Versions

Backward compatibility

ftputil follows semantic versioning. This means only changes in the first part of the version number break backward compatibility.

Even if a version of ftputil breaks backward compatibility, I try to limit the effects, so you may not be affected. Check the release announcements on the mailing list for details of new backward-incompatible versions before making a version switch. Here are two examples. If you’re unsure how a new version might affect you, please ask on the mailing list.
