The major changes among the different CircuiTikZ versions are listed
here. See \url{https://github.com/circuitikz/circuitikz/commits} for a
full list of changes.

\begin{itemize}
\item
  Version 1.7.2 (2025-03-21)

  A couple of new components (wiggly bulbs and a new ``oO'' type
  autotransformer), and several small corrections.

  \begin{itemize}
  \tightlist
  \item
    Fix leaking filament in \texttt{bulb} bipole
  \item
    Fix small incoherence between width/height in oo-type sources
  \item
    New component: Wiggly bulb (suggested by
    \href{https://github.com/circuitikz/circuitikz/issues/845}{Sebastiano})
  \item
    New component: ``zero-type'' autotransformer (suggested by
    \href{https://github.com/circuitikz/circuitikz/issues/852}{Max
    BÃ¶rjesson})
  \item
    Allow to set the index position for square instruments (by
    \href{https://github.com/circuitikz/circuitikz/pull/848}{Julien
    LabbÃ©})
  \end{itemize}
\item
  Version 1.7.1 (2025-01-10)

  Various new blocks have been added, and several fixes have been
  applied (the barrier one is slightly backward-incompatible\ldots).

  \begin{itemize}
  \tightlist
  \item
    Added a flag to have German style TVS (suggested by
    \href{https://github.com/circuitikz/circuitikz/issues/836}{Dr.~Matthias
    Jung}, implemented by Romano)
  \item
    Added many blocks all over the map (suggested by
    \href{https://github.com/circuitikz/circuitikz/issues/693}{Dr.~Matthias
    Jung}, with tweaks by Romano)
  \item
    Fix for straight voltage on \texttt{open} bipoles (reported by
    \href{https://github.com/circuitikz/circuitikz/issues/821}{Oliver
    Wallscheid on GitHub})
  \item
    Fix a very, very old bug about aliases for american/european sources
  \item
    Fix \texttt{barrier} wire linewidth (issue
    \href{https://github.com/circuitikz/circuitikz/issues/833}{\#833} by
    schtandard).
  \item
    Fix stroke-type transorb (which did not work at all)
  \item
    Reduce \texttt{barrier} and \texttt{openbarrier} default widths so
    no wire is drawn by default. This breaks backward-compatibility and
    changes the meaning of some associated keys, but the appearance with
    the default settings remains unchanged. See
    \href{https://github.com/circuitikz/circuitikz/pull/835}{\#835} for
    rationale.
  \item
    Documentation enhancement (example of chopper macro)
  \end{itemize}
\item
  Version 1.7.0 (2024-08-03)

  There are no big changes here, but the change to the resistor code
  (maybe one of the most used by the package) well deserves a minor
  version bump. A couple of new components, and several minor fixes.

    GitHub}), fixing a long-standing small asymmetry that nobody noticed
  \item
    Minor adjustment for joins in \texttt{viscoe} component
  \item
    Minor additions (\texttt{rectjoinfill}) and fixes in documentation
  \end{itemize}
\item

    \href{https://github.com/circuitikz/circuitikz/issues/747}{voltage
    shift mismatch} for sources
  \end{itemize}
\item
  Version 1.6.4 (2023-10-10)

  A bit of enhancement and fixes for the European-style logic ports,
  more switches (and a bit more configurabilityi for them), more option
  for some sources.

  \begin{itemize}
  \tightlist
  \item
    The symbol in European logic ports is now rotation-invariant, and
    its font can be customized (suggested by
    \href{https://github.com/circuitikz/circuitikz/issues/730}{user

    Martin})
  \item
    Documentation fixes
  \end{itemize}
\item
  Version 1.6.3 (2023-06-23)

  The main change is that the definition of the ``plus'' and ``minus''
  symbols used in several parts of the library has changed in order to
  achieve better alignment of voltages and amplifier symbols when using
  fonts different from Computer Modern. Additionally, internal
  connection dots in transistors are configurable and have a new
  default, and documentation has got several fixes and enhancements.

  \begin{itemize}
  \tightlist
  \item

    suggested by
    \href{https://github.com/circuitikz/circuitikz/issues/725}{user
    \texttt{@lapreindl} on GitHub}; the symbols have been slightly
    changed and repositioned in the process
  \item
    several documentation fixes
  \end{itemize}
\item
  Version 1.6.2 (2023-05-13)

