Hello. The gnat (= 5), libxmlada, gprbuild and dh-ada-library source packages now build with gnat-5. If they are uploaded to unstable, they will make most other packages FTBFS during the migration again, and any fix targeting testing will have to go through testing-proposed-updates. It may be wiser to upload the updated packages one after the other to experimental, then reupload all of them at once to unstable. Any idea?
