Package: src:openjpeg Version: 1:1.5.2-3 Severity: important src:openjpeg2 has been uploaded in Debian for while now. It is available in stable (jessie) and it's functionalities are identical to src:openjpeg (if not better).
It does not make sense to maintain two low level API for dealing with JPEG 2000 with very close API. The concerns are: - duplicate effort from a security point of view (CVEs), - possible symbols conflicts as ABI has changed drastically from one version to the other.
