--- layout: default title: Upgrading from 2.1 to 2.2 description: Guide to upgrading to newer versions of this library --- # Upgrading from 2.1 to 2.2 ## Deprecation of `MarkdownConverterInterface` The `MarkdownConverterInterface` and its `convertToHtml()` method were deprecated in 2.2.0 and will be removed in 3.0.0. You should switch your implementations to use `ConverterInterface` and `convert()` instead which provide the same behavior.
