### New and noteworthy
#### Changes in how tab characters are handled
In the past, tab characters in source files has been handled differently in different languages by PMD.
For instance in Java, tab characters had a width of 8 columns, while C# used only 1 column. Visualforce instead
used 4 columns.
This has been unified now so that tab characters are consistently now always 1 column wide.
This however might be a **incompatible** change, if you're using the properties "BeginColumn" or "EndColumn"
additionally to "BeginLine" and "EndLine" of a Token/AST node in order to highlight
where a rule violation occurred in the source file. If you have logic there that deals with tab characters,
you most likely can remove this logic now, since tab characters are now just "normal" characters
in terms of string processing.
