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 1.7.0 (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.

    • New component: new kind of current tap (suggested by EEpchi and Dr4UX on GitHub)
    • New arrow tip Jack Tap to help drawing jack connectors (suggested by Anisio Rogerio Braga)
    • Change the drawing of the thermocouple (suggested by Dr4UX on GitHub)
    • Change and enhancement to the drawing of the American resistors (triggered by Dr4UX on GitHub), fixing a long-standing small asymmetry that nobody noticed
    • Minor adjustment for joins in viscoe component
    • Minor additions (rectjoinfill) and fixes in documentation

  • Version 1.6.9 (2024-05-25)

    Several new components and a bug fix for a nasty long-standing bug about switching diode types.

  • Version 1.6.8 (2024-05-05)

    Several new components, more anchors, a bit of documentation enhancement; maybe the biggest change is the new "flexible" tube.

  • Version 1.6.7 (2024-02-09)

    Several new blocks, more flexible generic anchors for blocks, and a new option to align the signs on american-style voltage sources.

    • Added saturation block (contributed by P. Sacco [email protected])
    • Added iamp, sigmoid, and allornothing blocks
    • Added optical fiber fiber (contributed by Christopher Beck)
    • Now the position of the lateral anchors (left up and similar) of blocks is configurable (suggested by user "sputeanus" on GitHub)
    • Now you can choose how the signs on american-style sources rotate when the source is not vertical (suggested by jotagah on GitHub)
    • New section in the manual about related packages

  • Version 1.6.6 (2023-12-09)

    Several new components.

    • Added the symbol for metal-oxide varistor mov
    • Added another symbol for fuse (wiggly fuse wfuse)

  • Version 1.6.5 (2023-10-29)

    This version features an important overhaul of the muxdemux configurable component/shape, making it much more flexible and powerful, by adding configurable labels and negation and clock symbols to the pins. Also, a couple of minor fixes/workarounds.

    • Added optional and configurable inner, outer and border labels to the muxdemux shapes
    • Added optional clock wedge and negation signs to the pins of muxdemux shapes

    • Added configurable open shape to the sinusoidal current source (contributed by Maximilian Martin)
    • Documentation fixes

  • 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.

    • Change the definition of the "minus" symbol (see this issue) for details
    • Add documentation on how to contact the border of the source symbols (suggested by user @Tipounk on GitHub)
    • in transistors, solder dots and connection dots for body diodes are now configurable

  • 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 siunitx layer compatibility macros.

  • 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 tline.

    • Correction of several typo/grammar errors in the documentation by quark67

  • Version 1.6.0 (2022-12-10)

    The big change is the refactoring (and enhancement) of the block's code. In addition, double gate MOSes, several fixes all over the map, and quite a lot of anchors were added into the mix.

    • Big change (mostly backward compatible, minus a couple of bug fixes) to the block's code.
      • Now vco can be boxed
      • enabled more short-name geographical anchors
      • generic blocks can be made rectangular

    • Added Shockley diode (suggested by @dauph)

  • Version 1.5.2 (2022-05-08)

    Adding a couple of new component and a nice feature to transistors and tubes.

  • Version 1.5.1 (2022-04-26)

    Bug fix release.

  • Version 1.5.0 (2022-04-22)

    In this version, several internal changes have been included in order to streamline and organize better the components and to change the management of color. The changes are pretty deep and subtle, so a bug 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.

    Internal changes:

    • Added a generic drawing function for shapes, which are now drawn always in background
    • Added a hook system to be able to change component drawing settings per-shape, per-class or globally
    • All the 250+ shapes are now "protected" by possible external arrow and arced corners parameters
    • Completely changed the management of the shapes' color, thanks to GitHub user muzimuzhi

  • Version 1.4.6 (2022-02-04)

    A nasty bug fix and some hack to avoid that some global TikZ 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.

    • Fix bug with legacy transmission lines in overlays (noticed by Benedikt Wilde)
    • Robustify some shapes: do not let arrows option pass to the inner drawing (see here and here)
    • Add warning about global draw options in the manual
    • Fixes in documentation: hyperlink the index again, cite new recovery point, remove some legacy construct
    • Added 1.4.6 rollback point

  • Version 1.4.5 (2021-12-06)

    Important fix for ConTeXt users, thanks to @TeXnician for reporting.

