v0.0.17

• Modularized code into separate files.

v0.0.16

• Parsing of KiCad EESchema libraries made more robust.
• DEFAULT_TOOL replaced with set_default_tool() function.
• Some code simplification by using a context manager for opening files.

v0.0.15

• Testing made more robust.

v0.0.14

• KiCad netlists are now parsed using the external package kinparse.
• Cleaned-up pylint-identified issues.
• Removed absolute file paths to libraries from tests.

v0.0.13

• Fixed problem where the search function was only returning parts found in the last library searched.

v0.0.12

• Use of builtin now works with Python 2 & 3.
• Started using namedtuple in some places (like net traversal) for clarity.
• Corrected pin-to-pin connections so if a net is created, it goes into the same Circuit the pins are members of.
• Part templates can now contain a reference to a Circuit object that will be applied when the template is instantiated.
• When pins are connected to nets, or nets to nets, the resulting set of connected nets are all given the same name.
• Buses are not added to a Circuit object if they are already members of it. This fix caused the next problem.
• Buses weren't getting added to the Circuit object because they already contained a reference to the Circuit. Fixed by clearing ref before adding to Circuit.
• Created mini_reset() method to clear circuitry without clearing library cache so the libraries don't have to be loaded again (slow).
• search() utility now prints the names of libraries as they are searched so user sees progress.
• Fixed exceptions if part definition contained non-unicode stuff.
• Hide exceptions that occur when using the show() utility.
• More tests added for NC nets and hand-crafted parts.
• default_circuit and the NC net for the active circuit are now made accessible in all modules using builtin.
• Corrected error messages that referenced wrong/non-existing variable.
• Inserted NO_LIB for the library if it doesn't exist when generating KiCad netlists or XML.
• Attributes can now be passed when creating a Circuit object.
• Pins are now associated with part when added to the part.
• Minimum and maximum pins for a part are now computed as needed.
• Each Circuit object now has its own NC net.
• Added tests for bus movement and copying.
• Implemented bus movement between Circuit objects.
• Additional test cases were created.
• Nets and Parts can now be removed from Circuits.
• The circuit that pins and nets are in is now checked before connections are made so cross-circuit connections are not created.
• Default members were added to Pin and Part objects so they would always exist and not cause errors when missing.
• Implemented moving Parts and Nets from one circuit to another (almost).
• Nets with no attached pins are now added to a circuit.
• Re-wrote some tests to account for the presence of no-pin nets in a circuit.
• A class method was missing its 'self' argument.
• Fixed @Subcircuit decorator so it won't cause an error if the function it decorates doesn't have a 'circuit' keyword argument.
• Split the unit tests across multiple files. Added setup/teardown code.
• Added capability to create multiple, independent Circuit objects to which Parts and Nets can be assigned. The default circuit is still the target if not Circuit is explicitly referenced.
• Added IOError to exception list for opening a SKiDL part library.

v0.0.11

• Part libraries in SKiDL format are now supported.
• Parts can now be created on-the-fly and instantiated or added to libraries.
• The parts used in a circuit can be stored in a backup SKiDL library and used if the original libraries are missing.
• The KiCad standard part libraries were converted to SKiDL libraries and placed in skidl.libs.

v0.0.10

• Nets without pins can now be merged.
• Parts and Pins are now sorted when netlists are generated.
• For an existing Bus, new bus lines can be inserted at any position or the bus can be extended.

v0.0.9

• Use getattr() instead of class.dict so that subclasses of SKiDL objects
  can find attributes named within strings without searching the mor.

v0.0.8

• skidl_to_netlist now uses templates.
• Default operation of search() is now less exacting.
• Traceback is now suppressed if show() is passed a part name not in a library.
