-HTML Purifier 4.10.x is a maintenance release, collecting a year
-of accumulated bug fixes.  The most critical fixes relate to
-supporting PHP 7.2 properly, and there are a few other minor
-fixes.  One thing on the feature front: relative CSS length
-specifiers are now supported.  Additionally, we have officially
-dropped support for PHP 5.3; while we have not purposely broken
-HTML Purifier for this version, we are no longer testing for it.
+HTML Purifier 4.11.x is a maintenance release, collecting a year
+and a half of accumulated bug fixes.  Most notable fixes are
+compatibility with PHP 7.3, and case-sensitive matching for
+the SafeScripting whitelist.  There are a number small feature
+enhancements, including an expanded supported color list,
+initial and inherit support for {min-,max-,}{width,height}
+and multidimensional array support for purifyArray.
