Release v3.10.10.0

[3.10.10.0] - 2024-04-22

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
