2.6.3

• Format Python code and enforce a standard style using Black.
• Include a small amount of example data to demonstrate the format and enable example scripts that don't depend on writing data first.
• Add yaml-based GRC files and fix a gr_digital_rf Python 3 bug for GNU Radio 3.8+ compatibility.
• Fix the MATLAB reader when dealing with very high sample rates.
• Fix resampling and channelizer filters in thor.py to correctly account for filter delays and keep the timing consistent.
• Clean up and fix various minor issues throughout the Python codebase.

2.6.2

This is entirely a bugfix release. Notable fixes include:

• Fix error using Digital RF Source with GNU Radio 3.7.12, which changed the type of its input and output signature objects.
• Digital RF Source now outputs zeros for missing values, to minimize impact on downstream processing.
• Make tests compatible with pytest >=4.
• The watchdog_drf module now works for non-inotify observers (i.e. non-Linux).
• Proper cleanup of tmp.rf@*.h5 files when thor and mirror/ringbuffer tools are killed.

2.6.1

This is primarily a bugfix release. Changes include:

• Add raster and vector tools to gr_digital_rf for working with periodic data.
• Disable file locking with HDF5 >= 1.10 for digital_metadata, which restores behavior so it matches that of HDF5 1.8.
• Fix error using digital_rf_sink with GNU Radio 3.7.12, which changed the type of its input and output signature objects.
• Fix the digital_rf_sink block in GRC to correctly pass an empty center frequency.

2.6.0

The main impetus for this release is a complete reorganization of the build system to enable Digital RF to run with Python 3 and on Windows. Major changes include:

• Python 3.5+ compatibility (excluding 'gr_digital_rf' since GNU Radio does not support Python 3 yet).
• Windows compatibility, including conda packages.
• Automated CI testing with revamped Python tests using 'pytest'.
• Python package available on PyPI (for 'pip' install), including binary wheels for Linux, OSX, and Windows.
• Python 'gr_digital_rf' packaged with 'digital_rf' since we no longer require GNU Radio to build (dropping Digital RF C Sink support).
• New 'thor' options:
  • Output channel settings including rational resampling, frequency shifting, and channelizing
  • Clock source (10 MHz ref) and time source (PPS) split out from sync_source
  • Clock lock check with nolock option to skip
  • LO source/export
  • Tuning arguments
  • DC offset and IQ balance
• Updated sounder example transmit script with some 'thor' features.
• Matlab reader fixes for recent data format and packaging as a Matlab Toolbox.
• Various bug fixes and improvements (see commit log for full list of changes).
