Release Candidate v3.10.6.0-rc1

[3.10.6.0] - 2023-03-31 (planned release date)

Changed

Runtime

• Add Python loggers to top_block and hier_block2
• Change the default log level (in the config file) to INFO instead of DEBUG
• Logging improvements in the scheduler
• Correctly determine native page size for Windows

GRC

• Fixed: opening the source of a hierachical block using the toolbar button produced an error
• Use the logger, instead of print statements, in generated top blocks
• Remove libX11 load from generated Python code - this was unncessary and produced warnings
• Choose Editor dialog stays above parent

gr-analog

• Signal Source: option to hide the message port

gr-blocks

• Throttle: supports max time or number of samples per work iteration, useful for reducing latency at low sample rates
• Delay block: option to hide the message port
• File Meta Sink: fix missing Python import in template code

gr-channels

• Default taps should be 1.0, not 1.0 + j1.0

gr-digital

• Async Decoder: several changes to improve performance robustness (see the commit log for more details)

gr-fec

• Tagged Decoder: correctly calculate the frame size for terminated CC decoder

gr-filter

• Fixed reverse parameters in fir_filter_with_buffer and pfb_arb_resampler, which could cause crashes
• Fixed PFB Arbitrary Resampler was ignoring attenuation parameter

gr-iio

• Set gain mode as specified (was always manual)
• Use the specified gain parameter for second channel (was same as first channel)

gr-qtgui

• Histogram Sink: calculate range of bins correctly to avoid strange distributions
• Save (to image) dialogs add file extensions and have a Save button (i.e., they work now)

gr-soapy

• Sources: add tags when the frequency changes

gr-uhd

• Support for more RFNoC blocks
  • Fosphor, which produces data to drive an on-screen, OpenGL-based renderer which is expected to be in the next release
  • Moving Average
  • Switchboard
  • Split Stream
• FFT: add properties for direction, magnitude and scaling
• RX Stream: flush after timeout
• Fully support multi-channel TX/RX (params were available for one one channel)

gr-vocoder

• Add a number of new codec modes for Codec2 and FreeDV

gr-zmq

• Selectable bind/connect to support more flexible ZMQ patterns and NAT'd networks
• Stream sources produce when available, instead of waiting for a buffer to fill, helping with latency

Modtool

• Use interp and decim keywords correctly when generating blocks

Build system and packaging

• Uninstall removes icons and desktop files
