I think I should say a word or two about this: We've decided to switch to
Jinja 2 now because Jinja 1 won't be maintained for much longer.
As said in the changelog, there aren't many syntactical changes, on of them
being the one above -- macro definitions requiring an argument. Jinja2 is
also a bit stricter for undefined variables -- accessing an attribute on
an undefined name raises, so you'll have to change e.g.
{% if foo.bar %}
into
{% if foo and foo.bar %}
if the name "foo" is possibly undefined.
If anyone encounters a problem while switching to Jinja2, please ask here,
and we'll resolve it!
cheers,
Georg
