GNU Radio releases 3.6.3.1 and 3.6.4 are now available for download.

Release 3.6.3.1 is a bug-fix only update to 3.6.3, and has no new  
features.

Release 3.6.4 has both bug fixes and new features.

Important new features (3.6.4):

```
  Ability to set processor affinity for GNU Radio blocks

  Tom R. has implemented the ability to set processor
  affinity per block in a flowgraph. This allows the developer to
  limit the execution of a GNU Radio block thread to a set of one
  or more cores, helping optimize inter-core resources in a
  multicore system.

  See:

  http://www.trondeau.com/home/2013/2/7/block-core-affinity.html

  Inclusion of gr_modtool by Martin B.

  Previously available as a stand-alone utility, the gr_modtool
  application for creating out-of-tree GNU Radio blocks has been
  integrated within the main GNU Radio software distribution. The
  features and functionality are the same, but it is now no longer
  necessary to download this separately. See:

  http://gnuradio.org/redmine/projects/gnuradio/wiki/OutOfTreeModules

  Use of GNU Radio preferences in native C++ applications

  Tom R. has ported the GNU Radio preferences system to allow
  its use in GNU Radio applications implemented in C++. Prior to
  this, it was only possible to access the preferences file from
  Python. Until the new manual is updated on gnuradio.org, you
  can see the raw commit here:

  http://gnuradio.org/cgit/gnuradio.git/commit/?id=3643a858

  Addition of GNU Radio block performance counters

  Tom R. has implemented a new capability to allow monitoring
  of peformance statistics of blocks inside a running
  flowgraph. This is an experimental feature that has not received
  a great deal of usage. For more details, see:

  http://gnuradio.org/redmine/projects/gnuradio/wiki/PerformanceCounters
