[3.10.11.0] - 2024-07-24

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.
• Conda re-rendered.

Testing

• Add Ubuntu 24.04 LTS to CI
• Remove Fedora 38 from CI
• Conda: build with VS2022 for Windows
