Experimental v0.49.0

0.49.0

💥 Breaking Change

• fix(otlp-exporter-base)!: remove unload event from OTLPExporterBrowserBase #4438 @eldavojohn
  • Reason: The 'unload' event prevents sites from taking advantage of Google's backward/forward cache and will be deprecated. It is now up to the consuming site to implement these shutdown events.
  • This breaking change affects users under this scenario:
    1. A user extends the exporter and overrides the shutdown function, and does something which is usually called by the unload listener
    2. We remove the unload event listener
    3. That user's overridden shutdown function no longer gets called
