v30.1.0

• Android & iOS
  • Ping payloads are now compressed using gzip.
• iOS
  • Glean.initialize is now a no-op if called from an embedded extension. This means that Glean will only run in the base application process in order to prevent extensions from behaving like separate applications with different client ids from the base application. Applications are responsible for ensuring that extension metrics are only collected within the base application.
• Python
  • lifetime: application metrics are now cleared after the Glean-owned pings are sent,
    after the product starts.
  • Glean Python bindings now build in a native Windows environment.
  • BUGFIX: MemoryDistributionMetric now parses correctly in metrics.yaml files.
  • BUGFIX: Glean will no longer crash if run as part of another library's coverage testing.
