Folks,

I am proud to announce the release of uDTN version 2. uDTN is the open source bundle protocol implementation for WSN nodes running Contiki. It is interoperable with IBR-DTN. Further information can be found in our Wiki:
  https://trac.ibr.cs.tu-bs.de/project-cm-2012-mudtn

Code can be obtained from our GIT:
  http://git.ibr.cs.tu-bs.de/?p=project-cm-2011-udtn.git;a=summary

== New Features ==
* Support for bundle status reports (requested reports are sent, applications have to interpret them themselves)
* Bundles are deleted when delivered report arrives
* Support for bundle priorities (storage will not overwrite high-priority bundles with low-priority bundles)
* Duplicate Detection is now done when bundles enter the agent to prevent duplicates from taking up storage
* Significantly more regression tests
* Dramatically improved test suite (thanks Georg and Julian)
* Bundle deletion strategy can now be configured via defines
* Backoff in Convergence Layer to avoid jamming the wireless medium
* RSSI is now available on received bundles in the bundle struct
* Improved interoperability with IBR-DTN
* Bundles are locked in storage now while they are being delivered to an application

== Fixed Bugs ==
* Greatly improved stability, many many more error checks
* Fixed TMote Sky memory alignment bug that prevented bundle from being delivered correctly (thanks André)
* Fixed many potential memory corruption issues
* Bundle ID is now correctly hashed over 5-tuple identifying a bundle
* COFFEE-based storage is now stable and parses bundle ids correctly

== Known Problems ==
* Bloomfilter-based redundancy module produces collisions (use at your own risk!)

Cheers,

Bastian
