<!--- 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 0.8.2 (2017-05-01)
	- Fixes pgfkeys error using alternatively specified mixed colors(see pgfplots manual section "4.7.5 Colors")
	- Added new switches "ncs" and "nos"
	- Reworked arrows at spst-switches
	- Fixed direction of controlled american voltage source
	- "v<=" and "i<=" 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.
	- current label "i=" can now be used independent of the regular label "l=" at current sources
	- rewrite of current arrow placement. Current arrows can now also be rotated on zero-length paths
	- New DIN/EN compliant operational amplifier symbol "en amp"
	
* Version 0.8.1 (2017-03-25)
	- Fixed unwanted line through components if target coordinate is a name of a node
	- Fixed position of labels with subscript letters.
	- Absolute distance calculation in terms of ex at rotated labels
	- Fixed label for transistor paths (no label drawn)
	
* Version 0.8 (2017-03-08)
	- Allow use of voltage label at a [short]
	- Correct line joins between path components (to[...])
	- New Pole-shape .-. to fill perpendicular joins
	- Fixed direction of controlled american current source
	- Fixed incorrect scaling of magnetron
	- Fixed: Number of american inductor coils not adjustable
	- Fixed Battery Symbols and added new battery2 symbol
	- Added non-inverting Schmitttrigger

* Version 0.7 (2016-09-08)
	- Added second annotation label, showing, e.g., the value of an component
	- Added new symbol: magnetron
	- Fixed name conflict of diamond shape with tikz.shapes package
	- Fixed varcap symbol at small scalings
	- New packet-option "straightvoltages, to draw straight(no curved) voltage arrows
	- New option "invert" to revert the node direction at paths
	- Fixed american voltage label at special sources and battery
	- Fixed/rotated battery symbol(longer lines by default positive voltage)
	- New symbol Schmitttrigger

* Version 0.6 (2016-06-06)
	- Added Mechanical Symbols (damper,mass,spring)
	- Added new connection style diamond, use (d-d)
	- Added new sources voosource and ioosource (double zero-style)
	- All diode can now drawn in a stroked way, just use globel option "strokediode" or stroke instead of full/empty, or D-. Use this option for compliance with DIN standard EN-60617
	- Improved Shape of Diodes:tunnel diode, Zener diode, schottky diode (bit longer lines at cathode)
	- Reworked igbt: New anchors G,gate and new L-shaped form Lnigbt, Lpigbt
	- Improved shape of all fet-transistors and mirrored p-chan fets as default, as pnp, pmos, pfet are already. This means a backward-incompatibility, but smaller code, because p-channels mosfet are by default in the correct direction(source at top). Just remove the 'yscale=-1' from your p-chan fets at old pictures.

* Version 0.5 (2016-04-24)
	- new option boxed and dashed for hf-symbols
	- new option solderdot to enable/disable solderdot at source port of some fets

	- corrected voltage and current direction(option to use old behaviour)
	- option to show body diode at fet transistors

	- updated the email address
    - in documentation, fixed wrong (non-standard) labelling of the axis in an example (thanks to prof. Claudio Beccaria)

Borsche)
	- njfet, pjfet (contribution of Danilo Piazzalunga)
	- pigbt, nigbt
	- *backward incompatibility* potentiometer is now the standard resistor-with-arrow-in-the-middle; the old potentiometer is now known as variable resistor (or vR), similarly to variable inductor and variable capacitor
	- triac, thyristor, memristor
	- new property "name" for bipoles
	- fixed voltage problem for batteries in american voltage mode
	- european logic gates
	- *backward incompatibility* new american standard inductor. Old american inductor now called "cute inductor"
	- *backward incompatibility* transformer now linked with the chosen type of inductor, and version with core, too. Similarly for variable inductor
	- *backward incompatibility* styles for selecting shape variants now end are in the plural to avoid conflict with paths

   	- *Backward incompatibility*: labels ending with \texttt{:}\textit{angle} are not parsed for positioning anymore.
	- Full use of \TikZ\ keyval features.
	- White background is not filled anymore: now the network can be drawn on a background picture as well.
	- Several new components added (logical ports, transistors, double bipoles, \ldots).
	- Color support.
	- Integration with {\ttfamily siunitx}.
	- Voltage, american style.
	- Better code, perhaps. General cleanup at the very least.
