# Why did a feed file change size or filename?

Feed files can change in size or filename when Spur makes a planned change to a feed's publication — for example, an updated data source or schema version. If an automated ingestion process depends on a specific filename, use the documented stable download mechanism rather than relying on a fixed filename pattern. If a change looks unexpected, contact support with the feed name, version, and the date you noticed the difference.
