Is there any way to update files stored on Amazon CloudFront (Amazon’s CDN service)?

Is there any way to update files stored on Amazon CloudFront (Amazon’s CDN service)?
Seems like it won’t take any update of a file we make (e.g. removing the file and storing the new one with the same file name as before).
Do I have to explicitly trigger an update process to remove the files from the edge servers to get the new file contents published?

Thanks for your help

    Amazon added an Invalidation Feature. This is API Reference.

    Sample Request from the API Reference:

    POST /2010-08-01/distribution/[distribution ID]/invalidation HTTP/1.0
Host: cloudfront.amazonaws.com
Authorization: [AWS authentication string]
Content-Type: text/xml

<InvalidationBatch>
   <Path>/image1.jpg</Path>
   <Path>/image2.jpg</Path>
   <Path>/videos/movie.flv</Path>
   <CallerReference>my-batch</CallerReference>
</InvalidationBatch>