  Several more styling options for elements (body diodes, transformers,
  crossing), a clock wedge shape for logical circuits, and documentation
  updates for ConTeXt, mainly noticing the (upstream) elimination of the
  thin \texttt{siunitx} layer compatibility macros.

  \begin{itemize}
  \tightlist
  \item
    There is no \texttt{siunitx} support for ConTeXt, point to the
    \texttt{units} package

    \texttt{@Mario1159} on GitHub})
  \end{itemize}
\item
  Version 1.6.1 (2023-02-11)

  New components: solder jumpers; a couple of small but very useful
  inversion markers for logical circuits, especially targeted at the
  mux-demux family; a new inline microphone; a much more versatile hemt;
  a better legacy \texttt{tline}. More tweaks to converters blocks, and
  a lot of typo/grammar fixes in the manual.

  \begin{itemize}
  \tightlist
  \item
    Add configurable dashes to the dc symbols in converter blocks
    (suggested by

  or unexpected behaviour is always possible. You can use the 1.4.6
  rollback point in case of trouble, but be sure to report any bug.

  \begin{itemize}
  \tightlist
  \item
    Added connectors shapes, and included the BNC into that class;
    thanks to

  Internal changes:

  \begin{itemize}
  \tightlist
  \item
    Added a generic drawing function for shapes, which are now drawn
    always in background
  \item
    Added a hook system to be able to change component drawing settings
    per-shape, per-class or globally

\item
  Version 1.4.6 (2022-02-04)

  A nasty bug fix and some hack to avoid that some global Ti\emph{k}Z
  option spill into the shapes. To better solve that problem, some risky
  changes are due, so this release will be also a rollback point for
  compatibility reasons.

  \begin{itemize}
  \tightlist
  \item
    Fix bug with legacy transmission lines in \texttt{overlay}s
    (\href{https://github.com/circuitikz/circuitikz/issues/604}{noticed
    by Benedikt Wilde})
  \item
    Robustify some shapes: do not let arrows option pass to the inner
    drawing (see
    \href{https://tex.stackexchange.com/a/632084/38080}{here} and
    \href{https://matrix.to/\#/!NuxCISwYQJuyWwNsEI:matrix.org/$vQO6luq1F66LJ79dERmaqKI46qMBcjStqYCPi725uZE?via=matrix.org&amp;via=2krueger.de&amp;via=im.f3l.de}{here})
  \item
    Add warning about global draw options in the manual
  \item
    Fixes in documentation: hyperlink the index again, cite new recovery
    point, remove some legacy construct
  \item
    Added 1.4.6 rollback point
  \end{itemize}
\item

  \end{itemize}
\item
  Version 1.4.4 (2021-10-31)

  Normal maintenance release; minor bugs fixed, a new component and a
  new option. No Halloween component, sorry\ldots{}

    open voltage label position}
  \end{itemize}
\item
  Version 1.4.3 (2021-09-06)

  Minor release, mainly a single bugfix.

  \end{itemize}
\item
  Version 1.4.2 (2021-07-26)

  This is a minor release, containing just a new component and a small
  set of fixes (mainly in the documentation).

  \begin{itemize}
  \tightlist
  \item
    add the \texttt{cpe} (constant phase element)

  \end{itemize}
\item
  Version 1.4.1 (2021-07-14)

  This version has an important bug fix for label positioning when
  once-relative style coordinates are used (the ones with a single
  \texttt{+}, like \texttt{+(1,1)}. Moreover, the possibility to have
  voltage, current and flow labels \emph{without} the symbols (arrows,
  etc) has been added, which greatly simplify some kind of
  personalization of these elements.

  \begin{itemize}
  \tightlist
  \item
    Added the generic tunable macro
  \item
    Added \texttt{no\ v\ symbols} (and also for \texttt{i} and

    position for +() style coordinates}
  \end{itemize}
\item
  Version 1.4.0 (2021-07-06)

  The main news is that \emph{package rollback} for \texttt{circuitikz}
  has been implemented (LaTeX-only, of course). Additionally, a small
  but important change in the path (\texttt{to}) construction that
  should fix some warning from Ti\emph{k}Z and give better line joins in
  wire corners.

