+%--------------------------------------------------------------------------------------
+\section{\texttt{pstricks.sty} -- \texttt{pstricks-pdf.sty}}
+%--------------------------------------------------------------------------------------
+
+There is now a new optional argument for the package: \Loption{ckeckengine}, which will
+be used in later versions. 
+ 
+%--------------------------------------------------------------------------------------
+\section{\texttt{pstricks-tex.tex}}
+%--------------------------------------------------------------------------------------
+This package collects all additional latex macros which must be definied
+when running PSTricks with tex.  They all moved from the base \texttt{pstricks.tex} into
+this new file.
+
+
+%--------------------------------------------------------------------------------------
+\section{\texttt{pstricks.tex} (v. 2.89 -- 2018/12/16)}
+%--------------------------------------------------------------------------------------
+
+Use the \Lcs{long} definition for \Lcs{@fornoop} to be compatible to the latest
+changes in \LaTeX.
+
+In old versions the macro \Lcs{rput} can't be used with the key-value setting. The latest version
+of \Lfile{pstricks.tex} defines a modified \Lcs{rput} which ckecks first if a following
+optional argument has the old behaviour, eg \Lcs{rput}\texttt{[lb]\{...\}} or 
+a key/value setting like \Lcs{rput}\texttt{[ref=lb,rot=...](...)}. However, there should be no
+change in the output and, of course, it makes no sense to mix the old and new setting in \emph{one}
+\Lcs{rput} macro. The setting refers only to the optional arguments which are valid for \Lcs{rput}:
+
+\begin{LTXexample}[width=6cm]
+\begin{pspicture}[showgrid](6,5)
+\rput[ref=rt](3,2){%
+  \psframe[linecolor=red](3,3)}
+\rput[lb](0,0){\psframe(3,3)}
+\rput{45}(3,0.5){\psframe(3,3)}
+\end{pspicture}
+\end{LTXexample}
+
+\subsection{PostScript Fonts}
+This version of PSTricks uses the Ghostscript fonts from URW instead of the
+original base 14 fonts of PostScript. For example: instead of Helvetica we use
+NimbusSanL-Regu. The URW fonts are always embedded in the created ps or pdf output.
+This is not the default for the PostScript fonts. You change this setting with the optional
+argument to \LPack{pstricks.sty}.
+
+
+\subsection{Error message}
+
+Using PSTricks with \Lprog{pdflatex} will work only when using package
+\LPack{auto-pst-pdf} and running the \TeX-file with
+
+\begin{verbatim}
+pdflatex -shell-escape <file>
+\end{verbatim}
+
+otherwise you'll get an error message which was misleading in the past:
+
+\begin{verbatim}
+[...]
+! Undefined control sequence.
+<recently read> \c@lor@to@ps 
+\end{verbatim}
+
+This changes now to 
+
+
+\begin{verbatim}
+[...]
+! Undefined control sequence.
+\c@lor@to@ps ->\PSTricks 
+                         _Not_Configured_For_This_Format
+\end{verbatim}
+
+\subsection{Random colors}
+There are now four predefined random ''colors``:
+
+\begin{verbatim}
+  \definecolor[ps]{randomgray}{gray}{Rand}%
+  \definecolor[ps]{randomrgb}{rgb}{Rand Rand Rand}%
+  \definecolor[ps]{randomcmyk}{cmyk}{Rand Rand Rand Rand}%
+  \definecolor[ps]{randomhsb}{hsb}{Rand Rand Rand}%
+\end{verbatim}
+
+\begin{LTXexample}[pos=t]
+\begin{pspicture}(10,5)
+\multido{\rA=0.0+0.1}{50}{\psline[linecolor=randomgray,linewidth=1mm](0,\rA)(10,\rA)}
+\end{pspicture}
+\end{LTXexample}
+
+\begin{LTXexample}[pos=t]
+\begin{pspicture}(10,5)
+\multido{\rA=0.0+0.1}{50}{\psline[linecolor=randomrgb,linewidth=1mm](0,\rA)(10,\rA)}
+\end{pspicture}
+\end{LTXexample}
+
+
+\begin{LTXexample}[pos=t]
+\begin{pspicture}(10,5)
+\multido{\rA=0.0+0.1}{50}{\psline[linecolor=randomcmyk,linewidth=1mm](0,\rA)(10,\rA)}
+\end{pspicture}
+\end{LTXexample}
+
+
+\begin{LTXexample}[pos=t]
+\begin{pspicture}(10,5)
+\multido{\rA=0.0+0.1}{50}{\psline[linecolor=randomhsb,linewidth=1mm](0,\rA)(10,\rA)}
+\end{pspicture}
+\end{LTXexample}
+
+
+The random counter can be initialized with \verb|\pstVerb{rrand srand}|.
+
+
+\subsection{Optional argument \texttt{xetex}}
+The output driver \Lprog{xdvipdfmx} for using \XeTeX\  or  \XeLaTeX\ is not fully
+compatible to \Lprog{dvips}. Especially some node operations will not work. If the
+\LaTeX\  package detects a programm run with \XeLaTeX\ it automatically loads the file
+\Lfile{pstricks-xetex.def} which defines some macros with a new name to keep the existing
+ones. By now there is only
+\Lcs{NCput}, which is the same as \Lcs{ncput}, but works with \XeLaTeX.
+
+If someone wants to use these macros though he/she runs not \XeLaTeX\ then these macros are
+available too by using the optional argument \Loption{xetex}:
+
+\begin{verbatim}
+\usepackage[xetex]{pstricks}
+\end{verbatim}
+
+
+
+
+

+\section{\texttt{pstricks.pro}}
+%--------------------------------------------------------------------------------------
+
+A full circle has by default an angle of 360 degrees. 
+Setting the circle with \Lcs{degrees}\Largs{17} to another value doesn't work for the 
+PostScript function \texttt{PtoC} (Polat to Cartesian -- $(r,\phi)\rightarrow (x,y)$).
+Now there is a \texttt{PtoCrel} for the new definition 
+which now takes
+the setting of \Lcs{pst@angleunit}  into account.
+
+\bigskip
+\begin{LTXexample}[pos=t]
+\degrees[16]
+\begin{pspicture}[showgrid](-2,-2)(2,2)
+\psline[linecolor=blue](!1.8 2 PtoCrel)%  45 degrees
+\end{pspicture}
+\end{LTXexample}
+
+The command \Lcs{framed} was build by clockwise line sequence. Now it is the
+other way round to get the same  behaviour as for all other commands
+with closed lines.
+
+
+There are some new PS functions
+
+\begin{verbatim}
+/AnytoDeg { pst@angleunit } def 
+/DegtoAny { 1 pst@angleunit div} def
+/AnytoRad { AnytoDeg DegtoRad } def 
+/RadtoAny { RadtoDeg DegtoAny } def
+\end{verbatim}
+
+See \LPack{pst-node} documentation for an example.
