As always, we at Ettus Research would like to thank all of the UHD users in
the open source SDR community.  This release contains commits from users in
the community that submitted pull requests against the UHD
<https://github.com/EttusResearch/uhd> and FPGA
<https://github.com/EttusResearch/fpga> repositories as well as many
commits that are a direct result of issues reported back to us by users
like you through the UHD <https://github.com/EttusResearch/uhd/issues> and
FPGA <https://github.com/EttusResearch/fpga/issues> issue trackers,
the USRP-users
mailing list
<http://lists.ettus.com/mailman/listinfo/usrp-users_lists.ettus.com>, and Ettus
support <support at ettus.com>.  You have all helped contribute to the
continued improvement of UHD.  Thank you!
