i don't know i have to update it or not
A feed editor like that will require you to manually update, save and publish the feed yourself anytime you want to add something to your feed.
also after getting ur reply i checked my feed in some online validator site, and got following error:
Missing atom:link with rel="self"
Missing atom:link with rel="self" [validator.w3.org]
