GNUnet 0.5.1 released

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

GNUnet 0.5.1 finally made it out of the door.

There are a few new features, like that you can explicitly specify the degree 
of anonymity that you require (how much traffic you need to hide in) and an 
improved database handling that will allow you to break the boundary of 2 GB 
of inserted or migrated (not indexed!) content.

The release also now supports libgcrypt (big thanks to Werner Koch, the 
libgcrypt maintainer, for his help). Achieving compatibility between OpenSSL 
and libgcrypt prompted two minor changes to the encoding of RSA encrypted 
data, so if you see "failed verification" messages, that's just peers running 
the old protocol. libgcrypt still fails sporadically on RSA decrypt (or 
signature verify) operations and you need the very latest version of 
libgcrypt. But for now, you can also still use OpenSSL which is suggested 
until we have solved the remaining problems. 

Other than that, we've fixed the usual sway of segmentation fauls, memory 
leaks and deadlocks (and probably added a few new ones to ensure that there 
will be an 0.5.2 :-). 

Oh, and if you missed it so far, libextractor 0.2.0 has been released and is 
now required for GNUnet 0.5.1.
