are used only at query times to
expand a query to synonym terms.

More details</a>.</li>
<li>Most input handlers are now compatible with
Python3. Actually the only ones which are not are kept back by
the library they use. Also most external handlers are now
persistent, and quite a few shell-script have been converted
to Python for use on Windows.</li>
<li>The build system has been converted to use the autotools in
a fairly standard way. The Windows build is based on Qt
Creator and MinGW.</li>
<li>Make dehyphenation (co-worker->coworker in addition to the
normal terms) optional, active by default.</li>
<li>For people using the Firefox web page indexer add-on: a
new tool in the GUI to list and delete entries from the Web
cache.</li>
<li>Improved index statistics in the GUI, and improved display
while the indexer is working.</li>
</ul>
