It depends what you call a release.   I consider it released as 0.63rc1.

Since it isn't just Perl code (there's quite a chunk of C in there) things like architectures may present issues so it would be really
good to get some feedback.

At the moment I don't know how many people have actually used it. At least two if you look at the mailing list posts.  One of those is me. :)

Bear in mind that in 0.62 the bundled zlib doesn't need to be compiled.

Just some some thoughts / questions on the zlib CVE. There are two path's of vulnerability for the BackupPC server. One is the distro installed zlib and the other is the zlib bundled in BackupPC to date. The distro installed zlib supposedly will be patched soon, not as of yet. Anyone who has access to this server could avail themselves of the vulnerability till it is patched. Once it is patched then the only users who have access to the bundled zlib are those trusted BackupPC admin users. The client users shoudn't have direct access to the bundled zlib, correct? Just trying to get an idea of the risk level for the bundled zlib.
