Add stalledTimeout option to configure how long it waits before deciding a method or publication is stalled.
If called while there is an active trace, Monti.trackError will send the trace events with the error
Improve checks for why a query is not using the oplog. Many of the checks were out of date with new Meteor versions. We've also added some new checks, including for the reactive publish package.
Add disableClientErrorTracking option to only disable error tracking on the client
Fix possible error when running app tests, and global.window is set using jsdom

Fix error when filtering arrays with null values

2.41.0

March 22, 2021

Add Monti.tracer.redactField(fieldName). Removes the value of these fields from objects before storing them in a trace. By default it filters the password field. Is used for headers from incoming HTTP requests, and parameters passed to methods and pub/sub.
Reduce time spent loading the package in the server by up to 80% (from up to ~1,000ms to 200ms)
Reduce disk usage of package from 25mb to 3mb
Warns when an app uses multiple APM agent packages since they can conflict with each other
Remove internal use of Meteor's HTTP package. Monti APM still instruments it to track outgoing HTTP calls in traces.
Store detail property of Method and pub/sub errors (Thanks @ulion).
Fix sending errors from Internet Explorer 9
Documented Meteor and browser compatibility in readme. We support Meteor 1.4 and newer, and Internet Explorer 9 and newer web browsers.
Add Tracer.stripSensitiveThorough filter. This filter internally uses a list of which fields to not strip instead of which fields to strip, which reduces the consequences of forgetting to update the filter after adding new fields
Update Tracer.stripSensitive to support headers and request bodies for HTTP traces
Increase minimum version for monitoring incoming HTTP requests from Meteor 1.6.1 to Meteor 1.7. As before, HTTP monitoring is automatically disabled when using an older version of Meteor.
Drop compatibility for old beta versions of Meteor's email package. You can still force the beta version by modifying your app's .meteor/packages file to have a ! after the email package's version.
Fix filter examples in readme
