🛑 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:
  • Disable expansion of BASH-style env vars ($FOO)
  • ${FOO} will be expanded as if it was `${env:FOO} See https://github.com/open-telemetry/opentelemetry-collector/blob/main/docs/rfcs/env-vars.md for more details.
• confmap: Add confmap.unifyEnvVarExpansion feature gate to allow enabling Collector/Configuration SIG environment variable expansion rules. (#​10259) When enabled, this feature gate will:
  • Disable expansion of BASH-style env vars ($FOO)
  • ${FOO} will be expanded as if it was `${env:FOO} See https://github.com/open-telemetry/opentelemetry-collector/blob/main/docs/rfcs/env-vars.md for more details.
• 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 options. (#​9368)
