legacy.toml

The legacy.toml file is used to opt-out of certain breaking changes in Easel. It is intended as a temporary measure to allow you to upgrade to the latest version of Easel without having to update all aspects of your code at once. You may choose to skip over certain breaking changes until you have time to update your code, but you should always eventually aim to support the latest version of Easel fully with no opt-outs.

The upgrade instructions for each edition lists the legacy.toml parameters that can be used to opt-out of the breaking changes in that edition, if any. See the List of Editions for more information.
