uhd (4.10.0.0-0ubuntu1) ubuntu_release; urgency=low

  * Highlights / Main Changes
    - Support for USRP X420
    - Addition of timed complex gain feature, which allows setting a complex gain
      value to fix phase and amplitude of signals from radio blocks
  * New Features
    - CMake:
      - Create UHD::uhd package for improved integration in downstream build
        processes. The init_usrp example is used to showcase this feature.
      - Improved options for RFNoC OOT modules to write unit tests.
    - Add helper routines to up- and download data (reliably) from and to the
      DRAM block
    - X310: Allow daughterboards to set dboard clock rate
    - Improve finding of MPM-based devices by making parts of the find call
      asynchronous and allowing to skip reachability checks.
    - RFNoC:
      - Added new optional feature to all Radio blocks - Timed complex gain:
        - Allows specifying complex gain coefficients to be applied to all
          TX and/or RX samples of a radio channel at the specified time.
        - Enabled by default for all TX and RX channels of the radio blocks,
          but can be disabled at FPGA build time via the `EN_COMP_GAIN_TX`
          and `EN_COMP_GAIN_RX` parameters of the radio blocks.
        - NOTE: For the x440_X4_400 default FPGA design provided with UHD,
          enabling this feature for all 8 RX and TX channels necessitated
          restricting the existing crossbar connections between the replay
          blocks and the radio blocks. As a result, only blocks with the same
          indices can be connected (e.g. replay0<->radio0 and replay1<->radio1
          only) when using this pre-built USRP FPGA image.
      - Blocks may now drive the front-panel GPIO pins on all RFNoC-capable
        devices. New IO signatures are added, and all device BSPs have IO ports
        for accessing the GPIOs. Device controls are updated such that the user
        can choose the source for GPIOs dynamically in this case (i.e., the
        radio blocks and other GPIO sources are still available). In some cases,
        the device BSP HDL had to be significantly refactored.
      - Add names and descriptions for block's and module's YAML files, so that
        other tools may read information about those in an automated fashion
      - Allow `mtu` stream argument, which overrides the MTU value that is
        derived from the link information.
      - Action handling is now moved to its own thread (there is one action
        handling thread per graph). This allows actions to be handled
        asynchronously, e.g., when triggering actions from async message handlers.
      - Add radio_state IO signature, so that other blocks can monitor the ATR
        state of radio blocks.
      - All RFNoC devices can now take an `mtu` stream argument (which overrides
        the detected link MTU) and a `force_mtu` device argument (which skips
        automatic MTU detection and forces a fixed value). These are helpful in
        scenarios where a specific network topology interferes with path MTU
        discovery, and for remote streaming when the MTU for a remote stream link
        cannot be inferred from UHD.
      - rfnoc_modtool has improved support for generating unit tests.
      - Add PPS IO signature for all targets
      - Add stream command to start receiving when a transmit occurs
      - Null source/sink: Add finite mode.
      - Add UX1/UX2/UX4 QSFP configurations for X4xx
  * API Changes
    - meta_range_t and uhd::dict can now be initialized from initializer lists
    - Add rfnoc_graph::get_chdr_xport_adapters()
    - Python API now allows creating SubdevSpec from a string
    - Some public APIs that used `boost::optional` now also work with `std::optional`
    - Unit tests for RFNoC blocks (in-tree and out-of-tree) no longer require a
      dummy implementation of `~make_args_t()`
    - `uhd::cast::to_str()` was added and `uhd::cast::from_str()` was extended to
      be a full replacement for `boost::lexical_cast`
  * Examples
    - Overhauled many of the examples to improve documentation, as well as some
      minor conveniences or bug fixes
    - Added continuous streaming to tx_samples_from_file
    - Improved gpio example.

      - Fix various simulation-related bugs
    - USRP Simulator: Update to match current UHD.
    - multi_usrp:
      - Improved bank name check in multi_usrp::{set,get}_gpio_attr()

    - USRP1: Fix converter name in property tree
    - FPGA:
      - Fix various simulation/testbench issues.
      - Improve resource utilization in various places.
    - MPM:
      - Fix file descriptor leaks by using with/open everywhere.
      - Fix double-free issue in rpclib.
      - Remove tolerance for non-existing EEPROMs.
    - Examples: Properly report errors when opening a file failed.
    - Python: When installing into venvs, no longer force a reinstallation of
      dependencies.

