+uhd (3.10.1.1-0ubuntu1) trusty; urgency=low
+
+ - Docs: The protocol for Gen-3 devices is now consistently referred to as CHDR.
+ - X300: Fixed EEPROM corruption bug (happened when two processes would access
+ find routines on the same device at the same time). Improved initialization
+ time. CE clock is now 214 MHz. Fixed channel list generation. Find routines
+ now more lenient in case one devices fails (others can still be found then).
+ Improve PCIe behaviour. Fix timed commands for non-TwinRX dboards. Improve
+ AXI Interconnect (faster, improved build timing).
+ - N230: Use second_addr (like X300).
+ - C API: Added UHD_VERSION macro. Fixed online rate change.
+ - Utils: Minor fixes to uhd_images_downloader.
+ - Build/CMake: Fixed some Py3k build issues. Fixed many compiler warnings. Allow
+ to specify package names.
+ - RFNoC: Fixed sampling rate mismatch error. Noc-Shell uses a non-cascaded 2-clk
+ FIFO. Increase default FIFO sizes on DUC and DDC blocks.
+ - UBX: Force on RX driver to eliminate transient.
+ - Transport code: Fixed memory leak.
+ - FPGA repository: Merged usrp3_rfnoc and usrp3 directories again. Cleaned up
+ superfluous files. Clean separation between Gen-3 and other devices in usrp3.
