I use my own function extention that return wikitext containing templates link "{{ | }}" 
It used to work in 1.11 : the link was parsed and replaced, but with new parser it just show the template code.
It still work with standard links : [[ ]] but no more with templates ones {{ | }}

now using 1.13-svn but did not work in release 1.12.0

did I missed something, or is that a real bug...?

Thank you.
