Changelog for gnuradio-3.10.11.0-2.24.x86_64.rpm :

* Thu Jul 25 2024 Wojciech Kazubski - Update to version 3.10.11.0- Changed
* Project + Const (keyword) cleanup in a large number of files. QtGUI code uses const in many more places.
* Runtime + Add persistent() function to gr paths module. This function returns either the value of the XDG_CACHE_HOME environment variable, or appdata()/.local/state.
* GRC + Work continues on the Qt version of GRC (gnuradio-companion --qt). While the Gtk version is still the default, we\'re getting close to the point where the Qt version can be the default. + Generated Python code now includes a startup event (flowgraph_started) to the top level class. This was added specifically to avoid a race in the Variable Function Probe block, and may be useful elsewhere. + Struct variables have not been usable since around v3.8. Fixed! + Paths are now based on gr paths, where they were previous hardcoded to the user\'s home directory. + C++ hier block code paths fixed (so hier blocks work again). + Block connection line shape and width are now preferences.
* gr-blocks + New Burst To Stream block transforms a bursty tagged stream into a continuous stream by inserting zeros in the output between input packets whenever no packets are available at the input.
* gr-digital + FLL Band Edge power calculations fixed, along with thread safety issues.
* gr-fec + Unused RS code removed - unlikely anyone will notice.
* gr-filter + Numpy float_ changed to float64 for Numpy 2.0 compatibility.
* gr-fft + Vector version of FFT fft_v library function (calls fftw) thread safety improved.
* gr-uhd + Do not require PyQt5 for non-graphical configurations.
* modtool + Many bug fixes and cleanups, resulting in more reliable operation. That sounds really good, right? + Remove dependency on the \"click plugins\" package. + Appending new blocks to CMake files respects closing parens.
* Build system and packaging + CMake minimum versions were out of sync in different places, fixed. + Incorrect Qwt maximum version removed.- Last two patches gnuradio-fix-error-message-for-Qwt-version.patch and gnuradio-remove-maximum-version-for-Qwt.patch removed as appliedn upstream.- Containd fix for latest spdlog (Tumbleweed).
* Sat May 11 2024 Wojciech Kazubski - Added a patches gnuradio-fix-error-message-for-Qwt-version.patch and gnuradio-remove-maximum-version-for-Qwt.patch (taken from upstream), fixing build with Qwt-6.3.0
* Tue Apr 30 2024 Mikhail Paulyshka - Added python3-QtPy and python3-QDarkStyle runtime dependencies (needed for gnuradio-companion --qt)- Update to version 3.10.10.0- Changed
* Runtime + Modernize location of config files. XDG_CONFIG_HOME will be used if set (often $HOME/.config). This change attempts to be backward compatible with existing config file locations, but be aware that config files may show up in the old ($HOME/.gnuradio/) and new ($XDG_CONFIG_HOME/gnuradio) locations depending on GNU Radio version. Files are not automatically moved, since some users run multiple versions of GNU Radio. + Ctrlport Probe, Ctrlport Probe PSD and gr-ctrlport-monitor. Ctrlport Monitor blocks are still broken.
* GRC + NEW Qt-based front end! Run gnuradio-companion --qt to try it out. This feature is still in testing, so the Gtk front end runs by default. In a future release, Qt will become the default, removing Gtk as a manditory dependency. Maintenance will focus on the Qt front end at that point. + Restore property field background colors (as a View option, off by default) for the Gtk front end. Background colors were previously replaced with textual type string. + The canvas can be panned using the middle mouse button + C++ code generation improvements related to parameters and strings + C++ code generation fixed for Add Const
* gr-audio + Added 96 kHz and 192 kHz selections to ALSA source/sink
* gr-blocks + Float To UChar block adds vector support, and also scale and bias params
* gr-digital + Additive Scrambler adds soft symbol handling + Add callback to set header format in Digital Protocol Formatter
* modtool + Improvements to handling of Python blocks (add, rm, and rename work reliably) + New parseable manifest format (yaml instead of md) to better support the OOT ecosystem + Manifest and examples are installed by \"make install\"
* Build system and packaging + Python byte-compiled (pyc) files are no longer installed, as they are deprecated by Python
* Testing + Added MinGW test runner and fixed various MinGW compilation failures + Update Fedora to test 38, 39 and 40
* Fri Mar 22 2024 Mikhail Paulyshka - Added libad9361-iio-devel build dependency (fixes PlutoSDR support)
* Tue Feb 27 2024 Dominique Leuenberger - Use %patch -P N instead of deprecated %patchN.
* Thu Jan 18 2024 Wojciech Kazubski - Update to version 3.10.9.2- Changed
* Project + Fix a few memory errors in various modules.
* GRC + Fix regressions in bus connections.
* Mon Jan 01 2024 Wojciech Kazubski - Update to version 3.10.9.1- Changed
* Project + Python minimum version is now 3.7.2, vs 3.6.5, to support type hints. + Add tox.ini, so that editors use the same formatting as github CI. + Use pointers to pass s32fc arguments to VOLK in gr-blocks, gr-digital, and gr-dtv to avoid undefined behavior. The fix is conditional on VOLK 3.1.0, which add a new supporting function.
* Runtime + Disallow None for pmt_t arguments in Python. + Support spdlog installations with internal or external libfmt.
