I just released NBD 3.9

When generating the changelog, I noticed that 3.8 happened two weeks shy of a year ago, which is far too long. As a result, the new release has many new features:

• AF_UNIX support
• New "treefiles" mode, which exports a gazillion of page-sized files; useful for exporting things which are stored on an SSHFS or amazon AWS (trough FUSE) or similar, where every write causes an upload to the backend storage
• New "cowdir" option, allowing to specify where copy-on-write files are written.
• Minor changes so that nbd-client can now also be compiled for the Android platform. This required removal of the -swap command line option, which requires the mlockall() system call, unavailable on Android.
• Protocol update: a reserved bit is used to avoid sending the 124 bytes of useless data at the beginning of the negotiation. The change is implemented so that things will still work with clients not supporting this option, however.
• gznbd is now built by the same build system, rather than a separate one. Note however that gznbd is still unmaintained; it should be considered a "contrib" feature.
• "nbd-server -V" will now output the nbd-server version number.
• Fixed test suite on non-GNU getopt() implementations
• Various fixes found through Coverity and the clang static analyzer, and lots of other minor things too small to mention here.

Get it at the usual place.
