During February 2026, Ozel Alisen focused on stabilizing CloudFormation intrinsic token handling in Java within the phuhung273/aws-cdk repository. Addressing a runtime bug, Ozel resolved issues with intrinsic CloudFormation function tokens, reducing potential errors for Java users and releasing the fix in version 2.237.1. Alongside this, Ozel improved project documentation by correcting Markdown changelog headings, enhancing clarity and onboarding for new contributors. The work involved skills in bug fixing, release management, and version control, utilizing JSON and Markdown. While the period did not include new feature development, the targeted improvements contributed to greater project stability and maintainability.