* GRC + Use text labels to specify types for block parameters, instead of background colors which were difficult to read/remember. + Enable setting of documentation URLs, relative or absolute in yaml. This allows OOTs to use the documentation link in the block parameter dialog. + Disallow use of block ids that are Python keywords and \"gnuradio\". + Add type annotations in some places (required bump to Python 3.7.2). + Use C version of YAML loader (yaml.CSafeLoader) for better performance. + Connections may have properties for supported connection domains. This feature was added for RFNoC connections. Standard stream and message connections do not support this feature, but they may in future versions. + Check grc file version. The above feature required a version bump to \"2\". Where no connection properties are used, version \"1\" is still emitted. Note that previous versions of GRC do not check for file version. RFNoC flowgraphs with connection properties will fail to load in previous versions as a result. + Fix bug where an impressive number of backslashes were added to some filenames.
* gr-dtv + Read expected data as little-endian
* gr-fec + Add FEC_API to CCSDS Reed-Solomon functions so they can be used by OOTs.
* gr-qtgui + QT GUI Msg Push Button: add a callback for Message Value to allow it to change at runtime.
* gr-uhd + RFNoC Rx-Streamer: Add start stream options + Add back-edge property to RFNoC connections
* Build system and packaging + Use utf-8 encoding when writing files in gr_python_install.
* Fri Oct 20 2023 Wojciech Kazubski - Update to version 3.10.8.0
* Runtime + Add MAP_FIXED to circular buffer implementations using shm_open() and mmap backed by tmp files. + PMTs can be formatted for logging (format wrapper added). + New io_signature::make() variant replaces makev(), and optionally specifies buffer types. + Fix logging params to be compatible with C++20
* GRC + Add \"Choose Editor\" button to Python block properties. Use the GTK app chooser. + Save choice to the config file. + Correct Python Qt imports in Hier blocks and flowgraph templates.
* gr-blocks + Enable building the benchmark testing executable, which runs tests on various math functions. + Repeat block implemented as a basic block (vs sync interpolator) and output buffer allocation fixed. + Add a GRC example for Throttle usage.
* gr-digital + Add set_sps() to Symbol Sync. + Header Format: Fix CRC and OFDM formats, add option to header_buffer to read bits lsb first, and refactor extract_bits functions as templates. + Constellation Sink uses different colors for each input by default. + Rework Constellation Soft Decoder, Constellation Object and LDPC Decoder Definition. + Previously, the LDPC Decoder did not work at all. The sigma parameter was removed from the decoder and an optional noise power npwr parameter was added to the constellation.
* gr-network + Better support for vectorized output from UDP source. The payload size must still be a multiple of item size
* vector size for this to work.
* gr-qtgui + Range widget eng_slider and eng modes can now be selected in GRC. + Range widget and a couple of UHD apps now accept values on editingFinished, rather than on returnPressed. Since UIs generated by GRC do not have OK/Apply for such values, there is no \"correct\" behavior. The behavior is now selectable on the Entry widget. + Frequency Sink startup time improved where sample rate is low
* gr-soapy + RTLSDR buffer size may be specified
* gr-uhd + RFNoC NullSrcSink block added. The block may be both source and sink. + Add support and examples for RFNoC loopback. + RFNoC Rx Radio adds issue_stream_cmd() and block message handler.
* gr-zeromq + Explicitly shutdown and close source/sinks to prevent hangs in some cases. + Require zmq.hpp (cppzmq) version with context_t.shutdown() defined. + If shutdown is not defined, the gr-zeromq is disabled.
* Modtool + Add cmake-format support for generated modules
* Build system and packaging + Update Read-the-docs config to include build.tools
* Mon Jul 17 2023 Wojciech Kazubski - Update to version 3.10.7.0
* Runtime + Setting the minimum buffer size should have the desired effect now, and not be overwritten. NOTE: the value returned by min_buffer_size() is not intended to indicate the actual buffer size. Header Payload Demod was the only block attempting to use this value, and was corrected. + Use a set to store thread group (more efficient) + Message Debug can now output via the logging system + The field prefs.singleton is no longer externally exposed (was unintentional) + PMT dict can be generated more easily using pmt::dict_from_mapping()
* GRC + Save changes under all exit conditions (a couple were previously missed) + Prevent silent Generate/Run failures for unsaved flowgraphs
* gr-analog + C++ code generation for Quadrature Demod + Add max_gain parameter for AGC
* gr-blocks + Probe Rate adds a name parameter, for clearer logging + Selector has a new \"sync\" more that consumes the same number of items from all inputs. Default is now to consume as many items as possible from the active input, and no more than that many items from other inputs. The previous behavior was, well, broken. + Throttle reset item count on restart, to avoid long delays
* gr-digital + Constellation Encoder and Decoder: constellation can be changed at runtime
* gr-filter + Filter design tool: multiple improvements in bounds checking and exception handling + Filter design tool: update QMessageBox to work in Qt5
* gr-network + Multiple memory management errors fixed in UDP Source/Sink and TCP Sink
* gr-soapy + Better AGC and gain behavior in RTL, AirspyHF and SDRPlay blocks + Support bias controls in RTL and SDRPlay blocks

