 Changes:
 
+ * The implementation of wiki-links extension (with `MD_FLAG_WIKILINKS`) has
+   been simplified.
+
+    - A noticeable increase of MD4C's memory footprint introduced by the
+      extension implementation in 0.4.0 has been removed.
+    - The priority handling towards other inline elements have been unified.
+      (This affects an obscure case where syntax of an image was in place of
+      wiki-link destination made the wiki-link invalid. Now *all* inline spans
+      in the wiki-link destination, including the images, is suppressed.)
+    - The length limitation of 100 characters now always applies to wiki-link
+      destination.
+
  * Recognition of strike-through spans (with the flag `MD_FLAG_STRIKETHROUGH`)
    has become much stricter and, arguably, reasonable.