  \begin{itemize}
  \tightlist
  \item
    bump version to 1.4.0
  \item
    implement the version rollback: time travel to 0.4!

    question by Florian H.} for details.
  \end{itemize}
\item
  Version 1.3.8 (2021-06-15)

  pins of the integrated circuit and mux-demuxes symbols.

  \begin{itemize}
  \tightlist
  \item
    Add \texttt{draw\ only\ pins} feature to \texttt{dipchip} and

    Spratte}, and a similar option to control the pins of
    \texttt{muxdemux}
  \item
    Make \texttt{dipchip} and \texttt{qfpchip} respect
    \texttt{no\ input\ leads} option
  \item
    Several corrections to the manual
  \end{itemize}
\item
  version 1.3.7 (2021-06-01)

  Minor release, mainly documentation upgrades.

  \end{itemize}
\item
  version 1.3.6 (2021-05-09)

  Mainly a bugfix release; fixing a bug in the \texttt{l2} stacked
  labels means that old constructs that were failing silently can give
  an error now. Sorry. To compensate, I added stacked annotation (for
  symmetry).

  \begin{itemize}
  \tightlist
  \item
    Added stacked annotations for symmetry with stacked labels.
  \item
    Fixed a bug in the plotting of \texttt{inst\ amp\ ra} terminals.
  \item
    Fixed a bug in managing stacked labels (\texttt{l2=...}); possibly
    it will be mildly backward-incompatible (please see the manual about
    incompatible changes)
  \end{itemize}
\item
  Version 1.3.5 (2021-05-02)

  Power electronics devices are the main characters in this release:
  PUT, GTOs, a new style for thyristors, and a photovoltaic module.
  Additionally, an \textbf{experimental} support for subcircuits has
  been added; it could change in the future. Fixed a nasty bug in rotary
  switches ``in'' anchor positioning in some cases.

    In the manual, separate the component usage chapter from the big
    component list
  \item
    Fix wrong rotary switch ``in'' anchors for switches with more than
    180 degrees coverage
    (\href{https://github.com/circuitikz/circuitikz/issues/532}{see
    bug})
  \end{itemize}
\item
  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\emph{k}Z \texttt{circuits}
  library (introduced in 1.3.3) has been fixed.

    the \texttt{circuits} internal library;
    \href{https://github.com/circuitikz/circuitikz/issues/519}{reported
    by JetherReis})
  \end{itemize}
\item
  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).

    (thanks to Henri Menke)
  \end{itemize}
\item
  Version 1.2.6 (2020-12-16)

  \end{itemize}
\item
  Version 1.2.3 (2020-08-07)

  Several fixes and small enhancement all over the map, changes in the
  documentation to better explain the reasons and effect of the
  path-building changes of 1.2.0 and 1.2.1.

  \begin{itemize}
  \tightlist
  \item
    added a Mach-Zehnder-Modulator block symbol as node \texttt{mzm} by
    user \texttt{@dl1chb}
  \item

  \item
    Fixed size of ``not circle'' in flip-flops to match european style
    \texttt{not\ circle} when used without the IEEE style
  \item
    Block anchors: add border anchors for round elements and deprecate
    old 1, 2, 3, 4 anchors
  \item

    it
  \end{itemize}
\item
  Version 1.2.2 (2020-07-15)

  Bug-fix release: coordinate name leakage. The node and coordinate
  names are global; the internal coordinate names have been made
  stronger.
\item
  Version 1.2.1 (2020-07-06)

  Several changes, both internal and user-visible. These are quite
  risky, although they \emph{should} be backward-compatible (if the
  circuit code is correct).

  From the user point of view:

  \begin{itemize}
  \tightlist
  \item
    there is now a new style of voltages (``raised American'')
  \item
    a powerful mechanism for customize voltages, current and flows has
    been added.
  \end{itemize}

  The internal changes are basically the re-implementation of the macros
  that draw the path elements (\texttt{to{[}...{]}}), which have been
  completely rewritten. Please be sure to read the possible
  incompatibilities in the manual (section 1.9).

  \begin{itemize}
  \tightlist
  \item
    Added access to voltages, currents and flows anchors
  \item
    Added ``raised american'' voltage style
  \item
    Rewrite of the path generation macros
  \item
    Several small bugs fixed (no one ever used some
    ``f\^{}\textgreater{}'' options\ldots)
  \end{itemize}
\item
  Version 1.2.0 (2020-06-21)

