The comment describes this as "Archived Backups" but based on the KiCad forum discussion linked in the PR, the .history folder is for internal history tracking, not archived backups. Consider updating the comment to more accurately describe this feature, such as "Internal history folder (KiCad 10.0)" or "History tracking folder (KiCad 10.0)".

Suggested change

	# Archived Backups (KiCad 10.0)
	# Internal history folder (KiCad 10.0)

The pattern .history/ will only match a .history folder at the repository root level. If .history folders can exist in subdirectories (e.g., within project subfolders), this pattern should be **/.history/ to match at any directory level, consistent with the pattern used for KiCad 6.0 backups above (**/*-backups/*.zip).

Suggested change

	.history/
	**/.history/
