- Added p and n attributes to Part object to permit explicit reference to pin numbers or names.
searchcommand no longer looks in backup library because that leads to erroneous hits in all libraries.- Part objects will now iterate through their pins and len() will return the number of pins.
- Updated netlist_to_skidl utility to account for new version of kinparse.
- Updated website.
- KISYSMOD is no longer used to find part libraries, only KICAD_SYMBOL_DIR is used now.

- Matching of pin lists now begins with normal string matching before using regexes.
- Added more tests and fixed existing tests.
- Selecting part pins now looks for exact match before falling back to regex matching.
- PySpice now needs to be manually installed to perform SPICE simulations.

- 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.
- Testing made more robust.
- KiCad netlists are now parsed using the external package kinparse.
- Cleaned-up pylint-identified issues.
- Removed absolute file paths to libraries from tests.
- Fixed problem where the search function was only returning parts found in the last library searched.
- 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.

- 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.

- 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.
- 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.
- Use getattr() instead of __class__.__dict__ so that subclasses of SKiDL objects can find attributes named within strings without searching the __mor__.

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

- First release on PyPI.
