Created attachment 165802 [details]
(see end of description for details) screenshots, source of different versions

After upgrading vom v1.6.3 to v1.7.1 the content and layout of out doxygen-projects changed heavily. No changes on the interpreted source code (c#)
has been made but the output is very ugly now.

(1)
Having a piece of documentation with a couple of lines starting with triple slashes (///) was handled correct in 1.6.3. The triple slashes were omitted
in the formatted output.
Now (v1.7.1) these triple slashes appear inside the formatted output (see attachements, each for 163 and 171 repectively ... together with some fragments of the source code).

(2)
Maybe connected to that problem is the interpretation of html-tags included.
The lines
/// <ul>
/// <it>an item description
/// </ul>
are not working anymore and we get errors according 'lonely <li>-items'.
Other multiline-html-formattings behave similar (badly).

? Maybe there is another new option which switches back
  to the fine results of 163 ?.
? Maybe I have to improve the html-formattings and 
  everything will go right afterwards ?

referring attachments ...
(a) There are t_w_o  examples
     - codeFlow_mark (a method)
     - codeFlow_nodeFormStandards (an informational piece with dot-graphs)
(b) Both are presented 
     - as extracts from the source code
     - als screenshots (*.png) for version 1.6.3 and 1.7.1 respectively
(c) I have to commit that the screenshots derive from different OS
    (WinXPx86 and Win7x64 respectively) but before upgrading on doxygen 1.7.1
    on Win7x64 everything was nice as on WinXPx86.
