Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Async Control Flow
Hmm, you are right, the bracket I pointed to is unrelated. I guess the fix is in catchAny, which doesn't catch ThreadKilled. So not it's not rolling the transaction back in case of asynchronous exceptions. My point is that it probably should not rollback even on synchronous exception. BTW the issue is well know, see for example here

Async Control Flow
I see. Do you think rethrowing the original exception is the the right approach in all cases, or only in this case? In the documentation I wrote for the exceptions package, I recommend to let the release block's exceptions take priority, to match base's behavior. Should I recommend the opposite?
