Package: src:libxmlada Followup-For: Bug #903380 Hello.
Updating libxmlada for a new unicode version requires a renaming of the -dev package for xmlada and all its reverse dependencies. Such migrations happen in experimental. Most packages are already renamed for unrelated reasons (gcc-8 migration and new XMLAda release). The XMLAda update should be straightforward, but will have to wait for the reupload of migrated packages to unstable, once all such changes are finished in experimental.
