- The GUI was optimized (03edf1fe528dfee8600d9896572ebfec1913abc9)

How to update
- upgrade KiKit backend (see https://yaqwsx.github.io/KiKit/latest/installation/upgrading/)
- upgrade the symbols and footprint library via PCM
- there is no need to update the PCM plugin

New features

- In case of error, KiKit tries to build the panel and places error annotation into a board with the suffix `.failed.kicad_pcb`. In that way, the user can easily spot where and which error happens (d1bbcdfeba1664d8c6defcff98b8725006c6967d)
- The GUI used to be pretty limited in features it supports, e.g., you couldn't set page size due to limitations in KiCAD API. This wasn't very clear for many users. The user must now specify an output file in the GUI where the panel is saved. The PcbNew window is just used for the panel preview (8aca5bf3a1b471775d4d0327435d7dd15cb7a5f2).
- There are new parameters you can customize for V-cuts such as text position, size, etc. (a0c1e445b201e602a1355ba55e4b7b1ec6ffec1a, 2e25a3d595683c32ac4e2007ba85baabc734faed)

Bug fixes

- compatibility with KiCAD 8.0.4 on Windows was ensured.
- text on bottom layer not being mirrored on Windows was fixed (0de661c7033c4d6bba450c1f60dd02f26f1426df)
- outdated dependencies were updated (e0c312ae105c8d2a4626b83ac86324b1a1be75ba, eac56affe51dc7c99e426bc7b02e88b5e1d8b115)
- accommodate for some numerical instabilities (69bcf0bb045e9503eaf58ea705a44de4d07cde6b, 28409eb527ad9efed1f3854ffcd973b3eadbfd3b, acbd02139019f22d97de78cc494898566ca036e9, a7873c203fd7b1e274d4739c12809f652da4ac89)
- error reporting was improved (3636a3e75b21acdeed25cafcf5b6199076aa0b7f, 32187adc453f9c9ed7100ea9c5e3dbe301f7d3c1)

How to update

- upgrade KiKit backend (see https://yaqwsx.github.io/KiKit/latest/installation/upgrading/)
- upgrade the symbols and footprint library via PCM

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

- 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

- 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)
