# Bleeding edge 🔪

- Analysis with zero files results in non-zero exit code
(phpstan/phpstan-src@46ff440),
[#&#8203;9410](https://togithub.com/phpstan/phpstan/issues/9410)

*If you want to see the shape of things to come and adopt bleeding edge
features early, you can include this config file in your project's
`phpstan.neon`:*

    includes:
    	- vendor/phpstan/phpstan/conf/bleedingEdge.neon

*Of course, there are no backwards compatibility guarantees when you
include this file. The behaviour and reported errors can change in minor
versions with this file included. [Learn