    • Fixed an incompatibility introduced with subcircuits that made compilation in ConTeXt fail
    • Added \ctikzflip[x][y] utility macros for ConTeXt too
    • Fixed stray characters in some TikZ environment

  • Version 1.4.4 (2021-10-31)

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

  • Version 1.4.3 (2021-09-06)

    Minor release, mainly a single bugfix.

    • added hidden anchors of ooosource to the manual
    • fix a bug in anchors of ooosource (they did not respect class scaling)
    • faster use fpu reciprocal (thanks to Henri Menke)

  • 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).

    • add the cpe (constant phase element)
    • correct minor errors in the manual (capacitor's fill, spaces) and the code.

  • 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 +, like +(1,1). Moreover, the possibility to have voltage, current and flow labels without the symbols (arrows, etc) has been added, which greatly simplify some kind of personalization of these elements.

  • Version 1.4.0 (2021-07-06)

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

    • bump version to 1.4.0
    • implement the version rollback: time travel to 0.4!
    • remove a wrong movement in the path construction (potentially dangerous)

  • Version 1.3.9 (2021-06-27)

    Bugfix release: open poles opacity was not working in most of the cases.

  • Version 1.3.8 (2021-06-15)

    The big news of this release is the ability to selectively draw the pins of the integrated circuit and mux-demuxes symbols.

    • Add draw only pins feature to dipchip and qfpchip, thanks to Jonathan P. Spratte, and a similar option to control the pins of muxdemux
    • Make dipchip and qfpchip respect no input leads option
    • Several corrections to the manual

  • version 1.3.7 (2021-06-01)

    Minor release, mainly documentation upgrades.

    • New options for the line thickness, rotation and size of symbols drawn in sources
    • New tutorial: drawing a circuit around an operational amplifier
    • Documentation fixes and small enhancements

  • version 1.3.6 (2021-05-09)

    Mainly a bugfix release; fixing a bug in the 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).

    • Added stacked annotations for symmetry with stacked labels.
    • Fixed a bug in the plotting of inst amp ra terminals.
    • Fixed a bug in managing stacked labels (l2=...); possibly it will be mildly backward-incompatible (please see the manual about incompatible changes)

  • 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 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.

    • Added support for creating and using sub-circuits
    • Added UJT transistors and GTO devices (suggested by JetherReis)
    • Added (as an option) a different, more compact style for thyristor-type devices.
    • Added a photovoltaic module (suggested by André Alves)
    • Added a DC/DC converter block for symmetry (suggested by Pratched)
    • Added the possibility to change the waveforms shown in the oscilloscope (suggested by Mario Tafur)
    • In the manual, separate the component usage chapter from the big component list
    • Fix wrong rotary switch "in" anchors for switches with more than 180 degrees coverage (see bug)

  • 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 TikZ 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)

    • 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.
    • Fixed a bug introduced in 1.3.3 that would reduce compatibility with the circuits internal library; reported by JetherReis)

  • 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
    • Added options to change arrow tips on switches

    Mainly a bugfix release for raised voltage style.

    • added macro to access labels and annotations anchors and direction
    • fixed a bug in "raised" voltages' positions with invert and/or mirror

  • Version 1.2.4 (2020-10-04)

    • several documentation enhancment
    • added a couple of block elements: allpass filter, generic two-sides block (suggested by user @myzinsky)
    • added transmission gate (only IEEE style version) suggested by several users (@SJulianS on github, Philipp Birkl on TeX.SX)
    • added a resistive splitter block symbol by @matthuszagh
    • added depletion-type nmosd and pmosd MOSFET simplified symbols
    • added depletion-type nfetd and pfetd for plain full-symbol MOSFET

  • 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.

    • added a Mach-Zehnder-Modulator block symbol as node mzm by user @dl1chb
    • add an open poles fill option to simplify circuits where the background is different from white

    • Block anchors: add border anchors for round elements and deprecate old 1, 2, 3, 4 anchors
    • Fixed some bipole border size to avoid overlapping labels; document it

  • 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.

  • Version 1.2.1 (2020-07-06)

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

    From the user point of view:

    • there is now a new style of voltages ("raised American")
    • a powerful mechanism for customize voltages, current and flows has been added.

