# This workflow includes attachments specific after a new version tag is pushed in the main repository.
# On 2026-01-23, this is not something that exists in the actual examples repository, but it is prepared for future use.
# This is also done to validate the implementation proposed in https://github.com/maxGraph/maxGraph/pull/996 which could serve as a model for other repositories.
