Hi All, The UHD-4.8.0.0 release is now available.\ This release includes the addition of rfnoc_modtool and further improvements \ to RFNoC Image Builder, a new RFNoC FFT block and improved Windows installation \ capabilities including distribution of binary Python bindings for Windows though PyPI. \ For a complete list of new features, updates and bug fixes see the CHANGELOG (see also below).

Thanks,\ Marian Koop CHANGELOG: UHD 4.8.0.0 **Highlights / Main Changes** * Addition of rfnoc_modtool and further improvements to RFNoC Image Builder\ 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** * Image Builder * 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. * Add support for building an FPGA image using multiple parallel jobs and\ 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 * Add Python bindings for get_user_settings_iface() * General UHD * Add modules.d support * Add uhd::find_uhd_command() API call * Remove old-style Boost.Asio usage for compatibility with future versions\ 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 **Dependencies changes** * Increase minimum required versions * CMake to 3.12 * Boost to 1.66 **Bug Fixes** * General UHD * Fix compatibility with DPDK >= 22.11 * Fix compiler warnings for better compatibility with C++17 and 20. * Add logic for loading uhd.dll from the correct path for Windows with\ Python3.8+. * Add logic to warn about potential incompatibilities when importing\ Python bindings. * Remove duplicate results from find * Release GIL when calling find from Python which improves response time\ for large setups. * Python support * On Windows now also enable building python support if minimum supported\ 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 * RFNoC * RFNoC DDC/DUC block (used in all Gen-3 USRPs and X410): Fix fractional\ frequency offset. * Fix AIS/spp calculation (e.g., for connecting FFT blocks). * Fix USE_IMPL rendering for the addsub block. * Image Builder * Fix colors * Fix error message for missing control SEP * Improve error reporting for invalid connections * Accept \~ and \~user on command line * Fix deprecated usage of yaml.load() * Ensure correct device tree files generation when choosing a custom build\ directory * rfnoc_modtool * Fix generation of noc_shells **Validated OS Environments** (Versions for build and runtime dependencies can be determined from the\ docker container definitions in the UHD repository at [.ci/docker/...](https://github.com/EttusResearch/uhd/tree/v4.8.0.0/.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)
