🛑 Breaking changes 🛑

  • exporter/debug: Disable sampling by default (#9921) To restore the behavior that was previously the default, set sampling_thereafter to 500.

💡 Enhancements 💡

  • cmd/builder: Allow setting otelcol.CollectorSettings.ResolverSettings.DefaultScheme via the builder's conf_resolver.default_uri_scheme configuration option (#10296)

  • mdatagen: add support for optional internal metrics (#10316)

  • otelcol/expandconverter: Add confmap.unifyEnvVarExpansion feature gate to allow enabling Collector/Configuration SIG environment variable expansion rules. (#10391) When enabled, this feature gate will:

  • confmap: Add confmap.unifyEnvVarExpansion feature gate to allow enabling Collector/Configuration SIG environment variable expansion rules. (#10259) When enabled, this feature gate will:

  • confighttp: Allow the compression list to be overridden (#10295) Allows Collector administrators to control which compression algorithms to enable for HTTP-based receivers.

  • configgrpc: Revert the zstd compression for gRPC to the third-party library we were using previously. (#10394) We switched back to our compression logic for zstd when a CVE was found on the third-party library we were using. Now that the third-party library has been fixed, we can revert to that one. For end-users, this has no practical effect. The reproducers for the CVE were tested against this patch, confirming we are not reintroducing the bugs.

  • confmap: Adds alpha confmap.strictlyTypedInput feature gate that enables strict type checks during configuration resolution (#9532) When enabled, the configuration resolution system will:

    • Stop doing most kinds of implicit type casting when resolving configuration values
    • Use the original string representation of configuration values if the ${} syntax is used in inline position

  • confighttp: Use confighttp.ServerConfig as part of zpagesextension. See [https://github.com/open-telemetry/opentelemetry-collector/blob/main/config/confighttp/README.md#server-configuration](server configuration) options. (#9368)

🧰 Bug fixes 🧰

  • exporterhelper: Fix potential deadlock in the batch sender (#10315)
  • expandconverter: Fix bug where an warning was logged incorrectly. (#10392)
  • exporterhelper: Fix a bug when the retry and timeout logic was not applied with enabled batching. (#10166)
  • exporterhelper: Fix a bug where an unstarted batch_sender exporter hangs on shutdown (#10306)
  • exporterhelper: Fix small batch due to unfavorable goroutine scheduling in batch sender (#9952)
  • confmap: Fix issue where structs with only yaml tags were not marshaled correctly. (#10282)
