0.211.0

💥 Breaking Changes

• fix(otlp-exporter-base)!: remove xhr transport #6317 @cjihrig
  • (user-facing) The deprecated XHR-based transport has been removed and replaced with fetch(). This change affects users who relied on XmlHttpRequest instead of fetch() for sending headers with OTLP exports. To maintain compatibility on browsers without a fetch() implementation, include a fetch() polyfill.
• chore(api-logs)!: remove ProxyLoggerProvider export #6322 @david-luna

🚀 Features

• feat(sdk-logs): export event name from ConsoleLogRecordExporter #6310 @aicest

🐛 Bug Fixes

• fix(sdk-logs): allow AnyValue attributes for logs and handle circular references #6210 @david-luna

💥 Breaking Changes

• feat(otlp-exporter-base)!: allow passing an async function to headers option #5994 @pichlermarc
  • In addition to static headers, OTLP exporters now allow passing an async function that returns headers which will be called before each export. See TSDoc for headers in OTLPExporterConfigBase for details.
  • Breaking changes:
    • (user-facing): headers option in all OTLP exporters now accepts a function that returns a Promise<Record<string, string>> in addition to the existing Record<string, string> type.
    • (user-facing): headers in HttpNodeRequestParameters, FetchTransportParameters, and XhrRequestParameters now only accept async functions.
    • (user-facing): headers in OtlpHttpConfiguration now only accepts async functions.
• feat(sdk-logs): remove NoopLogRecordProcessor from exports #6079 @cjihrig
• feat(api-logs): remove ProxyLogger from exports #6082 @cjihrig
• feat(api-logs): remove NOOP_LOGGER_PROVIDER and NoopLoggerProvider from exports #6086 @cjihrig

🚀 Features

• feat(instrumentation): allow error of safeExecuteInTheMiddleAsync to be async #6032 @JPeer264
• feat(opentelemetry-configuration): parse logger provider from config file #5995 @maryliag
• feat(opentelemetry-configuration): parse meter provider from config file #6000 @maryliag
• feat(opentelemetry-configuration): add backup options for certificates and endpoints #6038 @maryliag
• feat(opentelemetry-configuration): add backups for compression, timeout, headers #6058 @JamieDanielson
• feat(opentelemetry-configuration): set attributes from attribute list from env variables #6043 @maryliag

🐛 Bug Fixes

• fix(instrumentation-fetch): Handling null-body-status responses #6037 @m0sa

📚 Documentation

• doc(sdk-logs): document that SimpleLogRecordProcessor is not for production use #6080 @cjihrig

🏠 Internal

🐛 Bug Fixes

• fix(core): avoid leaking Node.js types via unrefTimer() util #5986 @pichlermarc
• fix(core): avoid leaking Node.js types via otperformance #5987 @pichlermarc
  • important: this bug fix may be breaking for certain uses of otperformance
    • otperformance.now() and otperformance.timeOrigin are not affected.
    • the previously used type was incorrect and overly broad, leading to unexpected run-time behavior runtimes that are not Node.js.
    • these problems are now caught on compile-time: if you have been using this API and this change is breaking to you, please consider using your target platform's performance implementation instead.

🏠 Internal

• test(shim-opentracing): add comparison thresholds in flaky assertions #5974 @cjihrig
• test(exporter-jaeger): clean up OTEL_EXPORTER_JAEGER_AGENT_PORT between tests #6003 @cjihrig
• test(sdk-trace-base): ensure environment variables are cleaned up between tests #6011 @cjihrig
• perf(opentelemetry-core): optimize attribute serialization #5866 @43081j
