Nightly Builds

Daily snapshots of the current development status in the master branch provide the bleeding-edge version of Crystal.

Nightly builds are inherently less stable than proper releases. But they allow trying out new features and ensuring compatibility for existing code bases.

It’s recommended to test against nightlies regularly in order to notice any issues ahead of time and avoid surprises with the next release.
