  * The I18n filter was not replacing the original attributes with the
    translation, but instead adding a second attribute with the same name.
  * `TextTemplate` can now handle unicode source (ticket #125).
+ * A `<?python ?>` processing instruction containing trailing whitespace no
+   longer causes a syntax error (ticket #127).
