5 NEW FEATURES
==============
-Option `pdfa' added
--------`----'------
+Experimental option `ocgcolorlinks'

+ This new experimental option `ocgcolorlinks' uses Optional Content
+ Groups, a feature introduced in PDF 1.5.
+ * The option must be given for package loading:
+ \usepackage[ocgcolorlinks]{hyperref}
+ * Main disadvantage: Links cannot be broken across lines.
+ PDF reference 1.7: 4.10.2 "Making Graphical Content Optional":
+ Graphics state operations, such as setting the color, ...,
+ are still applied.
+ Therefore the link text is put in a box and set twice, with and
+ without color.
+ * The feature can be switched of by \hypersetup{ocgcolorlinks=false}
+ inside the document.
+ * Supported drivers: pdftex, dvipdfm
+ * The PDF version should be at least 1.5. It is automatically
+ set for pdfTeX. Users of dvipdfmx set the version on the command
+ line: dvipdfmx -V 5