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

    • Added access to voltages, currents and flows anchors
    • Added "raised american" voltage style
    • Rewrite of the path generation macros
    • Several small bugs fixed (no one ever used some "f^>" options...)

  • 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.

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

  • Version 1.1.2 (2020-05-17)

    • Blocks and component for three-phase networks (3-lines wire, AC/DC and DC/AC converters blocks and grid node block) added by user @olfline on GitHub
    • added transformer sources with optional vector groups for three-phase networks by @olfline on Github
    • added subsections to the examples
    • fixed position of american voltages on open circuits (suggested by user @rhandley on GitHub)

  • Version 1.1.1 (2020-04-24)

    One-line bugfix release for the IEEE ports "not" circle thickness

  • 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.

    • added IEEE standard logic ports suggested by user Jason-s on GitHub
    • added configurability to european logic port "not" output symbol, suggested by j-hap on GitHub
    • added inerter component by user Tadashi on GitHub
    • added variable outer base height for IGBT, suggested by user RA-EE on GitHub

    • fixed formatting of CHANGELOG.md

  • Version 1.0.1 (2020-02-22)

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

    • add v1.0 version snapshots
    • added crossed generic impedance (suggested by Radványi Patrik Tamás)
    • added open barrier bipole (suggested by Radványi Patrik Tamás)
    • added two flags to flip the direction of light's arrows on LED and photodiode (suggested by karlkappe on GitHub)
    • 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 Schrödinger's cat for finding a fix)
    • fixed a nasty bug for the flat file generation for ConTeXt

  • Version 1.0 (2020-02-04)

    And finally... version 1.0 (2020-02-04) of 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:

    • The manual has been reorganized and extended, with the addition of a tutorial part; tens of examples have been added all over the map.
    • 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.
    • 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.
    • 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).
    • 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.

A detailed list of changes can be seen below.

  • Version 1.0.0-pre3 (not released)

    • Added a Reed switch
    • Put the copyright and license notices on all files and update them
    • Fixed the loading of style; we should not guard against reload

  • Version 1.0.0-pre2 (2020-01-23)

    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.

    • Added mux-demux shapes
    • Added the possibility to suppress the input leads in logic gates
    • Added multiple wires markers
    • Added a style to switch off the automatic rotation of instruments
    • Changed the shape of the or-type american logic ports (reversible with a flag)

  • 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.

    • Added a flip-flop library
    • Added a single-input generic amplifier with the same dimension as "plain amp"
    • Added border anchors to amplifiers
    • Added the possibility (expert only!) to add transparency to poles (after a suggestion from user @matthuszagh on GitHub)
    • Make plus and minus symbol on amplifiers configurable
    • Adjusted the position of text in triangular amplifiers
    • Fixed "plain amp" not respecting "noinv input up"
    • Fixed minor incompatibility with ConTeXt and Plain TeX

  • 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 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.

    • Added multi-collectors and multi-emitter bipolar transistors
    • Added the possibility to style each one of the two coils in a transformer independently
    • Added bulk connection to normal MOSFETs and the respective anchors
    • Added "text" anchor to the flow arrows, to use them alone in a consistent way
    • Fixed flow, voltage, and current arrow positioning when "auto" is active on the path
    • Fixed transistors arrows overshooting the connection point, added a couple of anchors
    • Fixed a spelling error on op-amp key "noinv input down"
    • Fixed a problem with "quadpoles style=inner" and "transformer core" having the core lines running too near

  • 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 @TheTeXnician and @hmenke on github.com.

    • Added a "midtap" anchor for coils and exposed the inner coils shapes in the transformers
    • Added a "curved capacitor" with polarity coherent with "ecapacitor"
    • Added the possibility to apply style and access the nodes of bipole's text ornaments (labels, annotations, voltages, currents and flows)
    • Added the possibility to move the wiper in resistive potentiometers
    • Added a command to load and set a style in one go
    • Fixed internal font changing commands for compatibility with ConTeXt
    • Fixed hardcoded black color in "elko" and "elmech"

  • 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 unless you used voltage shift introduced in 0.9.0, which was broken when using the global 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 pgfcirc.defines.tex; so a snapshot for the 0.9.3 version is available.
