Hi, Signed&Uploaded, thanks for your contribution to Debian!
>I don't think that update will require a transition. reverse-depends -b libec-dev reverse-depends libec-dev reverse-depends libec2 returned nothing, so I sponsored the package. there is no need for a Debian transition, but it might be needed if you have some local packages linking it. (there has been some headers file removed/moved, so some API changes might have been there) cheers, G.
