The OneAgent release notes for version 1.209, published on February 10, 2020, detail several updates and changes, including the deprecation of the no_create installation parameter, which now defaults to the LocalSystem parameter for new installations. The release also signals upcoming removals of deprecated installation parameters in version 1.213, urging users to replace them with the equivalent --set-param=<value> parameters. This version introduces support for the Confluent Kafka client library 1.4.0+ for .NET and .NET Core, and announces the last version for supporting certain OpenTelemetry versions for Go and Node.js. Future changes include a phased discontinuation of support for several operating systems starting in 2026. The 1.209 release resolves 33 issues across various components, including vulnerabilities and improvements in detection and configuration, such as Apache command line argument corrections and enhanced handling of the OneAgent .NET code module. Cumulative updates address additional issues, including those related to the mainframe, Go, .NET, and Java components, as well as enhancements for mobile agents on iOS and Android.
