Hi,
Our system has detected the upload of ns3 3.48-1 as being a transition risk: it
drops binary packages that other packages in unstable still depend on. A change
like this normally needs to be coordinated with the Release Team and uploaded
to experimental in the meantime.
Please let us know how to proceed by visiting the link below (you'll be asked
to log in with Salsa first):
https://dfsg-new-queue.debian.org/transition/qPTVoAzo5f_3UIedYqNoEiLlJKHcI7ow
There you can either confirm the rejection (so you can re-upload to
experimental) or tell us no transition is needed and ask us to review it anyway.

Thanks!
