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.
