I have released a new version of the source package for Unix-like operating systems (read the announcement).

You will notice that the package has been renamed to "MiKTeX Tools". I want to emphasize the fact that the package is not a TeX system/distribution.

I have fixed a MiKTeX specific pdfTeX bug: an extra byte was appended to an embedded file attachement. The bug has been fixed in MiKTeX-pdf(e)tex version 2.4.2140.
