Apr 1, 2026In April 2026, focused on strengthening security posture and reliability for elastic/logstash by applying a targeted dependency patch to Log4j. The Log4j version was upgraded from 2.25.3 to 2.25.4 to address potential vulnerabilities and improve logging reliability. The change is captured in commit ce7ef0282b74bda648cf88738774957e1513fb81 with message 'log4j update to 2.25.4 (#18991)'. This maintenance fix reduces exposure to known CVEs, preserves log integrity, and maintains deployment stability. No new features were added this month; the work emphasizes security hygiene and risk reduction across critical logging pipelines.
