We’re moving over to a newer parser/renderer library for markdown texts (https://github.com/vsch/flexmark-java), because of performance issues with the one currently used (https://github.com/sirthias/pegdown).

Unfortunately, it’s hard to exactly match the parsing behavior of pegdown. After analyzing and fixing most of the common problems found while migrating to the new library, most pages will render the same HTML. However, it’s possible that some changes in rendering are missed by the analysis. Most issues are related to mixed use of HTML and markdown, and blank lines after HTML blocks.
