Release Candidate v3.10.1.0-rc1

This is mostly a bug fix release. It is API compatible with 3.10.X.Y releases. Code built against GNU Radio libraries (including OOTs) will likely need to be recompiled, as ABI compatibility is not guaranteed.

Runtime

• Add ownership and locking to hier_block2 to avoid crash/freeze after disconnect.

gr-analog

• Fix C++ code generation for random_uniform_source

gr-blocks

• Minimal implementation of a SigMF Sink, allowing users to easily try out generation SigMF output. SigMF uses a raw data file and a separate JSON metadata file. A SigMF Source is also provided. At this time, it is a wrapper around a File Source (the data files are compatible), but metadata is not processed.

gr-filter

• Bug fix: buses should now work with PFB channelizer and synthesizer.

gr-iio

• Various fixes for fmcomms2/3/4.

gr-uhd

• Bug fix: overflow count was uninitialized.
• Correct descriptor names in uhd_fpga_ddc/duc.

GRC

• Bug fix: initialize value for "priority" parameter in Python Snippets.
• Show blocks with "deprecated" flags as deprecated.
