 * Version 1.3.8 (2021-06-15)
 
     The big news of this release is the ability to selectively draw the pins of the integrated circuit and mux-demuxes symbols.

 \subsection{Incompatible packages}
 \TikZ's own \texttt{circuit} library, which was based on \Circuitikz, (re?)defines several styles used by this library. In order to have them work together you can use the \texttt{compatibility} package option, which basically prefixes the names of all \Circuitikz\ \texttt{to[]} styles with an asterisk.

     \item Version 1.3.6 fixes several problems with the stacked labels; the most important change is that now the bracing of arguments is respected as in version 1.3.0 for the other labels. The special treatment in stacked labels (and only in stacked labels!) for the (still experimental\footnote{and, really, not advised\dots}) \texttt{siunitx} compact syntax \texttt{<...>} has been removed: it was completely buggy before, and silently ignored, now will throw an error.
     \item Version 1.3.3 fixes the direction of the arrows in tunable elements; before this version, they were more or less random, now the arrow goes from bottom left to top right. You have the option to go back to the old behavior with \texttt{\textbackslash ctikzset\{bipoles/fix tunable direction=false\}}. As a compensation for the fuss, now the arrows are configurable. To learn more, see the FAQ:~\ref{faq:tunable-arrow}.

     \item After 1.2.7 a big code reorganization (which had the collateral effect of fixing some bug) has been made; no changes should be visible, but a fallback point at 1.2.7 has been added.

 Anyway, \emph{if you know what you are doing}, you can change it with the key \texttt{poles/open fill opacity} (with \verb|\ctikzset|) or the style \texttt{open poles opacity}. Notice that you will have artifacts if you don't use the border anchors of the poles to connect wires, and you need to do that by hand.
 
+Notice that in poles, the opacity is \emph{always} selected with these keys, and it overrides the opacity of the draw commands (when not set explicitly is as if it is set to \texttt{1.0}, i.e., full opaque). This is because you normally do not want unfilled poles!