* Fri Apr 07 2023 Jan Engelhardt - Remove unused build dependency on libmpir-devel (gmp-devel was already used anyway).
* Sat Apr 01 2023 Wojciech Kazubski - Update to version 3.10.6.0
* Runtime + Add Python loggers to top_block and hier_block2 + Change the default log level (in the config file) to INFO instead of DEBUG + Logging improvements in the scheduler + Correctly determine native page size for Windows
* GRC + Fixed: opening the source of a hierachical block using the toolbar button produced an error + Use the logger, instead of print statements, in generated top blocks + Remove libX11 load from generated Python code - this was unncessary and produced warnings + Choose Editor dialog stays above parent
* gr-analog + Signal Source: option to hide the message port
* gr-blocks + Throttle: supports max time or number of samples per work iteration, useful for reducing latency at low sample rates + Delay block: option to hide the message port + File Meta Sink: fix missing Python import in template code
* gr-channels + Default taps should be 1.0, not 1.0 + j1.0

* gr-qtgui + Histogram Sink: calculate range of bins correctly to avoid strange distributions + Save (to image) dialogs add file extensions and have a Save button (i.e., they work now)
* gr-soapy + Sources: add tags when the frequency changes
* gr-uhd + Support for more RFNoC blocks - Fosphor, which produces data to drive an on-screen OpenGL- based renderer which is expected to be in the next release - Moving Average - Switchboard - Split Stream + FFT: add properties for direction, magnitude and scaling + RX Stream: flush after timeout + Fully support multi-channel TX/RX (params were available for one one channel)
* gr-vocoder + Add a number of new codec modes for Codec2 and FreeDV
* gr-zmq + Selectable bind/connect to support more flexible ZMQ patterns and NAT\'d networks + Stream sources produce when available, instead of waiting for a buffer to fill, helping with latency
* Modtool + Use interp and decim keywords correctly when generating blocks- Added a patch gnuradio-not-install-freedesktop-files.patch to revert commit 7c87800f1d7e85589678f01281b45451085c7482
* Wed Jan 25 2023 Wojciech Kazubski - Update to version 3.10.5.1

