 !! Major Improvements
 
+!!! Special Characters in Tiddler Titles
+
+In previous versions of TiddlyWiki, there were some special character sequences in tiddler titles that would break certain features. For example, a tiddler title ending in double quotes would cause the [[Table-of-Contents Macros]] to render incorrectly.
+
+As of 5.1.18, many of these problems have been fixed by refactoring the features to use the latest abilities of wikitext:
+
+* [[Table-of-Contents Macros]]
+* [[tree Macro]]
+* [[tag Macro]]
+
+Note that using certain characters in tiddler titles will still prevent some features from being used correctly. For example, two vertical bar characters are used in the double curly braces transclusion syntax to separate the tiddler title from the template title: `{{title||template}}`. However, although it would be impossible to transclude a tiddler called `title||template` using that syntax, one could still transclude it using `<$transclude tiddler="title||template"/>`.
