<h3>Fixes<a class="headerlink" href="#fixes" title="Permalink to this headline">¶</a></h3>
<ul class="simple">
<li><p>Fixed a bug that there is possible that index is corrupt when Groonga executes many additions, delete, and update information in it.</p>
<ul>
<li><p>This bug occurs when we only execute many delete information from index.
However, it doesn’t occur when we only execute many additions information into index.</p></li>
<li><p>We can repair the index that is corrupt by this bug using reconstruction of it.</p></li>
<li><p>This bug doesn’t detect unless we reference the broken index.
Therefore, the index in our indexes may has already broken.</p></li>
<li><p>We can use [<a class="reference internal" href="reference/commands/index_column_diff.html"><span class="doc">index_column_diff</span></a>] command to confirm whether the index has already been broken or not.</p></li>

<ul>
<li><p>Improved performance when we specified <code class="docutils literal notranslate"><span class="pre">-1</span></code> to <code class="docutils literal notranslate"><span class="pre">limit</span></code>.</p></li>
<li><p>[<a class="reference internal" href="reference/commands/reference_acquire.html"><span class="doc">reference_acquire</span></a>] Added a new option <code class="docutils literal notranslate"><span class="pre">--auto_release_count</span></code>.</p>
<ul>
<li><p>Groonga reduces a reference count automatically when a request reaching the number of value that is specified in <code class="docutils literal notranslate"><span class="pre">--auto_release_count</span></code>.</p></li>
<li><p>For example, the acquired reference of <code class="docutils literal notranslate"><span class="pre">Users</span></code> is released automatically after the second <code class="docutils literal notranslate"><span class="pre">status</span></code> is processed as below.</p>
<div class="highlight-none notranslate"><div class="highlight"><pre><span></span>reference_acquire --target_name Users --auto_release_count 2
status # Users is still referred.
status # Users' reference is released after this command is processed.
</pre></div>
</div>
</li>
<li><p>We can prevent a leak of the release of acquired reference by this option.</p></li>
</ul>
</li>
<li><p>Modify behavior when Groonga evaluated empty <code class="docutils literal notranslate"><span class="pre">vector</span></code> and <code class="docutils literal notranslate"><span class="pre">uvector</span></code>.</p>
<ul class="simple">

</ul>
</li>
</ul>
</li>
<li><p>[<a class="reference internal" href="reference/normalizers.html"><span class="doc">Normalizers</span></a>] Added a new Normalizer <code class="docutils literal notranslate"><span class="pre">NormalizerNFKC130</span></code> based on Unicode NFKC (Normalization Form Compatibility Composition) for Unicode 13.0.</p></li>

<li><p>From this release, the targets of <code class="docutils literal notranslate"><span class="pre">--recursive</span> <span class="pre">dependent</span></code> are only the target table’s key and the index column that is set to data column.</p></li>
</ul>
</li>
<li><p>[<a class="reference internal" href="reference/commands/select.html"><span class="doc">select</span></a>] Add support for ordered near phrase search.</p>
<ul>
<li><p>Until now, the near phrase search have only looked for records that the distance of between specified phrases near.</p></li>

<h3>Improvements<a class="headerlink" href="#id14" title="Permalink to this headline">¶</a></h3>
<ul class="simple">
<li><p>[<a class="reference internal" href="reference/commands/logical_range_filter.html"><span class="doc">logical_range_filter</span></a>] Improved search plan for large data.</p>
<ul>
<li><p>Normally, <code class="docutils literal notranslate"><span class="pre">logical_range_filter</span></code> is faster than <code class="docutils literal notranslate"><span class="pre">logical_select</span></code>.
However, it had been slower than <code class="docutils literal notranslate"><span class="pre">logical_select</span></code> in the below case.</p>
<ul>
<li><p>If Groonga can’t get the number of required records easily, it has the feature that switches index search from sequential search. (Normally, <code class="docutils literal notranslate"><span class="pre">logical_range_filter</span></code> uses a sequential search when records of search target are many.)</p></li>
<li><p>The search process for it is almost the same as <code class="docutils literal notranslate"><span class="pre">logical_select</span></code> if the above switching occurred.
So, <code class="docutils literal notranslate"><span class="pre">logical_range_filter</span></code> is severalfold slower than <code class="docutils literal notranslate"><span class="pre">logical_select</span></code> in the above case if the search target is large data.
Because <code class="docutils literal notranslate"><span class="pre">logical_range_filter</span></code> executes sort after the search.</p></li>
</ul>
</li>
<li><p>If we search for large data, Groonga easily use sequential search than until now since this release.</p></li>
<li><p>Therefore, <code class="docutils literal notranslate"><span class="pre">logical_range_filter</span></code> will improve performance. Because the case of the search process almost the same as <code class="docutils literal notranslate"><span class="pre">logical_select</span></code> decreases.</p></li>
</ul>
</li>
<li><p>[httpd] Updated bundled nginx to 1.19.1.</p></li>
<li><p>Modify how to install into Debian GNU/Linux.</p>
<ul>
<li><p>We modify to use <code class="docutils literal notranslate"><span class="pre">groonga-apt-source</span></code> instead of <code class="docutils literal notranslate"><span class="pre">groonga-archive-keyring</span></code>. Because the <code class="docutils literal notranslate"><span class="pre">lintian</span></code> command recommends using <code class="docutils literal notranslate"><span class="pre">apt-source</span></code> if a package that it puts files under the <code class="docutils literal notranslate"><span class="pre">/etc/apt/sources.lists.d/</span></code>.</p>
<ul>
<li><p>The <code class="docutils literal notranslate"><span class="pre">lintian</span></code> command is the command which checks for many common packaging errors.</p></li>

<li><p>Added support for recycling the IDs of records that are deleted when an array without value space delete.[GitHub#mroonga/mroonga#327][Reported by gaeeyo]</p>
<ul>
<li><p>If an array that doesn’t have value space is deleted, deleted IDs are never recycled.</p></li>
<li><p>Groonga had used large storage space by large ID. Because it uses large storage space by itself.</p>
<ul>
<li><p>For example, large ID is caused after many adds and deletes like Mroonga’s <code class="docutils literal notranslate"><span class="pre">mroonga_operations</span></code></p></li>

<ul>
<li><p>It calls <code class="docutils literal notranslate"><span class="pre">grn_obj_unlink()</span></code> only on the reference count mode. It doesn’t do anything except when the reference count mode.</p></li>

<h3>Fixes<a class="headerlink" href="#id123" title="Permalink to this headline">¶</a></h3>
<ul class="simple">
<li><p>Fixed a bug that nonexistent sort keys for <code class="docutils literal notranslate"><span class="pre">drilldowns[LABEL]</span></code> or
<code class="docutils literal notranslate"><span class="pre">slices[LABEL]</span></code> causes invalid JSON parse error. [Patch by Naoya
Murakami] [GitHub#627]</p></li>
<li><p>Fixed a bug that access to nonexistent sub records for group causes
a crash. For example, This bug affects the case when you use
<code class="docutils literal notranslate"><span class="pre">drilldowns[LABEL].sort_keys</span> <span class="pre">_sum</span></code> without specifying
<code class="docutils literal notranslate"><span class="pre">calc_types</span></code>. [Patch by Naoya Murakami] [GitHub#625]</p></li>
<li><p>Fixed a crash bug when tokenizer has an error. It’s caused when
tokenizer and token filter are registered and tokenizer has an
error.</p></li>
<li><p>[<a class="reference internal" href="reference/window_functions/window_record_number.html"><span class="doc">window_record_number</span></a>] Fixed a
