Upgrading from 1.5 to 2.0
Version 2.0 contains lots of changes throughout the library. We’ve split the upgrade guide into three sections to help you better identify the changes that are most relevant to you:
The upgrade guide for consumers is relevant for developers who use this library as-is to perform basic conversion of Markdown to HTML. You might enable some extensions or tweak the configuration settings, but you don’t write your own custom parsers or anything like that. This condensed upgrade guide therefore only covers the most obvious changes that might impact your usage of this library.
If you develop open-source software that uses this library, read the upgrade guide for integrators. It contains all of the information from the Consumer guide above, but with additional details that may be relevant to you.
The upgrade guide for developers is aimed at developers who create custom extensions/parsers/renderers and need to know about all of the under-the-hood changes in 2.x. It is the most comprehensive guide, containing all of the information from the two guides above, and even more details about the under-the-hood changes that likely impact your customizations.
