Olli worked on the apache/sling-site repository, focusing on improving release readiness and testing reliability over a two-month period. He upgraded the PaxExam testing framework and its core dependencies, first aligning them to version 4.1.0 and later to 4.1.2, ensuring compatibility and reducing environment drift in continuous integration. Using XML and Markdown, Olli documented upgrade steps and updated release notes, streamlining future dependency management. His work centered on release management and documentation, maintaining up-to-date test dependencies and improving release hygiene. While no bugs were fixed, the depth of his contributions enhanced the stability and maintainability of the project’s release process.
