New features and enhancements
The OneAgent installer now requires a minimum glibc version of 2.12. Attempting to install OneAgent on systems with glibc version 2.5 or lower will result in an error message and halt the installation process. If you encounter the error message below, upgrade your operating system to a version that supports glibc 2.12 or higher.
Error: We can't continue setup. The glibc version: 2.5 detected on your system isn't supported.
z/OS modules download

Resolved issues
General Availability (Build version_1.275.146)
The version_1.275 GA release contains 13 resolved issues (including 1 vulnerability resolution).
Java
- Fixed instrumentation code for CTG communication. (OA-20873)
General
- Fixed compatibility with musl-libc builds that don't contain LFS function exports with a "64" suffix. (OA-20428)
- The NGINX module no longer removes the content-length HTTP header for applications whose content-type does not end with "/xml:xml" or "/json:json". (OA-19190)
PHP
- Fixed handling of cross-environment tracing headers in the PHP Curl code module for missing resource close calls (PHP 8.0+). (OA-19119)
OS module
- Vulnerability: Improved security by updating the aiohttp package to version 3.8.5. (HOST-3456)
- Disabling all OS service monitoring rules in the web UI now correctly stops monitoring of OS services. (HOST-3641)
.NET
- Improved cookie handling for Real User Monitoring (RUM) for ASP.NET Core. (OA-19432)
- Improved compatibility of Real User Monitoring (RUM) for ASP.NET Core and .NET Business Events. (OA-20161)
Mainframe
- Corrected z/OS batch CICS Transaction Gateway jobname, which was showing INIT as jobname. (OA-19454)
OneAgent Installer
- The OneAgent installer now tries to install the SELinux module 3 times in case of failure. (DMX-4061)
- If installation of the SELinux module fails, OneAgent installation is now canceled, and the installer exits with a non-zero exit code. As a result, the OneAgent container exits as well, blocking Kubernetes rollout. (DMX-4841)
OneAgent SDK for C/C++
- Improved handling of large numbers of custom service tracers. SDK users should create custom service tracers only in cases where the custom service is actually a relevant part of the monitored application that needs to be visible separately. When a high number of custom service tracers is created in a single trace, it's usually a sign of over-monitoring, and SDK users should reduce the number of tracers they manually create (for example, only trace the outermost call, not less relevant method calls). However, OneAgent now attempts to improve efficiency by aggregating repeated custom service tracers together when it detects a high number of them. (OA-19444)
Go
- Fixed possible crash during Go code module initialization if the "Go software component reporting" feature is enabled. (OA-20012)
