Description

Release v3.9.4.0 is appearing a little early because of a couple of regressions in v3.9.3.0. While we were at it, we pulled in a few more helpful commits from the master branch.

This is an API compatible update to GNU Radio 3.9. Code written for 3.9.X versions should compile and link without modification. The ABI is not guaranteed to be compatible, so a rebuild of OOT modules may be necessary.

Changes Regressions Fixes
  • Remove #include <filesystem> (C++17 feature) from one file
  • Restore pyqwidget() in gr-qtgui
GRC
  • GRC now runs on Fedora 35 ... Gtk initialization checks were too strict
  • Add keyboard shortcuts for zoom
  • Account for scale factor when computing drawing area size
  • Use font size from config for block comments
  • Change type aliasing to allow interleaved short/byte to be connected to vectors of short/byte. Stricter type checking was added previously and caused some blocks to be unconnectable when using these types.
  • Required params no longer default to 0 when left empty. This caused hard-to-find errors. Older flowgraphs that have empty required fields will need to be fixed.
  • Tooltips fixed for categories and modules
gr-runtime
  • PMT uses the VOLK allocator for vectors
  • get_tags_in_window() Python wrapper calls the correct function
  • Add --pybind option to gnuradio-config-info to get PyBind11 version
gr-blocks
  • Add example for XMLRPC
  • Add a unit test for Message Strobe
  • Fix C++ support for Unpacked to Packed
gr-channels
  • RNG seeds are initialized correctly
gr-digital
  • Fix yml file for Header/Payload Demux
gr-network
  • Suppress warning in tuntap
gr-qtgui
  • Remove unusable int type in Number Sink yml
  • Use no_quotes() function in several yml files
modtool
  • Hashes can be fixed using modtool using --update-hash-only
  • Use tempfile() instead of /tmp in bindtool and modtool
  • Use static_cast instead of reinterpret_cast in templates
  • Correct broken Python general block template
Build system
  • Better check for Boost version
  • Determine the Python prefix more reliably
  • Use GR-specified compiler standard (C++14) in gr-soapy, instead of the SoapySDR standard (C++11)
  • GrPython.cmake is compatible with older cmake
Documentation
  • Man pages are in-tree
  • Repair many examples, especially in gr-digital
  • Allow UTF-8 in pydoc templates
CI
  • Execute make install during test
  • Add Ubuntu 18.04 test target
