------------------
we've finished testing our latest bugfix release; UHD Version 3.7.2 is
now available. It is tagged at
https://github.com/EttusResearch/uhd/tree/release_003_007_002.
Since the last release candidate, we actually fixed an issue with phase
alignment in the X300 for MIMO configurations, among a few other things,
and the binaries for X300 were updated again (B200 images were already
updated in the release candidate). Of course, you have access to all the
binaries through our download utility.
3.7.2 Changelog:
* Fixed X300 phase alignment issues
* Fixed CMake 2.6 incompatibility issues
* EEPROM burner improvements
* Properly flushing PCIe chain on device to prevent stale data.
* Adjusted bus clock rate in FPGA to improve timing.
* Fixed issue where FPGA would fail to load FPGA image over PCIe.
* Fixed incompatibility issue with USRP2 FPGA burner utility.
* Fixed issue where ZPU would report empty NMEA strings from GPSDO.
* Updated some functions to no longer use deprecated Boost calls.
* Fixed issue where libusb would declare 'connection refused'.
* Fixed Windows library package naming.
* Updated documentation.
* Fixed reversed TX / RX colors in X300 LED indicators.
* DBSRX2 now works properly with X300 / X310.
* Updated include files to build on older distros of Linux.
* Fixed issue with 'item32' type converter from GNU Radio.
* Fixed issue where channels on B210 would occasionally not be
phase-aligned.
* Fixed problem causing channels on B210 to swap between runs.
* Fixed issue in N-Series devices causing scaling error @ 50 MSps.
* The B200 / B210 now generates an internal PPS if none is provided.
* Improved performance on PCIe for X300.
* B200 / B210 properly reports clock rate (issue with float comparison).
* Fixed issue with filter selection in B200 that caused loss of RX power.
* Removed ref lock check from X300 where it wasn't necessary.
