 The following new features have been included in the 3.4 release:
 
-* Use `style` attribute in tables for alignment instead of `align` for better CSS

+
+    * Small refactor of the `BACKLINK_TITLE` option; The use of `format()`
+      instead of "old" `%d` formatter allows one to specify text without the
+      need to have the number of the footnote in it (like footnotes on
+      Wikipedia for example). The modification is backward compatible so no
+      configuration change is required.
+
+    * Addition of a new option `SUPERSCRIPT_TEXT` that allows one to specify a
+      custom placeholder for the footnote itself in the text.
+      Ex: `[{}]` will give `<sup>[1]</sup>`, `({})` will give `<sup>(1)</sup>`,

-* The CodeHilite extension now supports a `pygments_formatter` option that can be set to
-    use a custom formatter class with Pygments (#1187). Additionally, the specified
-    Pygments formatter is passed an extra option `lang_str` to denote the language of
-    the code block (#1258).
-    - If set to a string like `'html'`, we get the default formatter by that name.
-    - If set to a class (or any callable), it is called with all the options to get a
-      formatter instance.
+    The formatter class is now passed an additional option, `lang_str`, to
+    denote the language of the code block (#1258). While Pygments' built-in
+    formatters will ignore the option, a custom formatter assigned to the
+    `pygments_formatter` option can make use of the `lang_str` to include the
+    code block's language in the output.
