+- specfile:
+  * removed tornado-configtest.patch: fixed upstream
+  * update tornado-async-deprecation.patch (partly integrated)
+
+- update to version 4.5.2:
+  * Tornado now sets the FD_CLOEXEC flag on all file descriptors it
+    creates. This prevents hanging client connections and resource
+    leaks when the tornado.autoreload module (or
+    Application(debug=True)) is used.
+
+- changes from version 4.5.1:
+  * tornado.log
+    + Improved detection of libraries for colorized logging.
+  * tornado.httputil
+    + url_concat once again treats None as equivalent to an empty
+      sequence.
+
+- changes from version 4.5.0:
+  * long changelog, see http://www.tornadoweb.org/en/stable/releases/v4.5.0.html
+    for details
