In DevelopmentKind: in v2.1.242,
In DevelopmentSection of the release
Unlike its neighbours, the sandboxed-attempt slot has no flag name or accessors attached.
What
The declaration of that sandboxed-attempt slot is its only occurrence in the build. Its neighbours all follow a fixed pattern, either filled lazily from a named remote flag with an on-by-default fallback or given an explicit setter and getter; this one has none of that, and no flag name is attached to it.
Details
Nothing assigns it and nothing reads it, so no behaviour depends on it in this build.
