🛑 Breaking changes 🛑

  • This version adopts OpenTelemetry Core version 0.42.0, and in doing so the configuration parsing process has changed slightly. The Splunk OpenTelemetry Collector used to evaluate user configuration twice and this required escaping desired $ literals with an additional $ character to prevent unwanted environment variable expansion. This version no longer doubly evaluates configuration so any $$ instances in your configuration as a workaround should be updated to $. Config source directives that include an additional $ are provided with a temporary, backward-compatible $${config_source:value} and $$config_source:value parsing rule controlled by SPLUNK_DOUBLE_DOLLAR_CONFIG_SOURCE_COMPATIBLE environment variable (default "true") to migrate them to single $ usage to continue supporting the updating configs from #930 and #935. This functionality will be removed in a future release (#1099)

🚀 New components 🚀

💡 Enhancements 💡

🧰 Bug fixes 🧰
