After upgrading the markup formatter plugin from 1.8 to 2.0 HTML code in system message, job description, build description and testresult description fields loses attributes like for example class attributes.
We use these HTML descriptions a lot and also use the Simple Theme Plugin to style them. Without CSS classes this is not really possible.
Now, to style my job descriptions I need to use the Simple Theme plugin, but since I can't add *class* to a *div* anymore, I need to use selectors like
*div#description>div>div:nth-child(2)*
to style them. Or, I suppose, I can switch to using *style=""* since all my job descriptions are generated with Job DSL anyway.
