 <!--- 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 1.3.4 (2021-04-20)
+
+    New things, like configurable modifier thickness, ferroelectric devices, and several transistor tweaks. Importantly, a bug that hindered compatibility with the internal Ti*k*Z `circuits` library (introduced in 1.3.3) has been fixed.
+
+    - Added separate configuration for the line thickness of resistors, capacitors, and inductors modifiers
+    - Added ferroelectric capacitors and ferroelectric gate MOS/FETs (suggested by Mayeul Cantan, https://github.com/circuitikz/circuitikz/issues/515)
+    - Added an option to fill the gate gap in MOSes, FETs and IGBTs with a color
+    - Added a "centergap" anchor for transistors
+    - Added the option "nogate" to the `hemt` symbol
+    - Fixed a bug in thermistors not respecting their class line thickness
+    - Fixes in the manual (copy and paste of snippets without numbers, correct old usage of `siunitx`, factor out repetitions in the preamble; thanks to Ulrike Fischer:
+    https://tex.stackexchange.com/a/57160/38080)
+    - Fixed a bug introduced in 1.3.3 that would reduce compatibility with the `circuits` internal library; reported by JetherReis (https://github.com/circuitikz/circuitikz/issues/519)
+
 * Version 1.3.3 (2021-04-04)
 
     Several usability additions in this version, and one small fix that could
     change the look of your circuit (without affecting correctness). Some of the
     arrow shapes are now configurable.
 
+    Do not use this version, there is a bug with the new "label distance" key.
+
     - Added options to fine-tune the position of labels and annotations
     - Added options to change arrow tips on variable resistors, inductors and
       capacitors as well as in potentiometers

 You can notice a pair of things here: first of all, the use of the \texttt{anchor=out} in the port, to tell \TikZ{} that we want the node moved so that the \texttt{out} anchor is the reference one. The second one is that we have repeated the absolute shift (the \texttt{++(-1, 0)}) twice. This is a bad practice; it is much better to have the ``free'' parameters of a schematic just stated once, so that we can change them in just one point.

 \paragraph{Core anchors.}\label{sec:inductors-core-anchors}
 Inductors have additional anchors to add core lines (for historical reasons, there is a \texttt{cute choke} component also, but to use inductors in the chosen style you better use these anchors). The anchors are called \texttt{core west} and \texttt{core east} and they are positioned at a distance that you can tweak with the \texttt{\textbackslash ctikzset} key \texttt{bipoles/inductors/core distance} (default \texttt{2pt}).
