CHANGELOG

Change Log for Releases
==============================

## 004.010.000.000
* 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

  - Removed Boost in multiple locations and replaced with standard library
    calls
  - Fix numerous (mostly harmless) compiler and Doxygen warnings
  - Improve CMake linking instructions
* 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: jammy (22.04), noble (24.04), questing (25.10)
    - Fedora: 40, 41, 42
  - Windows: 10 22H2, 11 24H2
  - MacOS: Sequoia (15.6)

## 004.009.000.001
Changes compared to UHD 4.9.0.0:
* Dependency changes
  - Support Boost 1.89.0
  - Drop support for boost below 1.71.0
* Fixes
  - Fix static build of libuhd
* Notes
  - We suggest to only update to this version if the boost 1.89.0 compability
    is required. Apart from the Boost build fixes, there are no other changes
    in this UHD release.

## 004.009.000.000
* 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
  - MacOS: Sequoia (15.2)

## 004.008.000.000

    toolsets. This further improves the ability to design RFNoC blocks and
    create custom FPGA bitfiles.
  - Replaced RFNoC FFT block with a new version
  - Improved Windows installation capabilities including distribution
    of binary Python bindings for Windows though PyPI
* New Features

    - Add GRC support. This allows designing RFNoC bitfiles from GNU Radio
      Companion (GRC).
    - Improve clock connection checks and checks for duplicate connections.
    - Improve IO port compat check (e.g., check if wire widths match).
    - Allow default clocks in domain checks.
    - Simplify image core YAMLs by better usage of RADIO_NIPC parameter.
    - Improve parameter resolution.
    - Improve error messages for missing YAML files.
    - Add --SYNTH and --CHECK options.

      unique seeds with repeat_fpga_build.py and the --fpga-jobs option.
    - 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.
    - Replace FFT block with a new version supporting larger FFT sizes and
      cyclic prefix insertion and removal.
  - multi_usrp

      of Boost.
  - Embedded Filesystem
    - Support for USB Audio devices on E31X, E320, N3XX and X4XX
  - Windows binary installer
    - Simplified the Windows installer experience by reducing the number of
      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
      (pip install uhd)
  - Documentation
    - Add documentation about relationship of MTU, samples per packet and
      atomic item size

      python version is detected.
    - Changed version number format for build Windows binaries to common
      major.api.abi.patch format.
  - MPM
    - Allow images without RF frontend (will only be initialized if FPGA
      reports availability)
    - Fix usrp_update_fs to work for all embedded devices (and not just X4xx)
  - E320: Ensure consistent sequencing when powering on/off GPSDO
  - N310/N300: Fix LO query API for lowband LO

* 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: bionic (18.04), focal (20.04), jammy (22.04), noble (24.04)
    - Fedora: 39, 40, 41
  - Windows: 10 21H2, 11 21H2
  - MacOS: Monterey (12.6)

## 004.007.000.000
* 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
