%DO NOT EDIT THIS AUTOMATICALLY GENERATED FILE, run "make changelog" at toplevel!!! 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 1.3.5 (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. \begin{itemize} \tightlist \item Added support for creating and using sub-circuits \item Added UJT transistors and GTO devices (\href{https://github.com/circuitikz/circuitikz/issues/522}{suggested by JetherReis}) \item Added (as an option) a different, more compact style for thyristor-type devices. \item Added a photovoltaic module (\href{https://github.com/circuitikz/circuitikz/issues/524}{suggested by André Alves}) \item Added a DC/DC converter block for symmetry (\href{https://github.com/circuitikz/circuitikz/issues/529}{suggested by Pratched}) \item Added the possibility to change the waveforms shown in the oscilloscope (\href{https://tex.stackexchange.com/q/595062/38080}{suggested by Mario Tafur}) \item 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. \begin{itemize} \tightlist \item Added separate configuration for the line thickness of resistors, capacitors, and inductors modifiers \item Added ferroelectric capacitors and ferroelectric gate MOS/FETs (\href{https://github.com/circuitikz/circuitikz/issues/515}{suggested by Mayeul Cantan}) \item Added an option to fill the gate gap in MOSes, FETs and IGBTs with a color \item Added a ``centergap'' anchor for transistors \item Added the option ``nogate'' to the \texttt{hemt} symbol \item Fixed a bug in thermistors not respecting their class line thickness \item Fixes in the manual (copy and paste of snippets without numbers, correct old usage of \texttt{siunitx}, factor out repetitions in the preamble; \href{https://tex.stackexchange.com/a/57160/38080}{thanks to Ulrike Fischer}. \item Fixed a bug introduced in 1.3.3 that would reduce compatibility with 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). Some of the arrow shapes are now configurable. Do not use this version, there is a bug with the new ``label distance'' key. \begin{itemize} \tightlist \item Added options to fine-tune the position of labels and annotations \item Added options to change arrow tips on variable resistors, inductors and capacitors as well as in potentiometers \item Added options to change arrow tips on switches \item Added anchors to inductance to add core lines \item Fixed the default direction of tunable arrows (with an option to go back to the old ones) \end{itemize} \item Version 1.3.2 (2021-03-14) \begin{itemize} \tightlist \item Added the simplified (2-waves) highpass and lowpass blocks \item Added graphene FETs (suggested by Cees Keyer) \item Added left/right anchors to transistors \item Fixed a \href{https://tex.stackexchange.com/q/587213/38080}{bug in flip-flops} \end{itemize} \item Version 1.3.1 (2021-02-20) \begin{itemize} \tightlist \item Fixed a bug in ``fuse'' and ``afuse'' fill \item Remove the voltage direction warning. Nobody really ever cared \item Minor fixes and enhancements to the manual \end{itemize} \item Version 1.3.0 (2021-01-19) \begin{itemize} \tightlist \item Fixed a long-standing problem with labels and similar decoration with equal signs and commas \item Fixed a typo in the manual (thanks to @muzimuzhi on GitHub) \item The Mother of All Code Refactoring: no real changes (modulo errors) \item Added a rollback point to 1.2.7 \end{itemize} \item Version 1.2.7 (2020-12-27) Bugfix release. \begin{itemize} \tightlist \item The recent temporary changes to TikZ to v3.1.8a revealed a problem in corner cases with \texttt{circuitikz} that should be fixed (thanks to Henri Menke) \end{itemize} \item Version 1.2.6 (2020-12-16) The highlight of this release is the option to draw circles around transistors; moreover, a handful of new component and several bug fixes. \begin{itemize} \tightlist \item added option to have transistors with circles, suggested by user \texttt{@myzinsky} \item added closed position for normally open button and the other way around (suggested by user \texttt{@septatrix}) \item added a \texttt{tip} anchor for push buttons \item added text anchor for legacy \texttt{linestub} component \item added an option for a different style of european logic xnor port (suggested by user \texttt{@Schlepptop}) \item added dynode tubes electrodes (suggested by user \texttt{@ferdymercury}) \item fixed a bug in style-files (thanks to user \texttt{@Alex} on \texttt{tex.stackexchange.com}) \item added a comment about relative coords (thanks to user \texttt{@septatrix}) \item several fixes to the manual \end{itemize} \item Version 1.2.5 (2020-10-14) Mainly a bugfix release for \texttt{raised} voltage style. \begin{itemize} \tightlist \item added macro to access labels and annotations anchors and direction \item fixed a bug in ``raised'' voltages' positions with \texttt{invert} and/or \texttt{mirror} \end{itemize} \item Version 1.2.4 (2020-10-04) \begin{itemize} \tightlist \item several documentation enhancment \item added a couple of block elements: allpass filter, generic two-sides block (suggested by user \texttt{@myzinsky}) \item added transmission gate (only IEEE style version) suggested by several users (\texttt{@SJulianS} on github, Philipp Birkl on \texttt{TeX.SX}) \item added a resistive splitter block symbol by \texttt{@matthuszagh} \item added depletion-type \texttt{nmosd} and \texttt{pmosd} MOSFET simplified symbols \item added depletion-type \texttt{nfetd} and \texttt{pfetd} for plain full-symbol MOSFET \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 add an \texttt{open\ poles\ fill} option to simplify circuits where the background is different from white \item restyled the FAQ and added the explanation of ``gaps with \texttt{nodes}'' that happens again after 1.2.1 \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 Fixed some bipole border size to avoid overlapping labels; document 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 Jérôme 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 Radványi Patrik Tamás) \item