GNU Radio v3.7.13.4

Dear Community,

we've released a new version of our 3.7 maintenance line – 3.7.13.4. Whilst this maintains binary compatibility with its predecessor, it fixes build breakage on systems with boost 1.67, it fixes a bunch of out-of-bound vector accesses (which on some systems triggered bug safeguards which aborted the applications doing them), and it also fixed a bug in how the "Skip Head" block deals with tags. Also, there was a logging bug that we've fixed.

My thanks go out to all our contributors, but especially to Cate Miller, Karel Pärlin and Paul wicks, all three first-time contributors to a release. Thanks everyone for the great help!

You can find the release as tag v3.7.13.4 (make sure to verify the GPG signature ;) ), on github under

https://github.com/gnuradio/gnuradio/releases/tag/v3.7.13.4

and

Happy hacking! Marcus

Fixed

Project Scope

  • Fix Boost 1.67 linking issue

    gnuradio-runtime

  • Logging: fixed issues where messages weren't properly written to stdout/stderr due to incorrect strings

    gr-analog

  • fmdet_cf's derivative coefficients were wrong.

    gr-blocks

  • skiphead used to incorrectly handle tags, now properly shifts

    gr-digital

  • qa_packet_format: Unit test used to potentially lock up due to incorrect conditionals

  • clock_recovery_cc, crc32_bb: Accessing the [0] element of an empty vector is UB, even if you don't use the result afterwards.

    gr-fec

  • polar_encoder/_common: Fixed multiple out-of-bound accesses due to insufficient vector length checks

    gr-filter

  • fft_filter, filter_delay: Accessing the [0] element of an empty vector is UB, even if you don't use the result afterwards.
