OneAgent version 1.249 introduces several new features and enhancements, including the detection of Milan and Jakarta AWS regions as EC2 cloud types and the auto-instrumentation of SwiftUI controls for iOS 8.249. It adds support for OpenTelemetry versions 1.8-1.11.0 and the Golang toolchain 1.19, along with Amazon Linux 2023 and Rocky Linux 9. This release is notable for being the last to support certain technologies like JBoss Enterprise Application Platform 6 for Java, which has been de-supported since 2019. Future support changes include the discontinuation of various operating systems, such as Amazon Linux 2023 and Windows Server 2012 R2, by mid-2026. The release also resolves a range of issues across components such as .NET, PHP, and JavaScript, enhancing stability and security, including improved input validation for Real User Monitoring (RUM). Additionally, cumulative updates address several vulnerabilities and technical glitches, contributing to a more robust and secure platform.