added open barrier bipole (suggested by Radványi Patrik Tamás) \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 Schrödinger'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 Added a style to switch off the automatic rotation of instruments \item Changed the shape of the or-type american logic ports (reversible 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 Make plus and minus symbol on amplifiers configurable \item Adjusted the position of text in triangular amplifiers \item Fixed ``plain amp'' not respecting ``noinv input up'' \item Fixed minor incompatibility with ConTeXt and Plain TeX \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 internal font changing commands for compatibility with ConTeXt \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. \begin{itemize} \tightlist \item Fixed a bug with ``inline'' gyrators, now the circle will not overlap \item Fixed a bug in input anchors of european not ports \item Fixed ``tlinestub'' so that it has the same default size than ``tline'' (TL) \item Fixed the ``transistor arrows at end'' feature, added to styling \item Changed the behavior of ``voltage shift'' and voltage label positioning to be more robust \item Added several new anchors for ``elmech'' element \item Several minor fixes in some component drawings to allow fill and thickness styles \item Add 0.9.3 version snapshots. \item Added styling of relative size of components (at a global or local level) \item Added styling for fill color and thickeness \item Added style files \end{itemize} \item Version 0.9.3 (2019-07-13) \begin{itemize} \tightlist \item Added the option to have ``dotless'' P-MOS (to use with arrowmos option) \item Fixed a (puzzling) problem with coupler2 \item Fixed a compatibility problem with newer PGF (\textgreater{}3.0.1a) \end{itemize} \item Version 0.9.2 (2019-06-21) \begin{itemize} \tightlist \item (hopefully) fixed ConTeXt compatibility. Most new functionality is not tested; testers and developers for the ConTeXt side are needed. \item Added old ConTeXt version for 0.8.3 \item Added tailless ground \end{itemize} \item Version 0.9.1 (2019-06-16) \begin{itemize} \tightlist \item Added old LaTeX versions for 0.8.3, 0.7, 0.6 and 0.4 \item Added the option to have inline transformers and gyrators \item Added rotary switches \item Added more configurable bipole nodes (connectors) and more shapes \item Added 7-segment displays \item Added vacuum tubes by J. op den Brouw \item Made the open shape of dcisources configurable \item Made the arrows on vcc and vee configurable \item Fixed anchors of diamondpole nodes \item Fixed a bug (\#205) about unstable anchors in the chip components \item Fixed a regression in label placement for some values of scaling \item Fixed problems with cute switches anchors \end{itemize} \item Version 0.9.0 (2019-05-10) \begin{itemize} \tightlist \item Added Romano Giannetti as contributor \item Added a CONTRIBUTING file \item Added options for solving the voltage direction problems. \item Adjusted ground symbols to better match ISO standard, added new symbols \item Added new sources (cute european versions, noise sources) \item Added new types of amplifiers, and option to flip inputs and outputs \item Added bidirectional diodes (diac) thanks to Andre Lucas Chinazzo \item Added L,R,C sensors (with european, american and cute variants) \item Added stacked labels (thanks to the original work by Claudio Fiandrino) \item Make the position of voltage symbols adjustable \item Make the position of arrows in FETs and BJTs adjustable \item Added chips (DIP, QFP) with a generic number of pins \item Added special anchors for transformers (and fixed the wrong center anchor) \item Changed the logical port implementation to multiple inputs (thanks to John Kormylo) with border anchors. \item Added several symbols: bulb, new switches, new antennas, loudspeaker, microphone, coaxial connector, viscoelastic element \item Make most components fillable \item Added the oscilloscope component and several new instruments \item Added viscoelastic element \item Added a manual section on how to define new components \item Fixed american voltage symbols and allow to customize them \item Fixed placement of straightlabels in several cases \item Fixed a bug about straightlabels (thanks to @fotesan) \item Fixed labels spacing so that they are independent on scale factor \item Fixed the position of text labels in amplifiers \end{itemize} \item Version 0.8.3 (2017-05-28) \begin{itemize} \tightlist \item Removed unwanted lines at to-paths if the starting point is a node without a explicit anchor. \item Fixed scaling option, now all parts are scaled by bipoles/length \item Surge arrester appears no more if a to path is used without {[}{]}-options \item Fixed current placement now possible with paths at an angle of around 280° \item Fixed voltage placement now possible with paths at an angle of around 280° \item Fixed label and annotation placement (at some angles position not changable) \item Adjustable default distance for straight-voltages: `bipoles/voltage/straight label distance' \item Added Symbol for bandstop filter \item New annotation type to show flows using f=\ldots{} like currents, can be used for thermal, power or current flows \end{itemize} \item Version 0.8.2 (2017-05-01) \begin{itemize} \tightlist \item Fixes pgfkeys error using alternatively specified mixed colors(see pgfplots manual section ``4.7.5 Colors'') \item Added new switches ``ncs'' and ``nos'' \item Reworked arrows at spst-switches \item Fixed direction of controlled american voltage source \item ``v\textless{}='' and ``i\textless{}='' do not rotate the sources anymore(see them as ``counting direction indication'', this can be different then the shape orientation); Use the option ``invert'' to change the direction of the source/apperance of the shape. \item current label ``i='' can now be used independent of the regular label ``l='' at current sources \item rewrite of current arrow placement.
