 <!--- CircuiTikz - Changelog --->
 The major changes among the different circuitikz versions are listed here. See <https://github.com/circuitikz/circuitikz/commits> for a full list of changes.
 
+* Version 0.9.7 (2019-12-01)
+
+    The important thing in this release is the new position of transistor's labels; see the manual for details. 
+
+    - Fix the position of transistor's text. There is an option to revert to the old behavior.
+    - Added anchors for adding circuits (like snubbers) to the flyback diodes in transistors (after a suggestion from @EdAlvesSilva on GitHub).
+
 * 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.

+Please Notice that this section uses the ``new'' position for transistors labels, enabled since version \texttt{0.9.7}. You should refer to older manuals to see how to do the same with older versios; basically the transistor's names where put with a different \verb|node{}| command.

+Also notice that this is a more ``personal'' tutorial, showing a way to draw circuits that is, in the author's opinion, highly reusable and easy to do.
 The idea is using relative coordinates and named nodes as much as possible, so that changes in the circuit are easily done by changing keys numbers of position, and crucially, each block is reusable in other diagrams.
 
 First of all, let's define a handy function to show the position of nodes:

 Transistor paths have the possibility to use the poles syntax (see section~\ref{sec:bipole-nodes}) but they have \textbf{no} voltage, current, flow, annotation options.
+Also, the positioning of the labels is very simple and is not foolproof for all rotations; if you need to control them more please name the node and position them by hand, or use the more natural node style for transistors.
 
 The \texttt{name} property is available also for bipoles; this is useful mostly for triac, potentiometer and thyristor (see~\ref{sec:othertrip}).
