In this release the whole code has been rewritten. The previous release package has been splitted into four single packages. Two of them are libraries providing common features (ibrcommon) and specialised classes for building and working with DTNs (ibrdtn). The package ibrdtnd contains the DTN daemon and some standard applications are contained in tools.

Minor GCC 4.4 patch and missing LICENSE file added.

This is a bugfix release. The used protocol version is still 0x06 as the DTN2 reference implementation version 2.6.

This is the first public release of the IBR-DTN implementation. It's still a experimental version and probably full of bugs.

The used protocol version is 0x06 as the DTN2 reference implementation version 2.6.
