Release 3.8.0.0

===============

Witness me!

Tonight, we release GNU Radio 3.8.0.0.

It's the first minor release version since more than six years, not
without pride this community stands to face the brightest future SDR on
general purpose hardware ever had.

Since we've not been documenting changes in the shape of a Changelog for
the whole of the development that happened since GNU Radio 3.7.0, I'm
afraid that these release notes will be more of a GLTL;DR (git log too
long; didn't read) than a detailed account of what has changed.

What has \_not*\* changed is the fact that GNU Radio is centered around
a very simple truth:

    Let the developers hack on DSP. Software interfaces are for humans,
    not the other way around.

And so, compared to the later 3.7 releases, nothing has fundamentally
modified the way one develops signal processing systems with GNU Radio:
You write blocks, and you combine blocks to be part of a larger signal
processing flow graph.

With that as a success story, we of course have faced quite a bit of
change in the systems we use to develop and in the people that develop
GNU Radio. This has lead to several changes that weren't compatible with
3.7.

**This is an excerpt only:**

Fixed
-----

Project Scope
~~~~~~~~~~~~~

-  Roughly 36 dBBug, (ETOOMANYBUGS)
-  Fixed .so versioning

Changed
-------

Project Scope
~~~~~~~~~~~~~

-  C++11
-  merged the wholeness of the ``next`` branch
-  Dependency version bumps: CMake, GCC, MSVC, Swig, Boost
-  New dependencies: MPIR/GMP, Qt5, gsm, codec2
-  Removed dependencies: libusb, Qt4, CppUnit
-  Python: Python 2 & Python 3 compatible. 3.8 will be the last
   Py2k-compatible release series
-  gengen was replaced by templates (if you don't know gengen, don't do
   any research; save yourself that sorrow)
-  Modern CMake (as far as feasible at this point)
-  VOLK version updated to v2.0.0
-  .clang-format file now dictates coding style
-  clang-format'ed the whole tree.
-  installed CMake files now tell about configuration

gnuradio-runtime
~~~~~~~~~~~~~~~~

-  reworked fractional tag time handling, especially in the context of
   resamplers

GRC
~~~

-  C++ generation as option
-  YAML instead of XML
-  removed ``blks2``
-  much better canvas tooling
-  consistent gobject usage
-  ROUNDED ARROWS

gr-qtgui
~~~~~~~~

-  moving from Qt4 to Qt5

gr-utils
~~~~~~~~

-  ``gr_modtool`` now vastly improved

gr-vocoder
~~~~~~~~~~

-  improved versatility
-  removed in-tree libgsm, libcodec2, use system-wide libs

Removed
-------

Project Scope
~~~~~~~~~~~~~

-  Modules ``gr-comedi``, ``gr-fcd`` and ``gr-wxgui`` are gone

gr-comedi
~~~~~~~~~

-  nobody could remember who used this, or for what. It has seen 0
   active code contributions in the 3.7 lifecycle

gr-digital
~~~~~~~~~~

-  python-based ``packet_encoder`` and related tools: Bugs that were
   sporadic and never fixed, so after long deprecation, we're removing
   it

gr-fcd
~~~~~~

-  since it's currently untestable by the CI, it's being removed, as
   there was no code contributions. Generally, we strive to include all
   batteries with GNU Radio. Re-integration within a more general SDR
   interface would be desirable.

gr-utils
~~~~~~~~

-  removed PyQwt (dead) based tools

gr-wxgui
~~~~~~~~

-  Unmaintained, breaks on increasingly many systems, always was slower
   than Qtgui. We've been starting to tell people to migrate to Qt since
   at least 2015. Now, we're finally removing it.
