Important new features (3.6.4):
Ability to set processor affinity for GNU Radio blocks
Tom Rondeau 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 Braun
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 Rondeau 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
<http://gnuradio.org>, you
can see the raw commit here:

Addition of GNU Radio block performance counters
Tom Rondeau 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
