 Release notes
 =============
 
+Disco 0.2.1 (May 26th 2009)
+---------------------------
+
+New features
+''''''''''''
+
+ - Support for redundant inputs: You can now specify many redundant addresses for an input file. Scheduler chooses the address which points at the node with the lowest load. If the address fails, other addresses are tried one by one until the task succeeds. See *inputs* in :meth:`disco.core.Disco.new_job` for more information.
+ - Task profiling: See :ref:`profiling`
+ - Implemented an efficient way to poll for results of many concurrent jobs. See :meth:`disco.core.Disco.results`.
+ - Support for the `Curl <https://curl.haxx.se>`_ HTTP client library added. Curl is used by default if the ``pycurl`` module is available.
+ - Improved storing of intermediate results: Results are now spread to a directory hierarchy based on the md5 checkum of the job name.
+
