+  Version 0.9.6 (2019-11-09)
+
+  The highlights of this release are the new multiple terminals BJTs and
+  several stylistic addition and fixes; if you like to pixel-peep, you
+  will like the fixed transistors arrows. Additionally, the transforms
+  are much more configurable now, the ``pmos'' and ``nmos'' elements
+  have grown an optional bulk connection, and you can use the ``flow''
+  arrows outside of a path.
+
+  Several small and less small bugs have been fixed.
+
+  \begin{itemize}
+  \tightlist
+  \item
+    Added multi-collectors and multi-emitter bipolar transistors
+  \item
+    Added the possibility to style each one of the two coils in a
+    transformer independently
+  \item
+    Added bulk connection to normal MOSFETs and the respective anchors
+  \item
+    Added ``text'' anchor to the flow arrows, to use them alone in a
+    consistent way
+  \item
+    Fixed flow, voltage, and current arrow positioning when ``auto'' is
+    active on the path
+  \item
+    Fixed transistors arrows overshooting the connection point, added a
+    couple of anchors
+  \item
+    Fixed a spelling error on op-amp key ``noinv input down''
+  \item
+    Fixed a problem with ``quadpoles style=inner'' and ``transformer
+    core'' having the core lines running too near
+  \end{itemize}

   Version 0.9.5 (2019-10-12)
 
   This release basically add features to better control labels, voltages

+In addition to the standard BJTs transistors, since version~\texttt{0.9.6} the \texttt{bjtnpn} and \texttt{bjtpnp} are also available; these are devices where you can have more collectors and emitters (on the other hand, they have no \texttt{photo} nor \texttt{bodydiode} options --- they are silently ignored).
+
+Basically they are the same as the normal \texttt{npn} and \texttt{pnp}, and they (by default) have similar sizes; the options \texttt{collectors} and \texttt{emitters} will change the number of the relative terminals. The base terminal is connected midway from the collector and the emitter, \emph{not} on the center of the base; a \texttt{cbase} anchor is available if you prefer to use it. The label of the component (the text) is set on the right side, vertically centered around the base terminal.

+Finally, all transistors, except the multi-terminal \texttt{bjtnpn} and \texttt{bjtpnp}, (since \texttt{0.9.6}) have internal nodes on the terminal corners, called \texttt{inner up}  and \texttt{inner down}; you do not normally need them, but they are here for special applications:
