Upgrading

Cucumber tries to follow the SemVer specification for release numbers. Essentially, that means that:

• If only the right-hand (patch) number in the release changes, you don't need to worry.
• If the middle number (minor) number in the release changes, you don't need to worry.
• If the left-hand (major) number changes, you can expect that things might break.

You can read the history file to learn about the changes in every release: https://github.com/cucumber/cucumber/blob/master/History.md
