+## Next Version (Work in Progress)
+
+Changes:
+
+ * With `MD_FLAG_LATEXMATHSPANS`, LaTeX math spans (`$...$`) and LaTeX display
+   math spans (`$$...$$`) are recognized. (Note though that the HTML renderer
+   outputs them verbatim.) Thanks for the feature belong to [Tilman Roeder](
+   https://github.com/dyedgreen).

-# LaTeX
-
-With the flag `MD_FLAG_LATEXMATHSPANS`, MD4C enables extension for recognition
-of LaTeX style equation spans.
-
-An equation is is any text wrapped in tildes ($ or $$).
-
-```````````````````````````````` example
-$a+b=c$ Hello, world!
-.
-<p><equation>a+b=c</equation> Hello, world!</p>
-````````````````````````````````
-
-If a double dollar sign is used, the equation is a display equation.
-
-```````````````````````````````` example
-This is a display equation: $$\int_a^b x dx$$.
-.
-<p>This is a display equation: <equation type="display">\int_a^b x dx</equation>.</p>
-````````````````````````````````
-
-Equations may span multiple lines.
-
-```````````````````````````````` example
-$$
-\int_a^b f(x) dx
-$$
-<p><equation type="display">\int_a^b f(x) dx </equation></p>