uhd (4.9.0.0-0ubuntu1) ubuntu_release; urgency=low

  * Highlights / Main Changes
    - Support for USRP B206mini-i
    - Support for OBX daughterboard
  * New Features
    - OBX daughterboard and B206mini support added.
    - X3x0: Add support for the gps_iface feature. This allows sending arbitrary
      commands to the GPS module.
    - rfnoc_modtool: Add a new subcommand, `make-yaml`, that generates a block
      YAML file from some user inputs. When calling `rfnoc_modtool add`  without
      a valid block YAML file, the tool will now automatically call `make-yaml` to
      generate a new YAML file.
    - Added support for processing multiple samples per cycle in FFT block.
    - LabVIEW/USRP: New repository containing example applications which 
      demonstrate how to use NI LabVIEW with USRP devices via the UHD APIs.
      (https://github.com/ni/labview-usrp-examples)
    - Improved RFNoC OOT Block support:
      New repository containing official RFNoC OOT Blocks
      (https://github.com/EttusResearch/rfnoc-oot-blocks)
      - Added new RFNoC Aurora Block for TX and RX remote streaming applications
        to and from Aurora capable compute nodes like FPGA Coprocessors.
    - Enhanced the UHD Windows installer to automatically install Windows
      driver packages into the OS, eliminating this manual post-installation
      step for B-Series USB devices. 
  * API Changes
    - `uhd::math::gcd` and `uhd::math::lcm` are removed from the public
       headers. Use `std::gcd` and `std::lcm` instead if C++17 is available,
       or `boost::math::gcd` and `boost::math::lcm` if not.
    - When calling `recv()` on an RX streamer connected to an RFNoC device, we
      no longer artificially inflate the timeout value. The old behaviour was
      in some cases abused to detect overruns, but this is not a reliable method
      and is now explicitly declared unsupported.
  * Bug Fixes
    - RFNoC
      - Calling `recv()` on an RX streamer connected to an RFNoC device with a
        zero timeout value now correctly returns immediately.
      - rfnoc-gain: Moved the fpga/ subdirectory under rfnoc/. This way, the
        directory structure inside the OOT module is identical to the directory
        structure after installation.
    - X410:
      - Fixed NCO reset mechanism that caused ADC self-cal errors to occur during
        reopening of a UHD session when timed tune commands were previously used.
  * Removals / Deprecations
    - Removed tools/uhd_dump. This tool is obsolete, the USRP X3x0 is not even
      compatible with it any more. Dumps can be recorded and analyzed with wireshark
      and the UHD dissectors in here.
    - Removed network_relay example.
  * Validated OS Environments
    (Versions for build and runtime dependencies can be determined from the
     docker container definitions in the UHD repository at .ci/docker/...)
    - Linux:
      - Ubuntu: focal (20.04), jammy (22.04), noble (24.04), plucky (25.04)
      - Fedora: 40, 41, 42
    - Windows: 10 22H2, 11 23H2

      - Add 'q' (or 'quote') filter to YAML files to allow quoting strings.
    - rfnoc-gain (OOT RFNoC example)
      - Overhaul directory structure, and rename to rfnoc-gain from
        rfnoc-example.
      - Simplify dynamic loading of OOT DLLs by using the new modules.d feature.
      - Add CE clock support to gain block. This enables the example on X4x0.
      - Add a GNU Radio subdirectory with examples of how to run the gain block
        in GNU Radio.
    - Add rfnoc_modtool. This is a command line utility to help design OOT RFNoC
      blocks and replaces the previously available blocktool.
    - RFNoC
      - Add tune requests. This allows tuning a complete graph as known from
        multi_usrp instead of single blocks individually.

        individual downloads from 4 (for USB devices) to 2, by including
        libusb.dll and USB driver installer files into NSIS-built installer
        binaries.
      - Add new cmake feature option called ENABLE_EXTEND_WIN_PACKAGING,
        which defaults to off. Enabling this feature will cause a number
        of convenience components to be included into the Windows deployment
        package (aka. installer).
        Enabling this feature has no effect on other platforms.
      - Added binary Python bindings for Windows installable through PyPI

