The package has a debian/watch file, but the last attempt
to use it for checking for newer upstream versions failed with
an error:
In debian/watch no matching files for watch line https://github.com/facebook/rocksdb/tags .*/archive/v?([0-9][0-9\.]*)\.(?:tgz|tbz2|txz|tar\.(?:gz|bz2|xz))
testing migration
This package will soon be part of the auto-rocksdb transition. You might want to ensure that your package is ready for it.
You can probably find supplementary information in the
debian-release
archives or in the corresponding
release.debian.org
bug.
