Added automatic Real User Monitoring (RUM) injection for ASP.NET Core applications running on a Kestrel web server. To enable this as a OneAgent feature
Go to Settings > Server-side service monitoring > Deep monitoring.
Expand the New OneAgent features section, find Enable Real User Monitoring (RUM) for ASP.NET Core, and turn it on.
Starting with OneAgent for Android version 8.245, we're ending support for the following versions of Android and Gradle plugin:

New features and enhancements
Installer
On Windows, usage of legacy dtuser will be implicitly converted to Local System account during update.
Log Monitoring
The OneAgent log module is able to extract attributes from log content and enrich log records. The OneAgent log module now processes the enriched log data, improving performance. For details, see Connecting log data to traces (Logs Classic).
OneAgent watchdog
Two new parameters were introduced (currently used only in OneAgent Linux installation):
coredump.non_root_use_sigquit
If set and watchdog is started with a non-root user (uid != 0), watchdog sends SIGQUIT signal to child process in case of ping timeout, memory exceeded, or shutdown timeout to trigger a core dump. Default: false
non_root_drop_capabilities
If set and watchdog is started with a non-root user (uid != 0), watchdog drops all capabilities after initialization (before starting any child processes) and marks its own process as dumpable (prctl(PR_SET_DUMPABLE, 1)). Default: false
Improved stability of the OneAgent .NET module in Infrastructure Mode. (ONE-74546)
IIB
Added troubleshooting agent options to disable the writing Dynatrace trace tags for Java (via JavaCompute node) and .NET (via DotNetComputeNode) to folder "LocalEnvironment.Variables.Dynatrace", introduced in 1.229. (ONE-74722)

Corrected issue in which, in rare circumstances, incorrect values were assigned to Kubernetes properties such as pod name, container name, or namespace. (ONE-72282)
Cluster
Corrected issue with reverse DNS lookup. (EXT-59)
General

Infrastructure Monitoring
Data source now sends collected metrics more frequently to resolve an issue with gaps in charts. (EXT-97)
StatsD data source now prints collected self-monitoring metrics to the log on process exit. (APM-360169)
Fixed rare issue where EEC would report incorrect extremely high CPU usage after restarting datasource due to high CPU. (APM-360930)
Logging module
Renamed config options responsible for severity detection to `LAConfigSeverityDetectionLimit_Bytes` and `LAConfigSeverityDetectionLinesLimit`. (APM-356991)
Mainframe
Subagents are registered with zRemote version again. This fixes deactivation of the zAgent if an outdated subagent is trying to connect. (ONE-75119)
OS module
OneAgent OS module now properly reports host memory metrics, even if CONFIG_VM_EVENT_COUNTERS is disabled in Linux kernel configuration. (APM-360172)
.NET
Log enrichment for MS extension logging no longer leads to index-out-of-range exceptions, and correct prefixes are now used. (ONE-73433)
PHP
Added additional data capturing when redis call method fails. (ONE-74172)

OneAgent Installer
Resolved issue in which installer was stuck when trying to disable abrt-ccpp service that does not exist on SLES systems. (APM-362992)
Update 292 (Build 1.239.292)
This cumulative update contains 5 resolved issues and all previously released updates for the 1.239 release.
Fixed log enrichment for Apache webserver in case of virtual host usage. (ONE-75479)
All modules
For the Kubernetes workload detection rule feature, the process group name and ID calculation have been fixed: (1) Process group name: When a Kubernetes workload detection rule is applied, a meaningful name for the process group is created from the rule. (2) Process group ID: A Kubernetes workload detection rule is applied even if ID-relevant fields are missing but at least one is present. (ONE-74933)
Mainframe
Subagents are registered with zRemote version again. This fixes deactivation of the zAgent if an outdated subagent is trying to connect. (ONE-75119)
