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" 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.