  In this release, the big change is the rewriting of the voltages
  output routine. Now all voltage options (american, european, and
  straight) take into account the shape (square border) of the
  component. The adjusting parameters are now (at least for passive
  elements) acting in similar way for all the options, too.

  \begin{itemize}
  \tightlist
  \item
    Bumped version number to 1.2 (potentially incompatible changes!)
  \item
    Added 1.1.2 checkpoint
  \item
    New path-style not, buffer, and Schmitt logic ports
  \item
    New tutorial (using the ``inline not'' component)
  \item
    Voltage output routine rewrite; now it takes into account the shape
    of the component also for ``american'' and ``straight'' voltages
  \item
    Several fixes in the logic ports: fixed IEEE \texttt{invschmitt}
    name, added symmetry to the three-style shorthands for the ports,
    and so on
  \item
    Fixed a gross bug in square poles anchor borders
  \item
    Fixed size of not circles in flip-flops (based on logic ports style)
  \item
    Fixed the order of initial options, to avoid ``european''
    overwriting single options
  \end{itemize}
\item
  Version 1.1.2 (2020-05-17)

  \begin{itemize}
  \tightlist
  \item
    Blocks and component for three-phase networks (3-lines wire, AC/DC
    and DC/AC converters blocks and grid node block) added by user
    \texttt{@olfline} on GitHub
  \item
    added transformer sources with optional vector groups for
    three-phase networks by \texttt{@olfline} on Github
  \item
    added subsections to the examples
  \item
    fixed position of american voltages on open circuits (suggested by
    user \texttt{@rhandley} on GitHub)
  \end{itemize}
\item
  Version 1.1.1 (2020-04-24)

  One-line bugfix release for the IEEE ports ``not'' circle thickness
\item
  Version 1.1.0 (2020-04-19)

  Version bumped to 1.1 because the new logic ports are quite a big
  addition: now there is a new style for logic ports, conforming to IEEE
  recommendations.

  Several minor additions all over the map too.

  \begin{itemize}
  \tightlist
  \item
    added IEEE standard logic ports suggested by user Jason-s on GitHub
  \item
    added configurability to european logic port ``not'' output symbol,
    suggested by j-hap on GitHub
  \item
    added \texttt{inerter} component by user Tadashi on GitHub
  \item
    added variable outer base height for IGBT, suggested by user RA-EE
    on GitHub
  \item
    added configurable ``+'' and ``-'' signs on american-style voltage
    generators
  \item
    text on amplifiers can be positioned to the left or centered
  \end{itemize}
\item
  Version 1.0.2 (2020-03-22)

  \begin{itemize}
  \tightlist
  \item
    added Schottky transistors (thanks to a suggestion by JÃ©rÃ´me
    Monclard on GitHub)
  \item
    fixed formatting of \texttt{CHANGELOG.md}
  \end{itemize}
\item
  Version 1.0.1 (2020-02-22)

  Minor fixes and addition to 1.0, in time to catch the freeze for
  TL2020.

  \begin{itemize}
  \tightlist
  \item
    add v1.0 version snapshots
  \item
    added crossed generic impedance (suggested by RadvÃ¡nyi Patrik TamÃ¡s)
  \item
    added open barrier bipole (suggested by RadvÃ¡nyi Patrik TamÃ¡s)
  \item
    added two flags to flip the direction of light's arrows on LED and
    photodiode (suggested by karlkappe on GitHub)
  \item
    added a special key to help with precision loss in case of
    fractional scaling (thanks to AndreaDiPietro92 on GitHub for
    noticing and reporting, and to SchrÃ¶dinger's cat for finding a fix)
  \item
    fixed a nasty bug for the flat file generation for ConTeXt
  \end{itemize}
\item
  Version 1.0 (2020-02-04)

  And finally\ldots{} version 1.0 (2020-02-04) of \texttt{circuitikz} is
  released.

