Changed
SoapySDR support (gr-soapy)
GRC
Parameter expressions and/or values can be displayed in blocks on the flowgraph. Previously, only values were displayed. Look for the "Show Parameter ..." toggles under the View menu.
Deprecated blocks are shown in a distinct color (orange), and the optional deprecated property has been added to block yaml
Dark theme works better, especially for parameter fields
Vector length is now correctly applied to all input ports
Validation has been improved. 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-digital
MPSK example updated to use a Linear Equalizer (replacing deprecated block)
gr-filter
Filter Delay documentation improvement
Interpolating FIR filter can generate C++ code
gr-dtv
VL-SNR bugs fixed (incorrect constants).
gr-qtgui
Improve autoscaling for vector sinks
Fix floating-point resolution problems in several widgets, due to interpretation of PMT doubles as floats
gr-uhd
Add policy enum to Python bindings for tune_request
Additional time spec options on UHD blocks (PC Clock on Next PPS, GPS Time on Next PPS)
Fix up code that was generating warnings
Fix command handler logic to apply commands from messages to the correct channel
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
