In August 2025, delivered Dockerfile naming convention support in Hadolint for purpose.Dockerfile in the oxsecurity/megalinter repository. This enhancement broadens lint coverage to Dockerfiles named using the purpose.* convention (e.g., service.Dockerfile), by updating the name-matching regex, and accompanying tests and documentation. The change was implemented in commit 438886d880a1ce2c17015b054d39a425a1e64150. Outcome: improved detection of misnamed or variant Dockerfiles, leading to more consistent security linting across multi-service projects.
