After three years since version 1.0, today marks the release of SKiDL version 2.0.0. The increment in the major version number indicates that this release is not backward compatible with previous versions, so some SKiDL code may not work if:

1. It relies on Python 2 (which is is no longer supported).
2. It uses the @package decorator (which was dropped).

If either of these things are important to you, then stick with version 1.2.3.

Here's a list of other changes in 2.0.0:

• Additional Part attributes can be specified when exporting libraries.
• A unexpio dict has been to Interface objects for accessing I/O without buses expanded into individual nets.
• connect() and __iadd__() methods were added to allow interconnection of Interface objects.
• Part libraries are pickled when first loaded for faster access on subsequent accesses. The directory for storing the pickled library files is specified in the SKiDL configuration file.
• The KICAD tool identifier now points to KICAD8.
