 In addition to the pseudo-arrows, \Circuitikz{} also adds a couple of ``real'' arrow tips.
-The package automatically loads the \texttt{arrows.meta} \TikZ{} library but \emph{not} the deprecated \texttt{arrows} library; in the first versions of the package it used quite a lot the \texttt{latex'} tip, which is not available anymore. To maintain the backward compatibility, the `latexslim` tip has been added, and used by default in several components. This is an old-style arrow tip, with no cusstomization possible.

 The other tip is \texttt{Jack Tap}\footnote{Added after a suggestion from \href{https://github.com/circuitikz/circuitikz/issues/806}{Anisio Rogerio Braga} on GitHub}, which is mainly used to build jack connectors (see section~\ref{sec:jacks}). This is a new-style arrow tip, and accepts the parameter \texttt{length} (default \texttt{0.3 cm}), \texttt{width} (default \texttt{0.15 cm}), and the boolean \texttt{swap}.

 \subsection{Terminal shapes}\label{sec:terminals}
 
 These are the so-called ``bipole nodes'' shapes, or poles (see section~\ref{sec:bipole-nodes}). These nodes are always filled; the ``open'' versions (starting with an \texttt{o}) are by default filled with the color specified by the key \texttt{open nodes fill} (by default \texttt{white}), but you can override locally it with the \texttt{fill} parameter.
