Comment 3 for bug 401043

This is not a Soyuz bug :)

I chatted to mvo about this and what happens is that there's a cron job that scrapes the archive every 4 hours and populates changelogs.ubuntu.com.

This can be made considerably more efficient if it uses the Launchpad API instead, using a combination of:
    Archive.getPublishedSources(created_since_date=xxxx)
which returns a collection of SourcePackagePublishingHistory items, each of which has a changes_file_url property that is the unmodified changes file for the upload.

Michael advised to leave the bug filed on Ubuntu for now, assigned to him. Bug Squad members, please leave it for him.
