# Do "exceptions in threads" behavior has changed? I was reading Dominik's excellent book [Nim in Action](https://book.picheta.me/) and I reached the part where he mentions:
> When a thread crashes with an unhandled exception, the application will crash > with it. It doesn't matter whether you read de value of `FlowVar` or not. Down the paragraph he states that: > This behavior will change in a future version of Nim, so that exceptions > aren't raised unless you read the value of the `FlowVar`. I have searched the blog on releases and I haven't found any reference to a solution. May be I missed it or maybe it is solved. Any information about it would be appreciated.
