fix: allow for caps in file name suffixes #206

@schinkelg ran aground of this one and I took the opportunity to add a
test to catch this sort of thing for next time.

 Changelog
 #########
 
+* 0.4.1
+  * Fix for `#206`_ wherein the pluggable parser didn't recognise files with
+    all-caps suffixes like ``.PDF``
+
+* 0.4.0
+  * Introducing reminders.  See `#199`_ for more information, but the short
+    explanation is that you can now attach simple notes & times to documents
+    which are made available via the API.  Currently, the default API
+    (basically just the Django admin) doesn't really make use of this, but
+    `Thomas Brueggemann`_ over at `Paperless Desktop`_ has said that he would
+    like to make use of this feature in his project.
+
 * 0.3.6
   * Fix for `#200`_ (!!) where the API wasn't configured to allow updating the
     correspondent or the tags for a document.
