ahoi.
especially for series it would help to limit the execution of the RSS on the local side with a "date from" and a "date to" field.
another way to think about it is an expiry date.
therefore the feed should only be executed if today's date is within the range of "date from" and "date to".
this limits unnecessary requests and could be planned in advance.
if the fields are not set, they should be ignored.
what do you think?
