EDIT: continue using Launchpad as long as it’s available.
The whole KiCad ecosystem will be moved to gitlab. Wayne just announced that bug reports and the reporting system are being migrated right now. It may cause some inconvenience, very soon you may not be able to report bugs for some time (hopefully only hours, not days - let’s see).
Wayne also said: “Please do not file any new bugs on GitLab until I make the announcement
that the migration is complete.”
Bugs which have been fixed are already visible in the new bug database. If I have understood correctly only relatively new fixed bugs are moved, older ones (like fixed in v4.0) won’t be there.
So, when launchpad reporting is disabled you may need to wait a bit before trying to write your next bug report! Right now the lauchpad tracker is still functional, though.
