This successful release was also a major milestone for Parsoid (the parsing program that translates plain wikitext into HTML annotated for easy editing, and vice-versa). Parsoid needs to handle the full range of arbitrary and complex existing wiki content, including templates, tables and extensions; it did so very well, as witnessed by the lack of mistakes introduced by Parsoid in the wikitext. This was in large part due to the team's efforts on automated conversion testing and the completion of a strategy to only convert the parts of the page what were edited ("selective serialization").
