The optional argument \texttt{gsfonts} can be used to load only the symbol font from GhostScript.
Otherwise the one from URW or the system is used, which is the default.

\section{\texttt{pstricks.tex} (v. 3.03 -- 2021/08/23)}

\subsection{Arrows}
There are new arrow types and a new optional argument \texttt{tipcolor}:
\begin{LTXexample}[width=5cm]
\begin{pspicture}[showgrid](4.2,3.25)
\psline{-T>}(0,1)(4,1)
\psline[arrowscale=2]{<T-T>}(0,2)(4,2)
\psline[tipcolor=red,arrowscale=2]{<T-}(0,3)(4,3)
\end{pspicture}
\end{LTXexample}
\LPack{pstricks} defines the following "`arrows"':
\def\myline#1{\psline[linecolor=red,linewidth=0.5pt,arrowscale=1.5]{#1}(0,1ex)(1.3,1ex)}%
\def\mylineA#1{\psline[linecolor=red,linewidth=0.5pt,arrowscale=4.5]{#1}(0,1ex)(2,1ex)}%
\psset{arrowscale=1.5}
\begin{longtable}{@{} c @{\qquad} p{3cm} l @{}}%
Value & Example & Name \\[2pt]\hline
\Lnotation{-} & \myline{-} & None\\

With version 3.04 all arrow specific base code is moved to the file \LPack{pstricks-arrows}, which
is not of interest for the default user..
\subsection{Symbolfont}
Use by default the URW or system symbol font for \Lcs{psdot}. This can be changes by using
the optional argument \texttt{gsfonts}:
\begin{verbatim}
\usepackage[gsfonts]{pstricks}
\end{verbatim}
\TeX-users have to define the switch and
\begin{verbatim}
\newif\ifpstGSfonts
\pstGSfontsfalse % or true for using GS font
\input pstricks
...
\end{verbatim}
\subsection{Fillstyle \texttt{penrose}}
There was a bug if this fillstyle was used together with a line sequence.
\psset{unit=1cm}
\centering\vspace{5cm}
\pspicture[showgrid=false](-0.5\linewidth,-4.5)(0.5\linewidth,5)
\rput(0,0){\parbox{4.5cm}{%

(0.3,-1.5)(2.3,-2)(4.3,-1.5)(6.3,-2)(8,-1.5)(8,2)(-3,2)}
``One of the best new plays I have seen all year: cool, poetic,
ironic \ldots'' proclaimed \emph{The Guardian} upon the London
premiere of this extraordinary play about a Czech director and
his actress wife, confronting exile in America.

\section{\LuaLaTeX}
Currently one has to use package \LPack{auto-pst-pdf-lua} if a document with
\PSTricks-code should be run \emph{directly} with \LuaLaTeX, without using
GhostScript. This version has experimental basic support for the lua package
\LPack{luapstricks.lua}, available from \url{https://github.com/zauguin/luapstricks}.
