v52.0.0

Full changelog

• General
  • Remove the metric glean.validation.first_run_hour. Note that this will mean no reason=upgrade metrics pings from freshly installed clients anymore. (#2271)
  • BEHAVIOUR CHANGE: Events in Custom Pings no longer trigger their submission. (bug 1716725)
    • Custom Pings with unsent events will no longer be sent at startup with reason startup.
    • glean.restarted events will be included in Custom Pings with other events to rationalize event timestamps across restarts.
  • test_reset_glean will remove all previous data if asked to clear stores, even if Glean never has been initialized (#2294)
  • Upgrade to glean_parser v6.5.0, with support for Cow in Rust code (#2300)
  • API REMOVED: The deprecated-since-v38 event metric record(map) API has been removed (bug 1802550)
  • BEHAVIOUR CHANGE: "events" pings will no longer be sent if they have metrics but no events (bug 1803513)
  • Experimental: Add functionality necessary to remotely configure the metric disabled property (bug 1798919)
    • This change has no effect when the API is not used and is transparent to consumers. The API is currently experimental because it is not stable and may change.
• Rust
  • Static labels for labeled metrics are now Cow<'static, str> to reduce heap allocations (#2272)
  • NEW INTERNAL CONFIGURATION OPTION: trim_data_to_registered_pings will trim event storage to just the registered pings. Consult with the Glean Team before using. (bug 1804915)
