Worked on the teemtee/tmt repository to enhance deployment reliability and documentation clarity. Delivered two features, focusing on operating system compatibility and release engineering. Updated the Ansible playbook to support EPEL-10 by refining version checks and enabling EPEL and EPEL-Next repositories for RHEL 8+ and CentOS Stream 8+, ensuring alignment with the latest EPEL-10 release. Improved release documentation for version 1.43.0 by detailing new features such as plan splitting by maximum test count and logging test names in the kernel buffer for dmesg checks. Utilized Ansible, YAML, and reStructuredText, emphasizing system administration and technical documentation.
