💡 Enhancements 💡

• (Splunk) Splunk_TA_otel: Change internal/settings log format for Splunk TA for OpenTelemetry (#6749)
  The formatting of the internal/settings log was changed to correctly report log level when the collector is running
  as the Splunk TA for OpenTelemetry. Related to change #6748.
• (Splunk) fips: Use native FIPS 140-3 support, bundled with go 1.24 (#6718)
  See FIPS 140-3 Compliance.
• (Splunk) installer: The Windows MSI installer now supports setting the GODEBUG environment variable. (#6719)
  You can set GODEBUG to turn on Go runtime FIPS 140-3 compatibility with the following values:
  • GODEBUG=fips140=off turn off any FIPS 140-3
  • GODEBUG=fips140=on turn on FIPS 140-3. This is the preferred setting in FedRAMP environments.
  • GODEBUG=fips140=only Experimental mode to disable any encryption mechanisms but FIPS 140-3 encryption.
    This mode is still under review by the Go team.
    See FIPS 140-3 Compliance for further information.
• (Splunk) installer: Expose setting GODEBUG as an option of the install scripts (#6778)
• (Splunk) discovery: Automatic discovery of RabbitMQ by default enables the extra metrics used by dashboards on Splunk Observability (#6509)
