Kikit

This release contains no new features, just bug fixes, and improves compatibility with KiCAD 8.

- if KiCAD didn't create `kicad_dru` file for a board, KiKit crashed. This is fixed (3cb3720106e0b598ccb44a6b684f5dbbf9a76f38)
- we fixed arc welder, thus the option `--post 'reconstructarcs: true'` now works correctly (18b590ebe2d6fcaefb510f7782aa06f730ee61e1)
- KiKit no longer crashes when the resulting copperfill is empty (28689dfad1b95ecc23b520ed1e6a5f7ffe1327c3)
- DRC rule `footprint_type_mismatch` is not correctly handled (96a964693265d3330ca10c8ce07d10520cde626b)
- References are now correctly oriented in v8 (495e55c051bb5cb97a580f73d0a5422af7349a74)
- KiKit GUI is now compatible with v8 (077c8abc105febb7d9e872d6aa4868a6c90f3f3b)
- When running on v8, the pcbnewTransition module should no longer break compatibility with other plugins (21c74e1ae737422bdfd9a30b2bbc3bf8caa43ad3)
- the odd-even column placement was fixed (thanks errno) (49363ea96f1c1e2947aa3b0125487e35c7311a6b)
- overall documentation improvements (b4188f280f7c09c46100d5714d2370b5a94b2198, 7a3ae3451850ad219072514894983ccb1cb83aaa)

How to upgrade

Simply [update the Python package](https://yaqwsx.github.io/KiKit/v1.5/installation/upgrading/). There is no need to update the PCM package.

This release ships mainly with KiCAD 8 support, bug fixes, and a couple of new features. Note that this release drops support for KiCAD v6.

New features
- KiCAD 8 support
- Shapely 2 support to support new Linux distributions (3427a8d6ce31eea6fb3647e550d6b4ddc0e90842)

- new internal organization of panel features that uncouples panel from features. It should improve plugin support and make the code more extendable.
- the copper fill was already migrated to this new interface
- hex copper fill (c3a8dd0be2754a15fc864f88ec9aab5479f8efda)
- splitting the copper fill into small islands to prevent panel warping during reflow
- you can specify layers by their number, not only by name (b0c1db8716b0e7af5fa0d8c95fcbc750d5fb1c75)
- OpenPnP fab command was added (db1861574d7f43a055271b895a826c4234007b2b)

How to upgrade
Simply [update the Python package](https://yaqwsx.github.io/KiKit/v1.4/installation/upgrading/). There is no need to update the PCM package. Note that if you are using the official Linux debian packages, you have to use the testing repository at the moment, [as the initial release missed scripting support.](https://gitlab.com/kicad/packaging/kicad-ubuntu-builder/kicad-daily-package/-/issues/52)

This release brings:
- compatibility with KiCAD 7,
- new documentation pages,
- several new features and
- bug fixes.

Compatibility with KiCAD 7

New major release of KiCAD 7 was published. This release brought many incompatibilities, but all should be resolved, and KiKit is compatible with both, KiCAD 6 and KiCAD 7.

The new "In BOM" and"Do not place" options in KiCAD schematics are now supported for the `fab` command.

Getting everything right for v7 took a little longer than anticipated, and we didn't manage to meet this release with the release of KiCAD.

New documentation pages

We used to keep documentation in Markdown files in the repository. We now provide a documentation build as an interactive webpage available at [https://yaqwsx.github.io/KiKit/](https://yaqwsx.github.io/KiKit/). This documentation is also available for various released versions, so there should be no confusion between stable release and upstream documentation in the future. New system will also allow us to style the documentation better (e.g., checkout the new [Examples section](https://yaqwsx.github.io/KiKit/v1.3/panelization/examples/)). There's definitely still a lot to improve, but the first step has been made.

New features

- we now support asymetrical frame chamfers. Therefore, you are no longer limited to 45°, but you can choose any angle you want.
- we also added a new option, `dimensions`, to the `post` section that will render dimensions objects showing the overall size of the panel.
- there were multiple feature requests for supporting filleting of tabs natively without milling simulation. This was implemented as two options:
- there is a new `post` option `millradiusouter` which simulates the milling only on the outside edges of PCB and leaves any internal features intact.
- there is a new option, `fillet` for tabs that will add natural chamfering without milling simulation. However, the feature is relatively slow and can increase panel building times by 20–50 %. There are plans for speeding this up, but it will require a complete rewrite of the geometrical part of KiKit.
- fiducials can now be propagated to stencil, so they are visible for alignment.
- the corner patches in full-width tabs are now optional, which allows the usage of full-width tabs with rounded corners.
- the corner tabs used to point into the middle of PCB. This created distorted tabs on narrow PCBs. We now always place the corner tabs at 45°.
- when using `boneskip` parameter to skip backbones we now added `vbonefirst` and `hbonefirst` parameters to specify the offset of skipping (e.g., start at even or odd backbone).
- the graphical interface of show/hide references was reworked. We now also allow for hiding/showing any text items that contain value of reference.
- we added deduplication of mouse bite cuts. When two cuts should be laid one over, duplicate holes are no longer produced.
- a time variables (e.g., hours, minutes, day, month) were added to the text options.

Bugs

- big with Windows encoding was fixed
- a incompatibility with Interactive HTML BOM was fixed
- V-cuts keepouts are only placed on actually used copper layers
- macOS installation script was fixed
- bug in the placement of non-orthogonal tabs was fixed
- a fall-through of argument in the `fab` command was fix

Misc

- we now provide two flavors of the Docker image: one for v6 and one for v7
- the Docker image now features KiKit as entry point, which allows for simple wrapping of the docker container for issuing commands (see [documentation](https://yaqwsx.github.io/KiKit/v1.3/installation/docker/))

How to upgrade

Simply [update the Python package](https://yaqwsx.github.io/KiKit/v1.3/installation/upgrading/). There is no need to update the PCM package.

This release brings several bug fixes and small improvements in functionality.

Bugfixes:
- not all layers were considered when using `all` in the layer selector
- user layers were added to the layer selector
- V-cut copper clearance wasn't applied to internal layers
- GUI sections are now properly shown/hidden after importing JSON configuration

New features:
- you can now specify fillet radius for tabs. Therefore, you can achieve a rounded board-tab interface without milling simulation.
- panel can now be positioned via a percentage of the page width. Therefore, you can, e.g., specify `50%` to place the panel in the middle of the page.
- with regards to the previous change, the separate command now behaves in agreement with its docstring, i.e., it places the separated board in the middle of the page.

This release brings several bugfixes:
- KiKit no longer crashes on projects without an absolute path
- formatting string `{time24}` was fixed
- several documentation strings were made more accurate
- a bug in arc reconstruction was fixed
- component placement files never output more than two decimal places as more places are not accepted by most fab houses
- we removed dependency on `zip` executable (so all commands now work well on Windows)
- KiKit can correctly handle schematic sub-sheets that used to be top-level sheets.

With these bugfixes the following options were added:
- `--debug` flag for the fab command
- we added an option to disable arc reconstruction in a separate command.

All users are encouraged to upgrade.
