 Here, we will provide a list of incompabilitys between different version of circuitikz. We will try to hold this list short, but sometimes it is easier to break with old syntax than including a lot of switches and compatibility layers.
 You can check the used version at your local installation using the macro \verb!\pgfcircversion{}!.
 \begin{itemize}
-    \item Due to a bug fix in \TikZ{} that revealed a problem in \Circuitikz, you \textbf{must} upgrade to v1.2.7 or newer if you use a \TikZ{} 3.1.8 or 3.1.8a (the change in \TikZ{} has been reverted later).
+    \item After 1.2.7 a big code reorganization (which by the way fixed some bug) has been made; no changes should be visible, but a fallback point at 1.2.7 has been added.

     \item After v1.2.1: \textbf{Important:} the routine that implement the \texttt{to[...]} component positioning has been rewritten. That should enhance the line joins in path, and it's safer, but it can potentially change behavior.
