v0.0.27

• Prevent changing the name of net 0 when generating a SPICE netlist.
• Fixed Pin, Net, Bus and Part iterators so they'll work in nested loops.
• Part units are automatically added when a part is parsed.
• Files are now opened for reading using latin_1 encoding to allow special symbols used by KiCad.
• Part pins can now be aliased directly, e.g. uc[5].aliases += 'gp0'.
• Added class method get() to Part to allow finding a part based on name, reference, description.
• Refactored ERC functions to allow user-extensibility.
• Created a base object for Circuit, Part, Pin, Net, and Bus objects.
• Added an aliases property to the SKiDL base object so all its children could be aliased.
• Updated to perform simulations with ngspice version 30.
• Added a notes property to allow attachment of user notes to Parts, Pins, Nets, etc.
• Added net class to net objects for specifying net-specific design rules in PCBNEW.
• Ignore multiple pins with the same number in symbols with DeMorgan equivalents.
• Fixed problem with non-ASCII chars (e.g. Ohms) in strings.
• Sped-up part/net naming using heap/cache, binary search, sets.
• Sped-up by storing net traversals to avoid recomputation.
• Fixed processing of slices in things like sdram['A[0:15]'].
• Sped-up part_search() by eliminating unnecessary part parsing.
• Improved schematic generation with graphviz.
• Search now allows AND/OR of parenthesized terms.
• New GUI for searching for parts and footprints.
• Footprint libraries to search are now selected from the global fp-lib-table file.
• KiCad library component field values are now stored in a dict in Part indexed by the field name or F0, F1, F2...
• KiCad library component field values are also stored as Part attributes using the field name or F0, F1, F2...
• Added p and n attributes to Part object to permit explicit reference to pin numbers or names.

v0.0.26

• search command 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.

v0.0.25

• Updated website.
• KISYSMOD is no longer used to find part libraries, only KICAD_SYMBOL_DIR is used now.

v0.0.24

• Fixed an error where creating a backup part library for a design would create extra pins attached to the nets.

v0.0.23

• Added Network objects to make it easy to create serial & parallel combinations of two-pin parts.
• SKiDL design hierarchy is now embedded in the KiCad netlist that's generated.

0.0.22

• Added Interface objects for storing complicated sets of I/O signals for subsystems.
• ERC no longer redundantly checks every segment of a multi-segment net and reports multiple errors.
• copy() function of Part, Bus, Pin, Net objects now returns a scalar object while copy(1) returns a list with one object.
• Bus, Pin, and Net objects now have iterators.
• Corrected initialization of KiCad library search paths.

v0.0.21

• Added pull() and fetch() methods for getting/creating existing/new Net and Bus objects.
• Added drive property to pins to override their default pin function attribute.
• Part pins and units can now be accessed as attributes.
• Nets, pins, and buses now support the width property.
• Indexing with brackets now works equivalently for pins, nets, and buses.
• Grouped part pins (such as address and data buses) can now be accessed using a slice-like notation, e.g. memory['ADDR[0:7]'].

v0.0.20

• Matching of pin lists now begins with normal string matching before using regexes.
• Added more tests and fixed existing tests.

v0.0.19

• 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.
• SPICE simulations of subcircuits (.SUBCKT) now supported.
• Improvements/additions to the library of supported SPICE parts.

v0.0.18

• SPICE simulations of circuits now supported (Python 3 only).
