because a critical bug was solved upstream.
This bug was detected in the past and me and upstream thought it was fixed already[0], then after it was reported again recently[1] we found out that the problem still persisted.
This time I first tried to fix the problem by uploading 1.4.0-2, and while it was on Unstable I think somebody else filled an unblock request and it was granted, but before this version hit testing I uploaded the correct fix (1.4.1-1) to unstable, that's why you can see two changelog entries on the debdiff.
Thanks
