Run expiration changes in Spacelift
An unconfirmed run doesn't just disappear from existence. It sits there in Spacelift, waiting on a response, until someone remembers to deal with it. These can stack up and leave your run list pretty crowded. We just introduced a quality of life improvement for you.
Starting today, any run that doesn't reach a final state within 30 days of creation will expire and be removed from the queue, including runs that are simply waiting for approval or confirmation. Be sure to check the Runs to be Terminated widget on your Dashboard to see which runs will be expired within the next 7 days:

Finished runs and your existing infrastructure will not be affected in any way. If there's a run you still need, make sure it is approved, confirmed, or finished in some way before it hits the 30 day mark.
