## LEGAL BOILERPLATE

<!-- Sentry employees and contractors can delete or ignore this section.
-->

Look, I get it. The entity doing business as "Sentry" was incorporated
in the State of Delaware in 2015 as Functional Software, Inc. and is
gonna need some rights from me in order to utilize my contributions in
this here PR. So here's the deal: I retain all rights, title and
interest in and to my contributions, and by keeping this boilerplate
intact I confirm that Sentry can use, modify, copy, and redistribute my
contributions, under Sentry's choice of terms.

 ### How does this relate to the stability of a feature?
 
 A `Stable` release status doesn't guarantee the stability of an SDK feature or product feature. A new feature that's still experimental might be part of a stable SDK release. Any experimental features will be clearly marked and offered as an opt-in.
