How do you use Sentry?

Sentry Saas (sentry.io)

Version

2.38

Steps to Reproduce

1. Use add_breadcrumb() and set_tags() in your code.
2. Using 2.20.0, emit events and see that Breadcrumbs and custom tags are present
3. Upgrade to 2.38.0, emit events and see that Breadcrumbs are missing and only basic tags are present

Expected Result

Breadcrumbs and custom tags should still be present in events using newer versions of the API

Actual Result

No breadcrumbs or custom tags are present.

Attached are screenshots of the tags before and after. The before are from a day before the upgrade, the after are from ~8 hours after the upgrade. The sentry configuration didn't change during that time.
