Hello<br><br>As far as I can tell setuptools does not always regenerate the source manifest when MANIFEST.in changes, contrary to what the documentation says. That is, if I add a directive to exclude files with the .txt extension to 
MANIFEST.in (after having previously including them), and run the sdist command, such files are still included.&nbsp; I have to remove the .egg-info for things to work as expected. This must clearly be a bug?<br><br>Regards,<br>
