This is a bugfix release that contains a major fix to the canonicalization engine. This bug was introduced in the 1.4.0 release, so it is highly recommended that anyone using 1.4.0 upgrade to the 1.4.1 version. The bug is that signatures containing non ascii characters created by the 1.4.0 library are not generated according to the standard.

Several other important bugs were fixed in 1.4.1. See the changelog for more information.
