Make it easier to subclass the wikitext parser with a custom rule set

Browse Source 
We can now pass arrays of rule classes to the parser constructor, overriding the rules that would normally be used by the parser.

This allows us to create custom variants of the wikitext parser with their own content type.

It could also provide a basis for a new Markdown parser based on our existing wikitext parser but with new rules.
