Review new post conditions and audit project scripts

New post conditions

The changed condition has always been a bit confusing, and to be honest, it wasn’t our best work. changed will fire any time the current run’s status is different than the previous run’s status - whether the current run is healthier than the previous one, or the other way around. That’s…not actually very useful. So now we’ve added two new post conditions that should provide you with a lot more value than changed has.

• fixed - This will check to see if the current run is successful, and if the previous run was either failed or unstable.
• regression - This will check to see if the current run’s status is worse than the previous run’s status. So if the previous run was successful, and the current run is unstable, this will fire and its block of steps will execute. It will also run if the previous run was unstable, and the current run is a failure, etc.
