This comes a bit late, but for those who use python plugins:
Because of KiCad code API changes v5 plugins don’t necessarily work with 5.99 (or later v6). It depends on each plugin developer how they handle this. For example Interactive HTML BOM by @qu1ck has been updated in git master but some other plugins don’t work as of now.
The plugin search path has changed. The safest way to add plugins for 5.99 is probably to use
<user configuration dir>/scripting/plugins/, i.e.
~/Library/Preferences/kicad/5.99/scripting/plugins/on Mac (untested by me).
(EDIT: see Post-v5 new features and development news below)
- Python console may not work, see [SOLVED] Kicad Nightly "unable to create the Python console" etc. (Maybe I should recompile KiCad from scratch because this still doesn’t work automatically for me. EDIT: yes, rebuilding from scratch works.)
Qu1ck has also added some helpful buttons into the plugins Preferences section, see https://gitlab.com/kicad/code/kicad/-/merge_requests/561.
