 the way you build Wt, the way you configure Wt or the Wt API and
 behaviour.
 
+<h2>Release 3.3.12 (December 14, 2018)</h2>
+<p>Wt 3.3.12 is almost entirely a bugfix release. Here are the key changes:</p>
+
+<h3>Wt::Auth::UpdatePasswordWidget</h3>
+<p>The <a href="classWt_1_1Auth_1_1UpdatePasswordWidget.html">UpdatePasswordWidget</a>,
+part of the authentication subsystem of Wt, would delete itself when done.
+This was harmless when it was inside of a <a href="classWt_1_1WDialog.html">WDialog</a>, but it's less practical when
+used elsewhere. We've changed the behavior of <tt>UpdatePasswordWidget</tt> to emit the
+<a href="classWt_1_1Auth_1_1UpdatePasswordWidget.html#ad6969b769da2620e1ddceacdd171a1e8">updated()</a> and
+<a href="classWt_1_1Auth_1_1UpdatePasswordWidget.html#ab7af05f520cbd6af0a6b28165ca4f492">canceled()</a>
+signals instead.</p>
+
+<h3>Dbo: reentrant statement use</h3>
+<p>For the longest time, the Dbo tutorial has mentioned that
+&ldquo;you need to be careful to not have two collections with the same statement busy at the same time&rdquo;.
+If you did attempt concurrent use of statements, an exception mentioned that
+&ldquo;Reentrant statement use is not yet implemented&rdquo;. Starting from
+Wt 3.3.12, you won't see that error anymore. Dbo will now
+clone the prepared statement as needed.</p>
+
+<h2>Release 3.3.11 (August 22, 2018)</h2>
+<p>This release brings with it the usual bugfixes, but also some new features:</p>
+
+<h3>WCartesianChart improvements</h3>
+
+<h4>Multiple Y axis support</h4>
+
+<p>In previous versions of Wt, it was already possible to have two separate Y axes. This release
+allows for any amount of Y axes, and extends the interactive functionality to support multiple Y axes.</p>

Enable on-demand loading when you have a lot of data and/or need the ability to zoom in very far. This will make it so that only the data for the visible X range is loaded, and will improve performance of data series with large amounts data. This becomes especially useful in combination with the ability to set a maximum zoom range, so that you can't zoom all the way out to see all data.</p>

+
+<h2>Release 3.3.10 (April 12, 2018)</h2>
+<p>This release fixes compatibility with Boost 1.66, fixes some bugs, and adds
+some functionality:</p>
+<dl>
+  <dt>WFileUpload: added display widget</dt>
+  <dd>Often, native file upload field look out of place in the rest of a web application's design.
+      A common trick is to hide the file upload field, and add another widget that forwards its click
+      signal to the file upload field. We added
+      <a href="classWt_1_1WFileUpload.html#ab95ec35db690296e848d89a71c23737a">setDisplayWidget()</a>
+      to make it easy to implement that trick.</dd>
+  <dt>WFileDropWidget: added drop indication and global drop</dt>
+  <dd>When <a href="classWt_1_1WFileDropWidget.html#a0c1400a6f7f63eec4bb1cfe30807538e">drop indication</a>
+  is enabled, a WFileDropWidget will be highlighted as soon
+  as a file being dragged enters the page. When
+  <a href="classWt_1_1WFileDropWidget.html#a051b4928cb26446de1eb3617d0f8c954">global drop</a> is enabled, then a drop
+  anywhere on the page will put the file in the WFileDropWidget.</dd>
+  <dt>SqlConnection::executeSqlStateful()</dt>
+  <dd><a href="classWt_1_1Dbo_1_1SqlConnection.html#a7ac824e554074898f10cf75b70a4a6b1">SqlConnection::executeSqlStateful()</a> allows to execute SQL that should be re-executed upon automatic reconnect. Automatic reconnect
+  is currently supported for the <a href="classWt_1_1Dbo_1_1backend_1_1Postgres.html">Postgres</a>
+  and <a href="classWt_1_1Dbo_1_1backend_1_1MySQL.html">MySQL</a> backends.</dd>
+  <dt>WTableView: exposed touch events</dt>
+  <dd>
+    We made it possible to define custom behaviour upon touch events on WTableView, by
+    adding the <a href="classWt_1_1WAbstractItemView.html#acd980e6a9eb110400f334e341f8386a4">touchStarted()</a>,
+    <a href="classWt_1_1WAbstractItemView.html#aaf371c95c294c952be0eaac5b3f56af7">touchMoved()</a>, and

+  </dd>
+</dl>
+
+<h2>Release 3.3.9 (November 21, 2017)</h2>
+<p>This release consists mostly of bug fixes and adds some new features:</p>
+<dl>
+  <dt>Microsoft SQL Server backend for Wt::Dbo (also in Wt 4.0.0)</dt>
+  <dd>We've added Microsoft SQL Server support to Wt::Dbo, making it the sixth
+   backend we support, alongside Sqlite, PostgreSQL, MySQL (and MariaDB),
+   Firebird, and Oracle (not part of the open source Wt because of licensing).
+   With this addition, Wt::Dbo now supports most commonly used relational database
+   management systems. It's based on ODBC and works with Microsoft's ODBC Driver
+   for SQL Server. With unixODBC, Linux and macOS are also supported.</dd>
+  <dt>Added the <tt>--resources-dir</tt> option to wthttp (also in Wt 4.0.0)</dt>
+  <dd>With the <tt>--resources-dir</tt> option, all requests for static resources
+  (in <tt>/resources</tt>) will fallback to this specified folder, so that you don't
+   need to copy or create a symlink to the resources folder anymore. This also means
+   that resources can be selectively overridden, just by creating a file with the same
+   name in the resources folder of your docroot.</dd>
+  <dt>Added the <tt>&lt;max-formdata-size&gt;</tt> configuration option (also in Wt 4.0.1)</dt>
+  <dd>Previously, the maximum size of form data sent by Wt in a single POST request was capped to 5 MiB.
+      In applications with a large amount of forms with a lot of data, that may not be enough,
+      so <tt>&lt;max-formdata-size&gt;</tt> can be used to adjust this independently. Note that
+      the maximum request size (and by consequence, the form data size) is still capped by
+      <tt>&lt;max-request-size&gt;</tt>.</dd>
