Kikit

This release brings some new features:

- KiKit can now generate assembly files for [PCB Way](https://www.pcbway.com/) - this feature was implemented by maribu. Thanks!
- We did refactoring which allows us to support both, KiCAD v5 and KiCAD v6. However, the support of v6 (nightly) is experimental, and unfortunately, many features do not work, as KiCAD nightly does breaking changes to the API nearly every week. Once KiCAD v6 release candidate is out, you can expect better support.
- We support automated validation of design rules - you can check your boards and panels, e.g., in an automated way in CI. This feature works only with KiCAD 6.
- We established the basics for Action Plugin - currently, you can invoke hide/show references functionality from GUI. More commands are expected to be supported in the future.
- KiKit can generate cutouts in the stencils for already populated components. This is useful when you have already pre-populated board and you want to populate extra components.

It also fixes several bugs and small improvements:

- Assembly files now generate correct drill files when auxiliary origins are in use.
- The KiKit startup times were drastically reduced (from 1.68 seconds to 0.12 seconds)
- KiKit now ignores invisible labels of components, therefore, it does not throw away components from the boards.
- A bug in tight grid placement with rotated boards was fixed.
- Documentation was improved
- a note about running KiKit with a specific version of KiCAD was added
- FAQ was improved (e.g., detailed information about Windows support)
- Detailed installation instructions were added
- The Docker container with KiKit is based on Ubuntu 20.04 instead of Ubuntu 19.10

This is a small release that brings bug fixes for 67, 66, and 65.

To install this release, simply upgrade via `pip`.

This release brings some new features:

- KiKit supports new command: `kikit fab` which exports all manufacturing data for a given PCB manufacturer. It supports both, generation of gerbers, BOMs and POS files for automated assembly! Currently, we support a single manufacturer: JLC PCB. See the [documentation](https://github.com/yaqwsx/KiKit/blob/master/doc/fabrication.md) or simply try `kikit fab jlcpcb`

- KiKit now supports rails in addition to a frame. Just specify `--railsTb` or `--railsLr`. See documentation or the [examples](https://github.com/yaqwsx/KiKit/blob/master/doc/examples.md).

- KiKit can automatically generate tooling holes and fiducials in the corner of the panel - see options `--fiducials` and `--tooling` in the [examples](https://github.com/yaqwsx/KiKit/blob/master/doc/examples.md)

- an option `--copperfill` was implemented to fill unused areas of the panel with copper - see the [examples](https://github.com/yaqwsx/KiKit/blob/master/doc/examples.md).

It also brings some minor tweaks:

- KiKit versioning has been transferred to versionner to better track particular versions in upstream installations

- KiKit now checks for PCB thickness and warns you, when you mix different thickness of PCB. It also transfers the thickness to the resulting panel.

- the gerber export was changed to use conservative settings to be compatible with more PCB manufacturers

We also fixed a bug:

- when you created a panel with no spacing, it missed outer cuts. This is now fixed.

Changelog

- when there are footprints with Edge.Cuts inside, this geometry is no longer ignored
- the tolerance option for enlarging implicit source area was added
- fiducial and tooling hole support was implemented. Currently, it is only accessible from Python API, not CLI
- you can specify tab positions by drawing lines on a layer in KiCAD
- fillets are now applied to the frame
- a bug in the fillet feature, when narrow slot disappeared, was fixed
- KiKit now correctly supports multi-layered boards
- KiKit supports exporting 3D printed solder stencils
- Kikit supports exporting steel stencils for an alignment jig
- the user can enable adding mouse bites to the frame for easier manipulation
- Documentation was improved, FAQ was added
