 When you start to evaluate trends, be aware of events from the past that may invite comparisons with history. Here are a few to keep in mind:
 
-- **Feb 29 , 2024** - Spike in the [search engine changed probe](https://dictionary.telemetry.mozilla.org/apps/firefox_desktop/metrics/search_engine_default_changed) for users who had an engine update for versions 124 and up . This is due to search.engine.default.changed probes being triggered during engine updates even when users don't actually change their default search engines post-update [bug](https://bugzilla.mozilla.org/show_bug.cgi?id=1876178). More details can be found [here](https://mozilla-hub.atlassian.net/browse/RS-1051)

 - **Dec 7, 2023** - Contextual Services data for Firefox Desktop versions 116 and up [now supplied by Glean](http://mozilla-hub.atlassian.net/browse/DSRE-1489).
 - **Nov 20, 2023** - Changeover day for Onboarding data sent via Messaging System from PingCentre to Glean. Views and datasets downstream of `messaging_system.onboarding` [began being fueled by Glean-sent data instead of PingCentre-sent data](https://github.com/mozilla/bigquery-etl/pull/4457).
 - **Jul 16, 2023 - Jul 24, 2023** - During the migration from release to ESR of Firefox users on obsolete versions of MacOS and Windows, Firefox sent deletion request pings for clients in the migration, which also reset the `client_id`. [See the summary of the incident here.](https://docs.google.com/document/d/1vdn9OFSoKPD5wt14dmTwyh0kGs-96fWx26ESui95jo0/edit). Approximately 2 million clients were affected by this bug; as a result of this, around 1.3 million clients were double counted due to both the old `client_id` and reset `client_id` being active on the same day.