  The main updates since version 0.8.3, which was the last release
  before Romano started co-maintaining the project, are the following
  --- part coded by Romano, part by several collaborators around the
  internet:

  \begin{itemize}
  \tightlist
  \item
    The manual has been reorganized and extended, with the addition of a
    tutorial part; tens of examples have been added all over the map.
  \item
    Around 74 new shapes where added. Notably, now there are chips,
    mux-demuxes, multi-terminal transistors, several types of switches,
    flip-flops, vacuum tubes, 7-segment displays, more amplifiers, and
    so on.
  \item
    Several existing shapes have been enhanced; for example, logic gates
    have a variable number of inputs, transistors are more configurable,
    resistors can be shaped more, and more.
  \item
    You can style your circuit, changing relative sizes, default
    thickness and fill color, and more details of how you like your
    circuit to look; the same you can do with labels (voltages,
    currents, names of components and so on).
  \item
    A lot of bugs have been squashed; especially the (very complex)
    voltage direction conundrum has been clarified and you can choose
    your preferred style here too.
  \end{itemize}
\end{itemize}

A detailed list of changes can be seen below.

\begin{itemize}
\item
  Version 1.0.0-pre3 (not released)

  \begin{itemize}
  \tightlist
  \item
    Added a Reed switch
  \item
    Put the copyright and license notices on all files and update them
  \item
    Fixed the loading of style; we should not guard against reload
  \end{itemize}
\item
  Version 1.0.0-pre2 (2020-01-23)

  \textbf{Really} last additions toward the 1.0.0 version. The most
  important change is the addition of multiplexer and de-multiplexers;
  also added the multi-wires (bus) markers.

  \begin{itemize}
  \tightlist
  \item
    Added mux-demux shapes
  \item
    Added the possibility to suppress the input leads in logic gates
  \item
    Added multiple wires markers
  \item

    with a flag)
  \end{itemize}
\item
  Version 1.0.0-pre1 (2019-12-22)

  Last additions before the long promised 1.0! In this pre-release we
  feature a flip-flop library, a revamped configurability of amplifiers
  (and a new amplifier as a bonus) and some bug fix around the clock.

  \begin{itemize}
  \tightlist
  \item
    Added a flip-flop library
  \item
    Added a single-input generic amplifier with the same dimension as
    ``plain amp''
  \item
    Added border anchors to amplifiers
  \item
    Added the possibility (expert only!) to add transparency to poles
    (after a suggestion from user @matthuszagh on GitHub)
  \item

  \end{itemize}
\item
  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.

  \begin{itemize}
  \tightlist
  \item
    Fix the position of transistor's text. There is an option to revert
    to the old behavior.
  \item
    Added anchors for adding circuits (like snubbers) to the flyback
    diodes in transistors (after a suggestion from @EdAlvesSilva on
    GitHub).
  \end{itemize}
\item
  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 transformers
  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}
\item
  Version 0.9.5 (2019-10-12)

  This release basically add features to better control labels, voltages
  and similar text ``ornaments'' on bipoles, plus some other minor
  things.

  On the bug fixes side, a big incompatibility with ConTeXt has been
  fixed, thanks to help from \texttt{@TheTeXnician} and \texttt{@hmenke}
  on \texttt{github.com}.

  \begin{itemize}
  \tightlist
  \item
    Added a ``midtap'' anchor for coils and exposed the inner coils
    shapes in the transformers
  \item
    Added a ``curved capacitor'' with polarity coherent with
    ``ecapacitor''
  \item
    Added the possibility to apply style and access the nodes of
    bipole's text ornaments (labels, annotations, voltages, currents and
    flows)
  \item
    Added the possibility to move the wiper in resistive potentiometers
  \item
    Added a command to load and set a style in one go
  \item

    Fixed hardcoded black color in ``elko'' and ``elmech''
  \end{itemize}
\item
  Version 0.9.4 (2019-08-30)

  This release introduces two changes: a big one, which is the styling
  of the components (please look at the manual for details) and a change
  to how voltage labels and arrows are positioned. This one should be
  backward compatible \emph{unless} you used \texttt{voltage\ shift}
  introduced in 0.9.0, which was broken when using the global
  \texttt{scale} parameter.

  The styling additions are quite big, and, although in principle they
  are backward compatible, you can find corner cases where they are not,
  especially if you used to change parameters for
  \texttt{pgfcirc.defines.tex}; so a snapshot for the 0.9.3 version is
  available.