uhd (4.7.0.0-0ubuntu1) ubuntu_release; urgency=low

  * Highlights / Main Changes
    - Major updates to rfnoc_image_builder (a98ce26). This change adds support for
      defining transport adapters in the image builder YAML files, adding custom
      modules, and more.
    - Updated embedded OS on file system images for E3xx, N3xx, and X4xx devices
      to Yocto 4.0 (kirkstone).
  * New Features
    - General
      - Allow installing only Python-based utilities (e.g., rfnoc_image_builder)
        by adding the ENABLE_PYMOD_UTILS option to CMake.
      - Added ability to query dot representation of RFNoC graph
    - Python support
      - Added DRAMReceiver class and amend rx_to_file.py example to use new class.
        This supplements the DRAMTransmitter class and simplifies using the DRAM-backed
        RFNoC replay block to when signal bandwidth exceeds available streaming bandwidth.
    - CMake
      - We now search for a system version of Pybind11 before falling back to the
        bundled version. The system version is preferred, and the bundled version
        may be removed in a future release.
    - RFNoC
      - Image builder: Major update, which adds support for defining transport
        adapters in the image builder YAML files, adding custom modules, choosing
        custom directories for build, IP, and intermediate files, building IP
        only, saving Vivado projects, and more. Image core YAML files created with
        this version are not compatible with previous versions, and vice versa!
        Also adds many more checks to avoid building bitfiles that are either
        incomplete, or valid but probably not the desired outcome.
      - Added support for defining custom register spaces in RFNoC blocks.
      - Added license checking subsystem. This allows creating RFNoC blocks that
        require a license key to operate.
      - Add device DNA feature for X310, X410, X440. This allows reading back the
        FPGA's DNA, which is a unique identifier.
    - Embedded OS for E3xx, N3xx, and X4xx devices
      - With the switch to Yocto 4.0 (kirkstone), the SD card and eMMC images no 
        longer pre-populate the second system partition. Refer to the device 
        specific "Updating Filesystems" section in the user manual for how to populate it.
        This reduces the size of compressed .sdimg filesystem images.
    - X440
      - Added new guided log info mode to provide more information about the Nyquist
        zone in which the chosen frequency is located. These additional info logs
        are enabled by default. For disabling the guided mode, add the entry
        `guided_mode=false` to the UHD config file in the "Global" section.
    - Examples
      - rfnoc-example now also generates Python bindings for OOT block control functions.
  * Dependencies changes
    - Increase minimum required version
      - Python to 3.7.0
      - Pybind11 to 2.7.0
  * Bug Fixes
    - General UHD
      - Fix issue with undefined HOME or XDG_CONFIG_HOME
      - Fix compilation error with boost 1.85.0 (closed issue 740)

      - Demoted safe call logging to warning
      - Fixed outstanding clang-format issues
      - Fixed compiling with gcc 13.2
      - Removed superfluous usage of const in return values
    - Python support
      - YAML files are now listed as part of the package
      - Fix setting start_time having no effect
    - RFNoC
      - Add EOB to source port of null_src_sink block
      - Fix RFNoC graph action queue lockup on action exceptions
      - FIR filters now uses newer IP revisions
      - Reverse FIR filter coefficients now get embedded in DSPE48
    - B2xx
      - Fixed FRAC2 calculation (closed issue 684).
      - Fix DC truncation bias by adding rounding to DDC chain
    - X310
      - Fix warning about duplicate reg
      - ubx
        - update ubx xcvr mode options
        - write output power to correct LO
        - Fix width of gain register
    - MPM
      - Deactivate explicit DAD (Duplicate Address Detection) on int0 interface
        since this is the default behavior of systemd v250.5 (Yocto release kirkstone)
        for static IPv4 addresses if the IP address is a link local address.
      - Correct outdated mender command in prints of usrp_update_fs utility
      - No longer import from from rpc_server when already importing usrp_mpm
      - Demoted log level of ECHO send error
      - No longer print iptables errors when setting up forwarding
    - X400 Platform
      - Add PPS interface to X410/X440 BSP
      - Add netlist make flow
      - Update PS DRAM speed bin
      - Replace Ethernet transport adapter
    - X410
      - Set Locale for ZBX Lattice build
      - Improve Lattice make flow
    - X440
      - Fix error in master clock table for 1000MHz mcr.
      - Place SPI into IOB on X440
      - mpm
        - Add error for recurring TA node inst values
        - Fix warning about different converter rates
        - Fix MTS skip for dual-rate
        - Use greatest converter rate for sysref rate
        - Add warning for bad conv rate order
        - Enable multiple LMK VCO rates per MCR
    - Examples
      - Fix rx_samples_to_file failure for multichannel fullpath.
      - Fixed bugs observing cmd argument -c in remote_rx.py example.
      - Updated tx_waveforms examples now also use timed commands during
        frequency tuning for all devices except for x410.
        On X440 this allows reproducing specified channel to channel phase alignments.
      - Consistently comment out sections in rx_samples_to_file.