* gr-filter + Performance improvement in PFB Arbitrary Resampler when interpolating, especially at low rates
* gr-qtgui + Fix display of tags on the last sample (would be dropped) + Python wrapping: replace pyqwidget() with qwidget() - this is not intended to be a visible fix, but is mentioned here in case it causes trouble for anyone + C++ generation - add double quotes to cpp_opts keys with colons - position windows correctly depending on gui_hint - use option attributes to generate enums - use the cpp enums for wintype and trigger_type
* gr-uhd + Fix input filename in freq hopping examples + Make RFNoC a separately enabled component in cmake + Python bindings for rfnoc_graph,_rx/tx_streamer
* gr-video-sdl + U and V channels were reversed on sink blocks

Raw types are validated. Port connections are checked by type rather than by item size. + Variable names that cause name conflicts in Python code (e.g., with package names) are rejected + Bus logic fixes + Blocks can no longer be dragged off the screen and lost forever
* gnuradio-runtime + Remove pmt::pmt_
* functions, which were not actually implemented. This is technically an API change, but any use of the API would have resulted in a link error. + Remove Python bindings for internal buffer functions
* gr-analog + Added an example for PLL Frequency Detector + Better names for parameters in PLL GRC blocks
* gr-blocks + Consistent naming for Vector Length parameter in GRC blocks + count_bits uses VOLK popcnt for better performance (used for example in the Correlate Access Code block) + Rotator block phase increment parameter is controllable via a message, and a tag can be added at the point where the increment is adjusted

* gr_filter_design + \"File/Save\" is disabled until the taps have been computed, and the GUI is reset after a save, to make it clearer which data is being saved. + Entries are hidden for parameters that do not apply to the selected filter type. + Save window type as an integer instead of a Python enum name
* gr_modtool + Improve validation of module and block names
* Build System and Infrastructure + Improved messages related to dependencies MPIR and GMP. Only one of these packages is required, and the previous error messages were confusing. + Cleaner builds for Windows and Conda. A number of general cmake improvements have resulted from this work. + In-tree packaging files for DEB and RPM, used with Launchpad and COPR + Added man pages for GNU Radio tools + Test code generation for all in-tree GRC examples + In GrPybind.cmake, PYBIND11_INCLUDE_DIR (incorrect) was changed to pybind11_INCLUDE_DIR- Update to version 3.9.1.0:
* Project Scope + (internal) Build system improvements and fixes + (internal) Use C++14 features instead of Boost where possible + Fewer compiler warnings (due to fixed code, not removal of warnings!)
* OOT Support + cmake: standard FindGSL used in lieu of custom one, so OOTs should no longer copy this module from the GNU Radio tree if needed + modtool: better exception/error handling + modtool: will non-interactively add blocks with no parameters (--argument-list=\"\") + PyBind11 header hash hotfixer + (gr-utils/bindtool/scripts/binding-hash-hotfixer.zsh) makes life easier

* gnuradio-runtime + Default buffer size can be adjusted by setting buffer_size in the [Default] section of the GNU Radio config file. Otherwise, the longstanding default of 32768 is used.
* gr-blocks + Message Debug: prints warning when a non-PDU message is received on the Print PDU port + File Source handles EOF properly in non-seekable files (e.g., pipes) + Several bounds checking and boundary condition improvements + Remove DC Spike AutoSync algorithm fixed

In v3.11, only the dict format will be accepted. + Command note: freq messages in this version must be dicts. Additionally, the direction key must be present and set to TX or RX. + set_filter() adds chan parameter + Python generated code improved for FE corrections + Allow control of frequency and gain in both directions at the same moment + Add command handler for mtune (\"manual tune\") + Add GPIO control via messages + Add start time param to GRC blocks + Support streaming modes: STREAM_MODE_START_CONTINUOUS, STREAM_MODE_STOP_CONTINUOUS, STREAM_MODE_NUM_SAMPS_AND_DONE, STREAM_MODE_NUM_SAMPS_AND_MORE + Documentation improvements + Tag sink demo example + Better logging of over/underflows, time errors and time tags + Added Python binding for ALL_LOS (all local oscillators) + uhd_fft application X11/Qt related cleanups
