Behat Files

This release introduces a number of breaking changes. We have tried to limit the impact of these on end-users – most are in code that we expect is only referenced internally. There are some unavoidable changes that will affect end-users and extension authors, but we expect you will be able to apply the vast majority of updates using automated tools. See https://docs.behat.org/en/v4.x/releases/upgrading-to-4.0.html for advice on upgrading.

For end-users, this is essentially a stable release, ready to use in your CI. The only reason for shipping as an alpha first is to allow extension authors to add support for Behat 4.x and feed back on any issues before we finalise 4.0.0.

We expect there will be a small number of breaking changes between 4.0.0-alpha1 and 4.0.0. See https://docs.behat.org/en/v4.x/releases/upgrading-to-4.0.html for details.

Behat has no corporate backing - the 4.0 release has taken a huge effort from the volunteer maintainers over the last 9 months. If you use Behat for work, please consider showing your appreciation by supporting the project - even small contributions make a big difference.
