+<ul>
+  <li>

+    this fixes issues caused by the <tt>id_</tt> being removed before other things that depend on it,
+    like the <tt>jsScrollVisibilityChanged_</tt> signal. Fixes
+    <a href="https://redmine.webtoolkit.eu/issues/7508" target="_blank">issue #7508</a>.
+  </li>
+  <li>
+    Fixed join information not being copied over when copying

+  </li>
+  <li>
+    MinGW fixes: Direct2D/DirectWrite were disabled and are now enabled
+    by default. Libraries were changed to lowercase for cross-compiling
+    from Linux. Windows is case-insensitive, and MinGW libraries on Linux
+    are lowercase.
+    Fixes <a href="https://redmine.webtoolkit.eu/issues/7505" target="_blank">issue #7505</a>.
