Worked on updating documentation for MicrosoftDocs/defender-docs, specifically delivering the Linux Defender for Endpoint Release Notes Update for build 101.25042.0003. Focused on ensuring that linux-whatsnew.md accurately reflected the latest release version, rollout schedule, and stability improvements, aligning documentation with the current software state. Emphasized traceability by maintaining clear commit references and repository linkage throughout the process. Utilized Markdown for precise documentation updates and applied strong attention to detail to support release readiness. The work improved customer clarity and reduced support inquiries by making release information more accessible, ultimately supporting faster adoption of the new Linux Defender release.
